                    FOR THE HALF YEAR ENDED 31 DECEMBER 2017

--------------------------------------------------------------------------------

Safety: We are committed to making our workplaces safer, as we achieve nothing
unless we achieve it safely

.   Tragically, we had two fatalities during the period, one at our Permian
    operations and one at Goonyella Riverside.

Maximise cash flow: Strong free cash generation underpinned by higher prices

.   Attributable profit of US$2.0 billion (includes an exceptional loss of
    US$2.0 billion predominantly related to the US tax reform) and Underlying
    attributable profit of US$4.1 billion.

.   Underlying EBITDA/(ii)/ of US$11.2 billion and Underlying EBITDA
    margin/(iii)/ of 53% reflect higher commodity prices and a solid operating
    performance.

.   Net operating cash flow of US$7.3 billion and free cash flow/(i)/ of US$4.9
    billion.

.   A negative productivity movement of US$496 million was largely due to
    anticipated factors. We remain on track to deliver productivity gains of
    US$2 billion over the two years to the end of the 2019 financial year,
    weighted to the second year.

Capital discipline: Delivering debt reduction and value accretive investments

.   Net debt/(i)/ down by US$0.9 billion from 30 June 2017 to US$15.4 billion
    reflecting strong free cash flow generation.

.   Capital and exploration expenditure/(v)/ increased by 6% to US$2.9 billion.
    Guidance unchanged at US$6.9 billion for the 2018 financial year and
    expected to remain below US$8 billion per annum for the 2019 and 2020
    financial years.

Value and returns: Detailed asset-level plans to increase shareholder value and
returns

.   The Board has determined to pay an interim dividend of 55 US cents per share
    which includes an additional amount of 17 US cents per share above the 50%
    minimum payout policy (equivalent to US$0.9 billion).

.   Underlying return on capital employed/(iii)/ of 12.8% (after tax) with
    further improvement expected.

.   Onshore US exit for value progressing to plan, with initial bids expected to
    be received in the June 2018 quarter.

                                                                  2017       2016     Change

(1) Where we have used alternate performance measures they are identified by a
    footnote, and definitions can be found on pages 23 and 24.

BHP Chief Executive Officer, Andrew Mackenzie:

"Higher commodity prices and a solid operating performance delivered free cash
flow of US$4.9 billion. We used this cash to further reduce net debt and
increase returns to shareholders through higher dividends. We are on track to
deliver further productivity gains of US$2 billion by the end of the 2019
financial year as we secure improvements in both operating and capital
productivity, aided by smarter technology application across our value chain.
Our capital expenditure program remains focused on high-return, low-risk
development opportunities in commodities where we see greatest potential. We
remain firm in our resolve to maximise cash flow, maintain discipline and
increase shareholder value and returns."

Results for the half year ended 31 December 2017

Safety is our highest priority

The health and safety of our employees and contractors, and that of the broader
communities in which we operate, are central to the success of our organisation.
Tragically, two of our colleagues died during the period, one at our Permian
Basin operations in November 2017 and one at Goonyella Riverside in August 2017.
Our Total Recordable Injury Frequency (TRIF) was 4.1 per million hours worked in
the December 2017 half year, a two per cent decrease from 30 June 2017. We are
committed to becoming safer through how we design our facilities and how we plan
and execute our work, with an increasing application of technology to remove
people from harms' way.

Making significant progress on the social and environmental remediation programs
in Brazil

BHP remains committed to supporting the Renova Foundation with the recovery of
communities and ecosystems affected by the Samarco tragedy.

The Renova Foundation's compensation program is making good progress. Over
260,000 claims for temporary interruption to water supplies immediately
following the dam failure have been resolved. The focus of the program is now
shifting to compensating for other damages including loss of property, equipment
and loss of income. The resettlement of the most impacted communities is
progressing, however, at a pace slower than planned due to regulatory and
licensing challenges. The river remediation programs continue to stabilise the
tailings material, resulting in improvements to water quality and aquatic
ecology.

Restart of Samarco's operations remains a focus but is subject to separate
negotiations with relevant parties and will occur only if it is safe,
economically viable and has the support of the community. Resuming operations
requires the granting of licences by state and federal authorities, community
hearings and an appropriate restructure of Samarco's debt.

In the December 2017 half year, BHP reported an exceptional loss of US$210
million (after tax) in relation to the Samarco dam failure. This includes
funding of US$50 million, direct costs of US$29 million, discount unwinding of
US$44 million and other movements in the provision, including foreign exchange,
of US$87 million. Additional commentary is included on page 42.

Financial performance

Earnings and margins

.   Attributable profit of US$2.0 billion includes an exceptional loss of US$2.0
    billion (after tax), compared to an attributable profit of US$3.2 billion,
    including an exceptional loss of US$40 million (after tax), in the prior
    period. The December 2017 half year exceptional loss is related to the US
    tax reform and Samarco dam failure. The December 2016 half year exceptional
    loss was related to the Samarco dam failure, partially offset by the
    reimbursement received on cancellation of the Caroona exploration licence.

.   Underlying attributable profit of US$4.1 billion, compared to US$3.2 billion
    in the prior period.

.   Profit from operations of US$6.7 billion, compared to US$6.1 billion in the
    prior period, has increased as a result of higher prices and volumes,
    partially offset by higher costs.

.   Underlying EBITDA of US$11.2 billion, with higher prices and volume
    productivity (in total US$2.6 billion) more than offsetting the impacts of
    higher costs, unfavourable exchange rate movements, inflation and other net
    movements (in total US$1.3 billion).

.   Underlying EBITDA margin of 53 per cent, compared with 54 per cent in the
    prior period.

                     News Release                          2

Productivity and costs

.   A negative movement in productivity of US$496 million was recorded
    reflecting: lower volumes and unfavourable fixed cost dilution at Olympic
    Dam as a result of the smelter maintenance campaign (US$202 million); the
    impact of reduced volumes at Queensland Coal and Petroleum (US$225 million);
    and a favourable change in estimated recoverable copper in the Escondida
    sulphide leach pad in the prior period (US$206 million); partially offset by
    an increase in Escondida copper volumes and lower labour and contractor
    costs at Western Australia Iron Ore (WAIO).

.   Productivity guidance remains unchanged, with US$2 billion of gains expected
    to be delivered over the two years to the end of the 2019 financial year,
    weighted to the second year.

.   Full year unit cost guidance(vi) remains unchanged for Petroleum, Copper,
    Iron Ore and Energy Coal (based on an exchange rate of AUD/USD 0.75 and
    USD/CLP 663).

.   Queensland Coal unit costs for the 2018 financial year are now expected to
    be US$66 per tonne (based on an exchange rate of AUD/USD 0.75), an increase
    from previous guidance of US$59 per tonne, as a result of reduced low-cost
    Broadmeadow and Blackwater volumes, production from higher cost pits and
    rising inflationary pressures. Unit costs for the second half of the 2018
    financial year are expected to be US$63 per tonne with challenging roof
    conditions at Broadmeadow expected to continue through the March 2018
    quarter.

.   Historical costs and guidance are summarised below:

                     BHP Results for the half year         3
                     ended 31 December 2017

Cash flow and balance sheet

.   Net operating cash flows of US$7.3 billion reflect higher commodity prices,
    a solid operating performance and a final corporate income tax payment in
    Australia of US$1.3 billion related to the prior year.

.   Free cash flow of US$4.9 billion. Our Onshore US assets remain free cash
    flow positive/(iii)/.

.   We continued to strengthen our balance sheet with a reduction in net debt of
    US$0.9 billion, to finish the period at US$15.4 billion (30 June 2017:
    US$16.3 billion; 31 December 2016: US$20.1 billion). This reduction reflects
    strong free cash generation during the period, offset by an increase in
    dividends to shareholders, record dividends paid to non-controlling
    interests of US$0.9 billion and a non-cash fair value adjustment of US$0.7
    billion related to interest rate and exchange rate movements/(viii)/.

.   Gearing ratio/(i)/ of 19.9 per cent (30 June 2017: 20.6 per cent;
    31 December 2016: 24.3 per cent).

.   We are on track to reach our net debt range of US$10 to US$15 billion before
    year-end and will maintain a strong balance sheet through the commodity
    price cycle. We are targeting the lower half of the net debt range while
    commodity prices remain elevated.

Dividends

.   The dividend policy provides for a minimum 50 per cent payout of Underlying
    attributable profit at every reporting period. The minimum dividend payment
    for the period is 38 US cents per share.

.   Recognising the importance of cash returns to shareholders, the Board has
    determined to pay an additional amount of 17 US cents per share or US$0.9
    billion, taking the interim dividend to 55 US cents per share or US$2.9
    billion. This is equivalent to a 72 per cent payout ratio.

Capital and exploration

.   Capital and exploration expenditure of US$2.9 billion, up six per cent in
    the December 2017 half year, included maintenance spend/(ix)/ of US$1.0
    billion and exploration of US$0.5 billion.

.   Capital and exploration expenditure guidance is unchanged at US$6.9 billion
    for the 2018 financial year, as a decrease in Onshore US capital expenditure
    of US$100 million is offset by unfavourable exchange rate movements.

.   A US$0.9 billion exploration program is planned for the 2018 financial year
    and includes petroleum exploration expenditure of US$715 million.

.   We expect capital and exploration expenditure to remain below US$8 billion
    per annum in the 2019 and 2020 financial years, subject to exchange rate
    movements.

Capital allocation framework

Adherence to our capital allocation framework aims to balance value creation,
cash returns to shareholders and balance sheet strength in a transparent and
consistent manner, and is embedded in every capital decision we make. Our
balance sheet is strong and remains a fundamental enabler of our strategy. This
will protect the Group through periods of heightened volatility and support
counter cyclical investments as we move through the cycle.

                     BHP Results for the half year         5
                     ended 31 December 2017

Outlook

Economic outlook

World economic growth was in the range of three and a half to three and three
quarters per cent in the 2017 calendar year. A similar outcome is expected in
the 2018 calendar year.

China's economic growth is expected to slow modestly in the 2018 calendar year,
close to the lower end of the official GDP target range of six and a half to
seven per cent, as continued strength in infrastructure and resilience in
external trade is offset by a cooling of growth rates in the housing and
automobile markets.

The US economy should see a near-term boost to growth with the passing of the US
Tax Cuts and Jobs Act (the TCJA). In Europe and Japan, where the limits of
monetary policy effectiveness may have been reached, any upside on growth in the
medium term will have to come from external demand sources. India's economy is
on a healthy growth trajectory, supported by positive reform signposts.

Commodities outlook

Crude oil prices trended higher during the December 2017 half year. Production
discipline by OPEC members and non-OPEC participants (the 'Vienna Group') and
strong demand growth contributed to a substantial reduction in the inventory
overhang. The tighter market, rising geopolitical tensions, unplanned supply
outages, plateauing of the US rig count and extension of Vienna Group production
cuts aided market sentiment. A roughly balanced market is forecast for the 2018
calendar year.

The US domestic gas price was relatively stable as growth in exports, strong
power demand over summer and delays to North East pipeline projects helped
eliminate the storage surplus relative to the five-year average. We anticipate
that the market will return to surplus in the 2018 calendar year, as record US
production is facilitated by the start-up of major North East pipelines.

Copper prices rose over the December 2017 half year. Solid global consumption
was underpinned by continued strength in China, in particular from consumer
durables. On the supply side, the announcement that China would ban lower-grade
copper scrap imports and the potential for supply disruptions due to the large
number of upcoming labour negotiations in South America drove sentiment. Over
the next few years, the global copper market is expected to remain finely
balanced and vulnerable to supply shocks, particularly in the concentrate
segment.

The global steel industry continued its recovery in the December 2017 half year,
with production growth led by emerging markets. China's steel supply-side
reforms have resulted in a structural improvement in industry profitability.
China's steel production growth is expected to moderate in the 2018 calendar
year due to a cooling in the housing and automobile sectors. However, the
recovery in the rest of the world is likely to continue, with solid demand
conditions and lower Chinese steel exports.

Iron ore prices improved over the December 2017 half year. Demand for high-grade
products remained firm on the back of high steel margins, which benefitted from
Chinese steel supply-side reforms and winter production restrictions. This has
resulted in an elevated price differential between high and low-grade ore price
indexes. In the medium to longer term, ongoing Chinese supply-side reforms, the
shift of steel capacity to coastal regions and more stringent environmental
policies are expected to underpin demand for high-quality seaborne iron ore.

Metallurgical coal prices strengthened in the December 2017 half year. Chinese
demand for higher quality metallurgical coal remained firm throughout the period
despite the onset of winter emission restrictions. Additionally, domestic supply
was constrained due to safety and environmental concerns. High prices have
incentivised additional seaborne supply from the US and Mozambique. In the
medium term, China's coal supply-side reforms and environmental considerations
will support demand for higher quality metallurgical coal.

(1) Exceptional items of US$(166) million excludes net finance costs of US$(44)
    million included in the total US$(210) million related to the Samarco dam
    failure.

Profit from operations has increased as a result of favourable realised price
movements across all major commodities and higher volumes, partially offset by
higher costs, impairment charges predominantly related to conveyors at Escondida
and higher depreciation charges following the commissioning of the Escondida
Water Supply project.

Depreciation, amortisation and impairments

Depreciation, amortisation and impairments increased by US$422 million to US$4.3
billion, reflecting impairment charges predominantly related to conveyors at
Escondida and higher depreciation following the commissioning of the Escondida
Water Supply project in June 2017.

Net finance costs

Net finance costs increased by US$93 million to US$670 million due to costs
related to the September 2017 bond repurchase program and higher benchmark
interest rates in the period. This was partially offset by a lower average debt
balance following the repayment on maturity of Group debt and the bond
repurchase program.

The Group's adjusted effective tax rate/(iii)/, which excludes the influence of
exchange rate movements and exceptional items, was 28.1 per cent (31 December
2016: 34.7 per cent). The adjusted effective tax rate reflects the impact of
higher profits from equity accounted investments and depletion allowances
claimed in the United States. As a result, the adjusted effective tax rate is
now expected to be in the range of 30 to 35 per cent for the 2018 financial
year.

Other royalty and excise arrangements which are not profit based are recognised
as operating costs within Profit before taxation. These amounted to US$986
million during the period (31 December 2016: US$963 million).

                     ended 31 December 2017

On 22 December 2017, the US President signed the TCJA into law. The TCJA
(effective 1 January 2018) includes a broad range of tax reforms affecting the
Group, including, but not limited to, a reduction of the US corporate tax rate
from 35 per cent to 21 per cent and changes to international tax provisions. As
a result of the TCJA, the Group has recognised an exceptional income tax charge
of US$1,828 million (refer exceptional items footnote (2) below for further
details). Longer term, we expect US attributable profits to be positively
impacted by the lower US corporate tax rate.

Exceptional items

The following table sets out the exceptional items for the December 2017 half
year. Additional commentary is included on page 34.

Debt management and liquidity

During the December 2017 half year, the Group continued to focus on debt
reduction, with no new debt issued and an A$1.0 billion Australian bond repaid
at maturity. In addition, a bond repurchase program of US$2.9 billion was
completed on 22 September 2017. The total cost in relation to the repurchase
program was US$71 million, which has been reported in net finance costs. The
program was funded by BHP's strong cash position and targeted short-dated US
dollar, Euro and GBP bonds. The early repayment of the bonds has extended BHP's
average debt maturity profile. The repayment of maturing debt and the bond
repurchase program, partially offset by fair value adjustments, contributed to a
US$2.8 billion overall decrease in the Group's gross debt, from US$30.5 billion
at 30 June 2017 to US$27.7 billion at 31 December 2017.

At the subsidiary level, Escondida issued US$0.5 billion of new long-term debt
to fund capital expenditure and for general corporate purposes.

The Group has a US$6.0 billion commercial paper program backed by a US$6.0
billion revolving credit facility which expires in May 2021. As at 31 December
2017, the Group had no outstanding US commercial paper, no drawn amount under
the revolving credit facility and US$12.3 billion in cash and cash equivalents.

The Board and management regularly review the Dual Listed Company (DLC)
structure and our portfolio of assets so as to optimise long-term value for all
shareholders. We have considered unification of the DLC structure a number of
times over the past years, and will keep it under review. We would change the
DLC structure if it were in the best interests of all shareholders. Our view on
unification of the DLC structure is based on cost and benefit analysis.
Currently, we consider that the costs and risks of collapsing the DLC outweigh
the potential benefits.

Underlying EBITDA for Petroleum increased by US$35 million to US$2.0 billion in
the December 2017 half year.

(1) Average realised price: crude and condensate oil US$54/bbl (2016:

    (2016: US$6.35/Mscf).
(2) Other includes: exchange rate; inflation; ceased and sold operations; other
    items. Other items includes the impact from revaluation of embedded
    derivatives in Trinidad and Tobago gas contract of US$97 million loss (2016:
    US$46 million loss).

Total petroleum production for the December 2017 half year decreased by seven
per cent to 99 MMboe due to the impact of Hurricane Harvey and Hurricane Nate on
US petroleum assets and natural field decline. Conventional production declined
by three per cent to 64 MMboe and Onshore US production declined by 13 per cent
to 35 MMboe.

Controllable cash costs increased by US$67 million and includes:

.   US$91 million - unfavourable fixed cost dilution from declining volumes;

.   US$61 million - planned maintenance activity at Atlantis, Macedon and
    Pyrenees; and

.   US$(81) million - lower exploration expenses due to the Burrokeet wells
    write-off in the December 2016 half year.

Profit on sale of assets decreased by US$187 million reflecting the divestment
of a small portion of the Hawkville acreage, completed in the September 2017
quarter, more than offset by the sale of 50 per cent of BHP's interest in the
undeveloped Scarborough area gas fields in the prior period.

Conventional unit costs increased by 23 per cent to US$10.38 per barrel of oil
equivalent during the December 2017 half year, due to the impact of lower
volumes and unfavourable foreign exchange movements. Unit cost guidance for the
2018 financial year remains unchanged at approximately US$10 per barrel (based
on an exchange rate of AUD/USD 0.75).

Onshore US development activity

Onshore US drilling and development expenditure for the December 2017 half year
was US$336 million (U$511 million on an activity basis), 23 per cent higher than
the same period last year reflecting an increase from three to nine rigs.

(2) Can vary between periods based on changes in rig activity and the inventory

We continue to drill longer laterals and complete larger frac jobs. By changing
the well design, we enhanced staggered laterals and demonstrated commerciality
of Upper and Lower Eagle Ford co-development and confirmed first year production
improvements associated with larger completions in the Permian. These longer and
more complex laterals are reflected in an overall increase of our Onshore US
drilling and completion costs per well, but are more than offset by the
additional well productivity. During the December 2017 half year, our Onshore US
assets were free cash flow positive/(iii)/.

We expect to lower our rig count during the second half of the 2018 financial
year as rig contracts expire and we adjust our capital plans to optimise value
for our planned exit. Onshore US production volumes for the 2019 financial year
are expected to remain broadly unchanged from previous guidance, as enhanced
well performance offsets lower rig activity.

We continue to progress a number of alternatives to exit our Onshore US assets
for value. We have commenced marketing each of the fields and the data room for
the Fayetteville field has been opened. We continue preparing all appropriate
documentation ahead of data rooms for the remaining fields being opened in March
2018. We expect to receive trade sale bids during the June 2018 quarter,
evaluate and negotiate those bids in the September 2018 quarter and potentially
announce completed transactions in the first half of the 2019 financial year. In
parallel, we continue to explore potential asset swap opportunities and exit via
demerger or Initial Public Offering.

Petroleum exploration

Petroleum exploration expenditure for the December 2017 half year was US$378
million, of which US$137 million was expensed. Activity for the period was
largely focused in the deepwater Gulf of Mexico.

In the Gulf of Mexico, no commercial hydrocarbons were encountered at Scimitar.
The well was plugged and abandoned in February 2018, with the associated
exploration costs to be expensed in the second half of the 2018 financial year.
The Wildling-2 well and side track were successfully completed in the September
2017 quarter and found oil in multiple horizons. Evaluation is ongoing to assess
the scale of the discovery and we are preparing our appraisal plans for Wildling
with the expectation to continue drilling in the 2019 financial year.

In Mexico, the Exploration and Appraisal plan has been endorsed by Pemex and
approval from Mexico's National Hydrocarbon Commission was granted in February
2018. Planning continues for exploration and appraisal wells on Trion which are
expected to be drilled in the 2019 financial year.

In Trinidad and Tobago, we continue appraisal work in the Southern Gas region
(known as Magellan) to assess the potential commercialisation of the gas
discovery at LeClerc and follow-on potential at the Victoria and Concepcion
prospects. Preparations continue for Phase 2 deepwater exploration which is
expected to commence in the June 2018 quarter.

In Australia, the seismic survey in the Exmouth sub-basin is progressing to plan
with processed data to be delivered during the June 2018 quarter.

Copper

Underlying EBITDA for the December 2017 half year increased by US$1.5 billion to
US$3.2 billion.

                                                                           US$M

(1) Average realised price: copper US$3.20/lb (2016: US$2.41/lb).
(2) Non-cash includes: development stripping capitalisation and depletion.
(3) One-off items reflects the state-wide power outage and resultant shutdown at
    Olympic Dam in the December 2016 half year.
(4) Other includes: fuel and energy; other items (including profit from equity
    accounted investments).

Total copper production for the December 2017 half year increased by 17 per cent
to 833 kt due to increased volumes at Escondida (ramp-up of the Los Colorados
Extension project), which more than offset reduced volumes at Olympic Dam
(planned smelter maintenance campaign recently completed). Operations at Olympic
Dam continue to ramp-up to full-capacity during the March 2018 quarter, with
production guidance unchanged at 150 kt for the 2018 financial year.

Controllable cash costs increased by US$610 million and includes:

.   US$114 million - unfavourable fixed cost dilution at Olympic Dam as a result
    of the smelter maintenance campaign;

.   US$106 million - increased labour and contractor costs at Olympic Dam,
    primarily to support operating stability projects and expansion studies;

.   US$206 million - a change in estimated recoverable copper contained in the
    Escondida sulphide leach pad which benefited costs in the prior period; and

.   US$195 million - ore inventory movements at Escondida and Pampa Norte.

Non-cash costs (including development stripping) decreased by US$253 million
reflecting:

.   increased waste movement at Escondida and Pampa Norte reflected in higher
    capitalised stripping; and

.   increased underground mine capitalisation at Olympic Dam as mining expands
    into the Southern Mine Area.

As a result, unit costs at our operated copper assets increased by 17 per cent
to US$1.27 per pound during the December 2017 half year including a 16 per cent
increase at Escondida to US$1.06 per pound partially due to unfavourable
exchange rate movements. Escondida unit cost guidance for the 2018 financial
year remains unchanged at approximately US$1.00 per pound (based on an exchange
rate of USD/CLP 663).

(1) Average realised price: iron ore US$57/wmt, FOB (2016: US$55/wmt, FOB).
(2) Other includes: fuel and energy; non-cash; asset sales.

Total iron ore production for the December 2017 half year was in line with the
prior period at 117 Mt(x), as record production at Jimblebar and Mining Area C
was offset by the impact of lower opening stockpile levels following the Mt
Whaleback fire in June 2017 and planned maintenance.

BHP received regulatory approval to increase capacity at its Port Hedland
operations to 290 Mtpa (100 per cent basis) on 16 February 2018 and expects to
reach this run rate by the end of the 2019 financial year.

Controllable cash costs decreased by US$137 million, primarily due to continued
reductions in labour and contractor costs.

WAIO unit costs declined by one per cent to US$14.90 per tonne during the
December 2017 half year, despite the impact of a stronger Australian dollar. In
local currency terms, WAIO unit costs declined by six per cent.

Unit cost guidance for the 2018 financial year remains unchanged at less than
US$14 per tonne (based on an exchange rate of AUD/USD 0.75). In the medium term,
we expect to lower our unit costs to less than US$13 per tonne.

South Flank feasibility study is progressing, with the project expected to be
submitted for Board approval in the middle of the 2018 calendar year. The
capital cost for the 80 Mtpa (100 per cent basis) sustaining mine is now
expected to be around US$45 per tonne, reflecting a stronger Australian dollar
and updated estimates as the project planning has progressed. The capital cost
fits within WAIO's previously indicated average sustaining capital expenditure
of US$4 per tonne (plus or minus 50 per cent in any given year) over the medium
term. The South Flank project, which will leverage and expand the existing
Mining Area C hub, will increase WAIO's average Fe grade from 61 per cent to 62
per cent and lump proportion for our overall product mix from approximately 25
per cent to 35 per cent, supporting WAIO's ability to benefit from sustained
higher premiums for lump and higher quality fines.

Guidance for production and unit costs for the 2018 financial year is also
detailed on page 3. Capital expenditure and project information is detailed on
pages 4 and 5.

Underlying EBITDA for the December 2017 half year decreased by US$221 million to
US$1.8 billion.

                                                                           US$M

Underlying EBITDA for the half year ended 31 December 2017............... 1,790
                                                                          -----

(1) Average realised price: hard coking coal US$182/t (2016: US$179/t); weak
    coking coal US$121/t (2016: US$122/t); thermal coal US$87/t (2016: US$74/t).
(2) Other includes: fuel and energy; asset sales; ceased and sold operations;
    other items (including profit from equity accounted investments).

Metallurgical coal production decreased by four per cent to 20 Mt(x) as record
production at four Queensland Coal mines was offset by lower volumes at
Broadmeadow (roof conditions; expected to continue through the March 2018
quarter) and Blackwater (geotechnical issues triggered by wet weather). Guidance
for the 2018 financial year has been reduced to between 41 and 43 Mt.

Energy coal production increased by four per cent to 14 Mt(x) as a strong
performance at New South Wales Energy Coal (NSWEC) was offset by the impacts of
wet weather at Cerrejon.

Controllable cash costs increased by US$191 million and includes:

.   US$134 million - primarily reflects unfavourable fixed cost dilution from
    reduced volumes at Broadmeadow and Blackwater, and compensatory increased
    production from higher cost pits, at BHP Billiton Mitsubishi Alliance (BMA);
    and

.   US$11 million - increased contractor activity partially offset by improved
    ultra-class truck productivity at NSWEC.

Queensland Coal unit costs increased by 26 per cent to US$71 per tonne in the
December 2017 half year, including the impact of a stronger Australian dollar.
Unit costs for the 2018 financial year are now expected to be US$66 per tonne
(based on an exchange rate of AUD/USD 0.75), an increase from previous guidance
of US$59 per tonne, reflecting reduced Broadmeadow and Blackwater volumes,
increased production from higher cost pits and rising inflationary pressures.
Unit costs for the second half of the 2018 financial year are expected to be
US$63 per tonne. In the medium term, we expect to lower our unit costs to
approximately US$54 per tonne.

NSWEC unit costs increased by four per cent to US$48 per tonne in the December
2017 half year due to the impact of a stronger Australian dollar. Unit cost
guidance for the 2018 financial year remains unchanged at US$46 per tonne (based
on an exchange rate of AUD/USD 0.75). In the medium term, we expect to lower our
unit costs further to approximately US$40 per tonne.

                     BHP Results for the half year         21
                     ended 31 December 2017

Group and unallocated items

Underlying EBITDA loss for Group and unallocated items increased by US$68
million to US$89 million in the December 2017 half year, as a strong performance
at Nickel West was more than offset by increased corporate spend on technology
projects and unfavourable exchange rate impacts on corporate provision balances.

Nickel West's Underlying EBITDA increased by 92 per cent to US$71 million for
the December 2017 half year, predominantly due to higher prices and improved
mill utilisation and concentrator recoveries.

The following footnotes apply to this Results Announcement:

(i)    We use other financial measures (each of which is calculated with
       reference to IFRS measures) to assess our performance, which are defined
       below:

       .   Free cash flow - comprises net operating cash flows less net
           investing cash flows.

       .   Gearing ratio - represents the ratio of net debt to net debt plus net
           assets.

       .   Net debt - comprises Interest bearing liabilities less Cash and cash
           equivalents for the Group at the reporting date.

(ii)   We use various alternate performance measures to reflect our underlying
       performance. Our two primary measures of performance are Underlying
       attributable profit and Underlying EBITDA.

       We believe these alternate performance measures provide useful
       information, but should not be considered as an indication of, or as a
       substitute for, Attributable profit and other statutory measures as an
       indicator of actual operating performance or as an alternative to cash
       flow as a measure of liquidity.

       We consider Underlying attributable profit to be a key measure that
       provides insight on the amount of profit available to distribute to
       shareholders, which aligns to our purpose as outlined in Our Charter.
       Underlying attributable profit is also the key performance indicator
       against which short-term incentive outcomes for our senior executives are
       measured and, in our view, is a relevant measure to assess the financial
       performance of BHP for this purpose.

       Underlying EBITDA is the key alternate performance measure that
       management uses internally to assess the performance of the Group's
       segments and make decisions on the allocation of resources. In the
       Group's view, this is more relevant to capital intensive industries with
       long-life assets.

       .   Underlying attributable profit is Profit after taxation attributable
           to owners of the BHP Group (also referred to as Attributable
           profit') excluding any exceptional items attributable to the owners
           of the BHP Group.

       .   Underlying EBITDA is Earnings before net finance costs, depreciation,
           amortisation and impairments, taxation expense, and exceptional
           items. Underlying EBITDA includes net finance costs and taxation
           expense, depreciation, amortisation and impairments related to equity
           accounted investments of US$318 million (2016: US$267 million) and
           excludes exceptional items of US$137 million (2016: US$48 million)
           related to share of loss from equity accounted investments.

       .   Underlying EBIT is Underlying EBITDA, including depreciation,
           amortisation and impairments of US$4,336 million for the December
           2017 half year (2016: US$3,914 million). Underlying EBIT includes net
           finance costs and taxation expense of US$211 million (2016: US$156
           million) related to equity accounted investments and excludes
           exceptional items of US$137 million (2016: US$48 million) related to
           share of loss from equity accounted investments.

(iii)  Further alternate performance measures are defined as follows:

       .   Adjusted effective tax rate - comprises Total taxation expense
           excluding exceptional items and exchange rate movements included in
           taxation expense divided by Profit before taxation and exceptional
           items. Management believes this measure provides useful information
           regarding the tax impacts from underlying operations.

       .   Net operating assets - represents operating assets net of operating
           liabilities including the carrying value of equity accounted
           investments and predominantly excludes cash balances, loans to
           associates, interest bearing liabilities and deferred tax balances.
           The carrying value of investments accounted for using the equity
           accounted method represents the balance of the Group's investment in
           equity accounted investments, with no adjustment for any cash
           balances, interest bearing liabilities and deferred tax balances of
           the equity accounted investment.

       .   Operating assets free cash flow - comprises net operating cash flows
           adjusted for dividends received, net interest received/(paid) and net
           income tax and royalty-related taxation refunded/(paid) less net
           investing cash flows. Dividends received, net interest and net income
           tax and royalty-related taxation are not allocated to operating asset
           free cash flow as financing structures and tax regimes differ across
           the Group's assets and substantial components of the Group's interest
           and tax charges are levied at a Group level rather than an
           operational level.

       .   Underlying basic earnings per share - represents underlying
           attributable profit divided by the weighted average number of basic
           shares.

       .   Underlying EBITDA margin - comprises Underlying EBITDA excluding
           third party product EBITDA, divided by revenue excluding third party
           product revenue.

       .   Underlying return on capital employed (ROCE) - represents annualised
           attributable profit after tax excluding exceptional items and net
           finance costs (after tax) divided by average capital employed.
           Average capital employed is calculated as the average of net assets
           less net debt for the last two reporting periods.

       The method of calculation of the Principal factors that affect Underlying
       EBITDA is as follows:

       References to operation/s in each Principal factor excludes equity
       accounted investments which are included within 'Other'.

       .   Change in sales prices - Change in average realised price for each
           operation from the corresponding period to the current period,
           multiplied by current period volumes.

       .   Price-linked costs - Change in price-linked costs for each operation
           from the corresponding period to the current period, multiplied by
           current period volumes.

       .   Productivity volumes - Change in volumes for each operation not
           included in the Growth category from the corresponding period to the
           current period, multiplied by the prior year Underlying EBITDA
           margin. Used to determine changes in productivity in footnote /(iv)/.

       .   Growth volumes - Volume - Growth comprises Underlying EBITDA for
           operations that are new or acquired in the current period minus
           Underlying EBITDA for operations that are new or acquired in the
           corresponding period, change in volumes for operations identified as
           a Growth project from the corresponding period to the current period
           multiplied by the prior year Underlying EBITDA margin, and change in
           volume for our petroleum assets from the corresponding period to the
           current period multiplied by the prior year Underlying EBITDA margin.

                     BHP Results for the half year         23
                     ended 31 December 2017

       .   Controllable cash costs - comprises operating cash costs and
           exploration and business development costs. Management believes this
           measure provides useful information regarding the Group's financial
           performance because it considers these expenses to be the principal
           operating and overhead expenses that are most directly under the
           Group's control. Used to determine changes in productivity in
           footnote /(iv)/.

       .   Operating cash costs - Change in total costs, other than price-linked
           costs, exchange rates, inflation on costs, fuel and energy costs,
           non-cash costs and one-off items as defined below for each operation
           from the corresponding period to the current period.

       .   Exploration and business development - Exploration and business
           development expense in the current period minus exploration and
           business development expense in the corresponding period.

       .   Exchange rates - Change in exchange rate multiplied by current period
           local currency revenue and expenses. The majority of the Company's
           selling prices are denominated in US dollars and so there is little
           impact of exchange rate changes on Revenue.

       .   Inflation - Change in inflation rate applied to expenses, other than
           depreciation and amortisation, price-linked costs, exploration and
           business development expenses, expenses in ceased and sold operations
           and expenses in new and acquired operations.

       .   Fuel and energy - Fuel and energy expense in the current period minus
           fuel and energy expense in the corresponding period.

       .   Non-cash - Includes non-cash items mainly depletion of stripping
           capitalised.

       .   One-off items - Change in costs exceeding a pre-determined threshold
           associated with an unexpected event that had not occurred in the last
           two years and is not reasonably likely to occur within the next two
           years.

       .   Asset sales - Profit/loss on the sale of assets or operations in the
           current period minus profit/loss on sale in the corresponding period.

       .   Ceased and sold operations - Underlying EBITDA for operations that
           ceased or were sold in the current period minus Underlying EBITDA for
           operations that ceased or were sold in the corresponding period.

       .   Other - Share of operating profit from equity accounted investments
           for the period minus share of operating profit from equity accounted
           investments in the corresponding period and variances not explained
           by the above factors.

(iv)   Represents changes in controllable cash costs (refer to footnote (iii)),
       changes in volumes attributed to productivity (refer to definition of
       'productivity volumes' in footnote (iii)) and changes in capitalised
       exploration. Changes in capitalised exploration is capitalised
       exploration in the current period less capitalised exploration in the
       prior period.

(v)    Capital and exploration expenditure represents purchases of property,
       plant and equipment plus exploration expenditure from the Consolidated
       Cash Flow Statement.

(vi)   Conventional petroleum unit cash costs exclude inventory movements,
       freight, and third party and exploration expense; WAIO, Queensland Coal
       and NSWEC unit cash costs exclude freight and royalties; Escondida unit
       cash costs include the grade decline and exclude freight and treatment
       and refining charges and are net of by-product credits. 2018 financial
       year unit cost guidance is based on exchange rates of AUD/USD 0.75 and
       USD/CLP 663. Other forward-looking guidance is based on internal exchange
       rate assumptions.

(vii)  Copper equivalent production based on 2017 financial year average
       realised prices.

(viii) Balances relating to hedging derivatives of external debt included within
       net other financial assets/(liabilities) for the half year ended 31
       December 2017 was US$0.1 billion (30 June 2017: US$(0.7) billion).The
       movement of US$0.8 billion includes a non-cash fair value adjustment of
       US$0.7 billion, which offsets in net debt, and US$0.1 billion of other
       cash movements.

(ix)   Maintenance capital includes non-discretionary spend for the following
       purposes: deferred development and production stripping; risk reduction,
       compliance and asset integrity.

(x)    Iron ore production and guidance excludes production from Samarco; Energy
       Coal production and guidance excludes production from New Mexico Coal
       following divestments; Metallurgical coal production and guidance
       excludes production from Haju following the divestment of IndoMet Coal.

Notes to the Financial Information

1.  Basis of preparation

This general purpose financial report for the half year ended 31 December 2017
is unaudited and has been prepared in accordance with IAS 34 'Interim Financial
Reporting' as issued by the International Accounting Standards Board (IASB) and
as adopted by the European Union (EU), AASB 134 'Interim Financial Reporting' as
issued by the Australian Accounting Standards Board (AASB) and the Disclosure
and Transparency Rules of the Financial Conduct Authority in the United Kingdom
and the Australian Corporations Act 2001 as applicable to interim financial
reporting.

The half year financial statements represent a 'condensed set of financial
statements' as referred to in the UK Disclosure and Transparency Rules issued by
the Financial Conduct Authority. Accordingly, they do not include all of the
information required for a full annual report and are to be read in conjunction
with the most recent annual financial report. The comparative figures for the
financial year ended 30 June 2017 are not the statutory accounts of the Group
for that financial year. Those accounts, which were prepared under IFRS, have
been reported on by the Company's auditor and delivered to the registrar of
companies. The auditor has reported on those accounts; the report was
unqualified, did not include a reference to any matters to which the auditors
drew attention by way of emphasis without qualifying their report and did not
contain statements under Section 498 (2) or (3) of the UK Companies Act 2006.

The half year financial statements have been prepared on the basis of the
accounting policies and methods of computation consistent with those applied in
the 30 June 2017 annual financial statements contained within the Annual Report
of the Group.

The directors have made an assessment of the Group's ability to continue as a
going concern and consider it appropriate to adopt the going concern basis of
accounting in preparing the half year financial statements.

The following new significant accounting standards are not yet effective, but
may have an impact on the Group in financial years commencing on or after 1
January 2018:

                                                                                                    Application
                                                                                                    date for the
                                                                                  Application date financial year

Contracts with      principal revenue streams, particularly key terms and
Customers'          conditions which may impact revenue recognition.

                    During FY2018, detailed reviews of individual contracts
                    across the Groups key commodities has commenced. To date,
                    no significant measurement differences have been identified
                    in addition to those outlined in the Groups Annual Report
                    for the year ended 30 June 2017.

                    During FY2018, detailed analysis has commenced focusing on
                    changes to the calculation of credit loss provisions on
                    financial assets, with no significant impacts being
                    identified to date. Application of the revised hedge
                    accounting model and other impacts of the standard continue
                    to be assessed.
------------------------------------------------------------------------------------------------------------------

                    An assessment of likely system requirements and processes is
                    ongoing.

In addition to the above, other accounting standards, amendments and
interpretations that have been issued and will be applicable in future periods
are subject to ongoing assessment, however no significant impacts have been
identified to date.

These standards have not been applied in the preparation of these half year
financial statements.

All amounts are expressed in US dollars unless otherwise stated. The Group's
presentation currency and the functional currency of the majority of its
operations is US dollars as this is the principal currency of the economic
environment in which it operates. Amounts in this financial information have,
unless otherwise indicated, been rounded to the nearest million dollars.

US tax reform

On 22 December 2017, the US President signed the Tax Cuts and Jobs Act (the
TCJA) into law. The TCJA (effective 1 January 2018) includes a broad range of
tax reforms affecting the Group, including, but not limited to, a reduction in
the US corporate tax rate from 35 per cent to 21 per cent and changes to
international tax provisions.

Following enactment of the TCJA, the Group has recognised an exceptional income
tax charge of US$1,828 million, primarily relating to the reduced US corporate
income tax rate, which resulted in re-measurement of the Group's deferred tax
position and impairment of foreign tax credits due to reduced forecast
utilisation, together with tax charges on the deemed repatriation of accumulated
earnings of non-US subsidiaries.

(1) Comprising US$797 million repatriation tax and US$603 million of previously
    unrecognised tax credits.
(2) The profit from equity accounted investments and related expenses is net of
    income tax. This item removes the prima facie tax effect on such profits and
    related expenses.

The Group operates across many tax jurisdictions. Application of tax law can be
complex and requires judgement to assess risk and estimate outcomes,
particularly in relation to the Group's cross-border operations and
transactions.

US tax reform

As per note 2 - Exceptional items, the impact of the TCJA has been included in
the Financial Statements. The TCJA includes a number of complex provisions, the
application of which are potentially subject to further implementation and
regulatory guidance, and possible elections. Judgements are required about the
application of the TCJA and its interaction with income tax accounting
principles.

5. Income tax expense (continued)

Key judgements and estimates

The Group has made preliminary determinations, based on currently available
implementation guidance. However, judgements made are subject to risk and
uncertainty, hence there is a possibility that changes in circumstances or
future regulatory guidance may alter the judgements made, which may potentially
impact the amount of deferred or current taxes recognised on the balance sheet
and the amount of other tax balances not yet recognised.

The significant judgements and estimates include:

.   The TCJA requires mandatory deemed repatriation of post-1986 undistributed
    earnings and profits from specific non-US subsidiaries. In assessing the
    potential tax charge, the Group has made certain assumptions as to offsets
    available under the TCJA, including the use of available foreign tax credits
    to partially offset the deemed repatriation tax liability.

.   The US will continue to tax foreign income from partnerships on a worldwide
    basis with the ability to offset US tax liabilities on foreign earnings with
    a credit for taxes paid in foreign jurisdictions. The reduction in the US
    corporate tax rate and the revised differential in tax rates with other
    jurisdictions impacts the forecasted utilisation of these foreign tax
    credits. The Group has made certain assumptions as to the utilisation of
    available foreign tax credits based on an assessment of probable future US
    income tax.

Where further clarifying regulatory guidance is issued, this may potentially
impact the assumptions made and result in a different outcome.

(1) The calculation of the number of ordinary shares used in the computation of
    basic earnings per share is the aggregate of the weighted average number of
    ordinary shares of BHP Billiton Limited and BHP Billiton Plc outstanding
    during the period after deduction of the number of shares held by the
    Billiton Employee Share Ownership Plan Trust and the BHP Billiton Limited
    Employee Equity Trust.

(2) For the purposes of calculating diluted earnings per share, the effect of 15
    million of dilutive shares has been taken into account for the half year
    ended 31 December 2017 (31 December 2016: 14 million shares; 30 June 2017:
    13 million shares). The Group's only potential dilutive ordinary shares are
    share awards granted under employee share ownership plans. Diluted earnings
    per share calculation excludes instruments which are considered
    antidilutive.

    At 31 December 2017, there are no instruments which are considered
    antidilutive (31 December 2016: nil; 30 June 2017: nil).

(3) Each American Depositary Share represents twice the earnings for BHP
    ordinary shares.

(1) 5.5 per cent dividend on 50,000 preference shares of(pound)1 each determined
    and paid annually (31 December 2016: 5.5 per cent; 30 June 2017: 5.5 per
    cent).

Subsequent to the half year ended 31 December 2017, on 20 February 2018, BHP
Billiton Limited and BHP Billiton Plc determined an interim dividend of 55 US
cents per share (US$2,928 million), which will be paid on 27 March 2018.

At 31 December 2017, BHP Billiton Limited had 3,211 million ordinary shares on
issue and held by the public and BHP Billiton Plc had 2,112 million ordinary
shares on issue and held by the public. No shares in BHP Billiton Limited were
held by BHP Billiton Plc at 31 December 2017 (31 December 2016: nil, 30 June
2017: nil).

Dividends paid during the period differs from the amount of dividends paid in
the Cash Flow Statement as a result of foreign exchange gains and losses
relating to the timing of equity distributions between the record date and the
payment date.

The Dual Listed Company merger terms require that ordinary shareholders of BHP
Billiton Limited and BHP Billiton Plc are paid equal cash dividends on a per
share basis. Each American Depositary Share (ADS) represents two ordinary shares
of BHP Billiton Limited or BHP Billiton Plc. Dividends determined on each ADS
represent twice the dividend determined on BHP ordinary shares.

BHP Billiton Limited dividends for all periods presented are, or will be, fully
franked based on a tax rate of 30 per cent.

9. Financial risk management - Fair values

All financial assets and financial liabilities, other than derivatives, are
initially recognised at the fair value of consideration paid or received, net of
transaction costs as appropriate, and subsequently carried at fair value or
amortised cost, as indicated in the tables below. Derivatives are initially
recognised at fair value on the date the contract is entered into and are
subsequently remeasured at their fair value.

The carrying amount of financial assets and liabilities measured at fair value
is principally calculated based on inputs other than quoted prices that are
observable for these financial assets or liabilities, either directly (i.e. as
unquoted prices) or indirectly (i.e. derived from prices). Where no price
information is available from a quoted market source, alternative market
mechanisms or recent comparable transactions, fair value is estimated based on
the Group's views on relevant future prices, net of valuation allowances to
accommodate liquidity, modelling and other risks implicit in such estimates.

The inputs used in fair value calculations are determined by the relevant
segment or function. The functions support the assets and operate under a
defined set of accountabilities authorised by the Executive Leadership Team.
Movements in the fair value of financial assets and liabilities may be
recognised through the income statement or in other comprehensive income.

For financial assets and liabilities carried at fair value, the Group uses the
following to categorise the method used:

Fair value hierarchy  Level 1                 Level 2                           Level 3
--------------------- ----------------------- --------------------------------- -------------------------

                      (unadjusted) in active  prices included within Level 1    observable in the market
                      markets for identical   that are observable for the       using appropriate
                      financial assets and    financial asset or liability,     valuation models,
                      liabilities.            either directly (i.e. as unquoted including discounted cash
                                              prices) or indirectly (i.e.       flow modelling.
                                              derived from prices).

The financial assets and liabilities are presented by class in the tables below
at their carrying values, which generally approximate to fair value. In the case
of US$3,019 million (30 June 2017: US$3,019 million) of fixed rate debt not
swapped to floating rate, the fair value at 31 December 2017 was US$3,684
million (30 June 2017: US$3,523 million) included within Notes and debentures in
the table below.

For financial instruments that are carried at fair value on a recurring basis,
the Group determines whether transfers have occurred between levels in the
hierarchy by reassessing categorisation (based on the lowest level input that is
significant to the fair value measurement as a whole) at the end of each
reporting period. There were no transfers between categories during the period.

For financial instruments not valued at fair value on a recurring basis, the
Group uses a method that is categorised as Level 2.

                     BHP Results for the half year         41
                     ended 31 December 2017

9. Financial risk management - Fair values (continued)

Sensitivity of level 3 financial assets and liabilities

Financial instruments categorised as level 3 are shares and other investments
available for sale and other derivative contracts with a carrying net amount of
US$348 million (30 June 2017: US$435 million). Significant items are derivatives
embedded in physical commodity purchase and sales contracts of gas in Trinidad
and Tobago with a net assets fair value of US$272 million (30 June 2017: US$370
million).

The potential effect of using reasonably possible alternative assumptions in
these models, based on a change in the most significant input, commodity prices,
by an increase/(decrease) of 10 per cent while holding all other variables
constant will increase/(decrease) profit after taxation by US$50 million (30
June 2017: US$62 million).

10. Significant events - Samarco dam failure

On 5 November 2015, the Samarco Mineracao S.A. (Samarco) iron ore operation in
Minas Gerais, Brazil, experienced a tailings dam failure that resulted in a
release of mine tailings, flooding the communities of Bento Rodrigues, Gesteira
and Paracatu and impacting other communities downstream (the Samarco dam
failure).

Samarco is jointly owned by BHP Billiton Brasil Ltda (BHP Billiton Brasil) and
Vale S.A. (Vale). BHP Billiton Brasil's 50 per cent interest is accounted for as
an equity accounted joint venture investment. BHP Billiton Brasil does not
separately recognise its share of the underlying assets and liabilities of
Samarco, but instead records the investment as one line on the balance sheet.
Each period, BHP Billiton Brasil recognises its 50 per cent share of Samarco's
profit or loss and adjusts the carrying value of the investment in Samarco
accordingly. Such adjustment continues until the investment carrying value is
reduced to US$ nil, with any additional share of Samarco losses only recognised
to the extent that BHP Billiton Brasil has an obligation to fund the losses, or
when future investment funding is provided. After applying equity accounting,
any remaining carrying value of the investment is tested for impairment.

Any charges relating to the Samarco dam failure incurred directly by BHP
Billiton Brasil or other BHP entities are recognised 100 per cent in the Group's
results.

The financial impacts of the Samarco dam failure on the Group's income
statement, balance sheet and cash flow statement for the half year ended 31
December 2017 are shown in the table below and have been treated as an
exceptional item.

Equity accounted investment in Samarco

BHP Billiton Brasil's investment in Samarco remains at US$ nil. BHP Billiton
Brasil provided US$50 million funding under a working capital facility during
the period and recognised additional share of losses of US$50 million. No
dividends have been received by BHP Billiton Brasil from Samarco during the
period. Samarco currently does not have profits available for distribution and
is legally prevented from paying previously declared and unpaid dividends.

10. Significant events - Samarco dam failure (continued)

Dam failure provisions and contingencies

As at 31 December 2017, provisions and contingent liabilities for BHP Billiton
Brasil are not materially different from those disclosed in note 3 'Significant
events - Samarco dam failure' in the 30 June 2017 Annual Report, subject to the
updates set out below:

Environment and socio-economic remediation

Framework Agreement

On 2 March 2016, BHP Billiton Brasil, together with Samarco and Vale, entered
into a Framework Agreement with the Federal Government of Brazil, the states of
Espirito Santo and Minas Gerais and certain other public authorities to
establish a foundation (Fundacao Renova) that will develop and execute
environmental and socio-economic programs to remediate and provide compensation
for damage caused by the Samarco dam failure.

Mining and processing operations remain suspended following the dam failure.
Samarco is currently progressing plans to resume operations, however,
significant uncertainties surrounding the nature and timing of ongoing future
operations remain. In light of these uncertainties and based on currently
available information, at 31 December 2017, BHP Billiton Brasil has recognised a
provision of US$1.0 billion before tax and after discounting (30 June 2017:
US$1.1 billion), in respect of its potential obligations under the Framework
Agreement.

The measurement of the provision requires the use of estimates and assumptions
and may be affected by, among other factors, potential changes in scope of work
and funding amounts required under the Framework Agreement including further
technical analysis required under the Preliminary Agreement, the outcome of the
ongoing negotiations with the Federal and State Prosecutors, costs incurred in
respect of programs delivered, resolution of uncertainty in respect of
operational restart, updates to discount and foreign exchange rates, resolution
of existing and potential legal claims and the status of the Framework
Agreement. As a result, future actual expenditures may differ from the amounts
currently provided and changes to key assumptions and estimates could result in
a material impact to the amount of the provision in future reporting periods.

For the half year ended 31 December 2017, BHP Billiton Brasil has paid US$154
million to allow for the continuation of reparatory and compensatory programs in
relation to the Framework Agreement and a further US$2 million for dam
stabilisation, with the total US$156 million offset against the provision for
the Samarco dam failure.

On 22 December 2017, BHP Billiton Brasil announced a further US$133 million to
support Fundacao Renova, in the event Samarco does not meet its funding
obligations under the Framework Agreement. Any support to the Fundacao Renova
provided by BHP Billiton Brasil will be offset against the provision for the
Samarco dam failure.

Preliminary Agreement

On 18 January 2017, BHP Billiton Brasil together with Samarco and Vale, entered
into a Preliminary Agreement with the Federal Prosecutors' Office in Brazil,
which outlines the process and timeline for further negotiations towards a
settlement regarding the R$20 billion (approximately US$6 billion) Public Civil
Claim and R$155 billion (approximately US$47 billion) Federal Public Prosecution
Office claim relating to the dam failure.

The Preliminary Agreement provides for the appointment of experts to advise the
Federal Prosecutors in relation to social and environmental remediation and the
assessment and monitoring of programs under the Framework Agreement. The expert
advisors' conclusions will be considered in the negotiation of a final
settlement arrangement with the Federal Prosecutors.

Under the Preliminary Agreement, BHP Billiton Brasil, Samarco and Vale agreed
interim security (Interim Security) comprising R$1.3 billion (approximately
US$395 million) in insurance bonds, R$100 million (approximately US$30 million)
in liquid assets, a charge of R$800 million (approximately US$240 million) over
Samarco's assets, and R$200 million (approximately US$60 million) to be
allocated within the next four years through existing Framework Agreement
programs in the Municipalities of Barra Longa, Rio Doce, Santa Cruz do Escalvado
and Ponte Nova.

The Interim Security was provided to the 12th Civil/Agricultural Federal Court
of Minas Gerais on 24 January 2017 and will remain in place until the earlier of
20 April 2018 and the date that a settlement arrangement is agreed between the
Federal Prosecutors, BHP Billiton Brasil, Samarco and Vale.

10. Significant events - Samarco dam failure (continued)

On 16 November 2017, BHP Billiton Brasil, together with Samarco and Vale,
entered into an Amendment Agreement with the Federal Prosecutors' Office in
Brazil (Federal Prosecutors) and the Minas Gerais State Prosecutors Office
(State Prosecutors). The Amendment Agreement amends the Preliminary Agreement by
providing for the State Prosecutors to become party to the Preliminary
Agreement, in addition to including provisions for additional community
consultation and replacing one of the socioeconomic experts appointed in the
Preliminary Agreement to advise the Federal Prosecutors.

In light of the ongoing negotiations, BHP Billiton Brasil, Samarco and Vale,
together with the Federal and State Prosecutors, requested, and the 12th
Civil/Agricultural Federal Court of Minas Gerais approved, an extension to the
date for negotiations towards a settlement agreement in relation to the R$20
billion (approximately US$6 billion) public civil claim and R$155 billion
(approximately US$47 billion) Federal Public Prosecution Office claim to 20
April 2018. During the extension period, the Interim Security and the current
suspension of legal proceedings and injunctions under the Preliminary Agreement
(see below) will remain in place. The parties will use best efforts to achieve a
partial settlement agreement, focused mainly on including prosecutor and
community participation into the governance structure of the Framework
Agreement, by 20 April 2018.

Legal

The following matters are disclosed as contingent liabilities:

BHP Billiton Brasil is among the companies named as defendants in a number of
legal proceedings initiated by individuals, non-governmental organisations
(NGOs), corporations and governmental entities in Brazilian federal and state
courts following the Samarco dam failure. The other defendants include Vale,
Samarco and the Foundation. The lawsuits include claims for compensation,
environmental rehabilitation and violations of Brazilian environmental and other
laws, among other matters. The lawsuits seek various remedies, including
rehabilitation costs, compensation to injured individuals and families of the
deceased, recovery of personal and property losses, moral damages and injunctive
relief. It is not possible at this time to provide a range of possible outcomes
or a reliable estimate of potential future exposures for BHP Billiton Brasil.

In addition, governmental inquiries and investigations relating to the Samarco
dam failure have been commenced by numerous agencies of the Brazilian government
and are ongoing.

Ultimately, all legal matters disclosed as contingent liabilities could have a
material adverse impact on BHP's business, competitive position, cash flows,
prospects, liquidity and shareholder returns.

As at 31 December 2017, contingent liabilities for BHP Billiton Brasil are not
materially different from those disclosed in note 3 'Significant events -
Samarco dam failure' in the 30 June 2017 Annual Report, subject to the updates
set out below:

R$20 billion Public Civil claim

Among the claims brought against BHP Billiton Brasil, is a public civil claim
commenced by the Federal Government of Brazil, states of Espirito Santo, Minas
Gerais and other public authorities on 30 November 2015, seeking the
establishment of a fund of up to R$20 billion (approximately US$6 billion) in
aggregate for clean-up costs and damages.

While a final decision by the 12th Civil/Agricultural Federal Court of Minas
Gerais on the issue of ratification of the Framework Agreement is pending, the
Preliminary Agreement suspends a R$1.2 billion (approximately US$360 million)
injunction order under the R$20 billion Public Civil Claim.

The Preliminary Agreement also requests suspension of the R$20 billion
(approximately US$6 billion) Public Civil Claim with a decision from the Court
pending.

The R$1.2 billion (approximately US$360 million) injunction order may be
reinstated if a settlement arrangement is not agreed by 20 April 2018.

Given the status of these proceedings, it is not possible at this time to
provide a range of possible outcomes or a reliable estimate of potential future
exposures for BHP Billiton Brasil.

10. Significant events - Samarco dam failure (continued)

Federal Public Prosecution Office claim

BHP Billiton Brasil is among the defendants named in a claim brought by the
Federal Public Prosecution Office on 3 May 2016, seeking R$155 billion
(approximately US$47 billion) for reparation, compensation and moral damages in
relation to the Samarco dam failure.

With regard to the Preliminary Agreement, the 12th Civil/Agricultural Federal
Court of Minas Gerais suspended the Federal Public Prosecution Office claim,
including a R$7.7 billion (approximately US$2.3 billion) injunction request.
However, proceedings may be resumed if a settlement arrangement is not agreed by
20 April 2018. Given the status of these proceedings, it is not possible at this
time to provide a range of possible outcomes or a reliable estimate of potential
future exposures for BHP Billiton Brasil.

Class action complaint - shareholders

In February 2016, a putative class action complaint (Complaint) was filed in the
U.S. District Court for the Southern District of New York on behalf of
purchasers of American Depository Receipts of BHP Billiton Ltd and BHP Billiton
Plc between 25 September 2014 and 30 November 2015 against BHP Billiton Ltd and
BHP Billiton Plc and certain of its current and former executive officers and
directors. The Complaint asserts claims under U.S. federal securities laws and
indicates that the plaintiffs will seek certification to proceed as a class
action.

The amount of damages sought by the plaintiffs on behalf of the putative class
is unspecified. On 14 October 2016, the defendants moved to dismiss the
Complaint. In a decision of the District Court dated 28 August 2017, the claims
were dismissed in part, including the claims against the current and former
executive officers and directors.

Given the preliminary status of this matter, it is not possible at this time to
provide a range of possible outcomes or a reliable estimate of potential future
exposures to BHP Billiton Ltd and BHP Billiton Plc.

Class action complaint - bond holders

On 14 November 2016, a putative class action complaint (Complaint) was filed in
the U.S District Court for the Southern District of New York on behalf of all
purchasers of Samarco's ten-year bond notes due 2022-2024 between 31 October
2012 and 30 November 2015 against Samarco and the former chief executive officer
of Samarco. The complaint asserts claims under the U.S. federal securities laws
and indicates that the plaintiff will seek certification to proceed as a class
action.

On 6 March 2017, the Complaint was amended to include BHP Billiton Ltd, BHP
Billiton Plc, BHP Billiton Brasil Ltda and Vale S.A. and officers of Samarco,
including four of Vale S.A. and BHP Billiton Brasil Ltda's nominees to the
Samarco Board. On 5 April 2017, the plaintiff dismissed the claims against the
individuals. The remaining corporate defendants filed a joint motion to dismiss
the Complaint on 26 June 2017. That motion is pending before the Court.

The amount of damages sought by the plaintiff on behalf of the putative class is
unspecified. Given the preliminary status of this matter, it is not possible at
this time to provide a range of possible outcomes or a reliable estimate of
potential future exposures to BHP Billiton Ltd, BHP Billiton Plc and BHP
Billiton Brasil Ltda.

Criminal charges

The Federal Prosecutors' Office has filed criminal charges against BHP Billiton
Brasil, Samarco and Vale and certain employees and former employees of BHP
Billiton Brasil (Affected Individuals), Vale and Samarco in the Federal Court of
Ponte Nova, Minas Gerais. On 3 March 2017, BHP Billiton Brasil filed its
preliminary defences. BHP Billiton Brasil rejects outright the charges against
the company and the Affected Individuals and will defend the charges and fully
support each of the Affected Individuals in their defence of the charges.

Under the criminal charges against BHP Billiton Brasil, Vale and Samarco and
certain of the individuals, a R$20 billion (approximately US$6 billion) asset
freezing order application was made by the Federal Prosecutors. In July 2017,
the Federal Court of Ponte Nova denied the Federal Prosecutors' application for
an asset freezing order.

Given the status of this matter, it is not possible at this time to provide a
range of possible outcomes or a reliable estimate of potential future exposures
for BHP Billiton Brasil.

10.  Significant events - Samarco dam failure (continued)

Other claims

Additional lawsuits and government investigations relating to the Samarco dam
failure may be brought against BHP Billiton Brasil and possibly other BHP
entities in Brazil or other jurisdictions.

BHP's and BHP Billiton Brasil's potential liabilities, if any, resulting from
other pending and future claims, lawsuits and enforcement actions relating to
the Samarco dam failure, together with the potential cost of implementing
remedies sought in the various proceedings, cannot be reliably estimated at this
time and therefore a provision has not been recognised and nor has any
contingent liability been quantified for such matters.

BHP Insurance

BHP has third party liability insurance for claims related to the Samarco dam
failure made directly against BHP Billiton Brasil or other BHP entities.
External insurers have been advised of the Samarco dam failure and a formal
claim has been prepared and submitted. At 31 December 2017, an insurance
receivable has not been recognised for any potential recoveries under insurance
arrangements.

Commitments

Under the terms of the Samarco joint venture agreement, BHP Billiton Brasil does
not have an existing obligation to fund Samarco. For the half year ended 31
December 2017, BHP Billiton Brasil has provided US$50 million funding to support
Samarco's operations and a further US$2 million for dam stabilisation, with
undrawn amounts of US$24 million expiring as at 31 December 2017.

On 22 December 2017, BHP Billiton Brasil announced a new short-term facility of
up to US$48 million to carry out ongoing repair works, maintain Samarco's
facilities and support restart planning. Funds will be released to Samarco only
as required and subject to the achievement of key milestones with amounts
undrawn expiring at 30 June 2018.

Any additional requests for funding or future investment provided would be
subject to a future decision, accounted for at that time.

11. Impairment of non-current assets - Onshore US

The Group is currently progressing a number of alternatives to exit our Onshore
US assets for value. In light of this process, and the significant management
judgement required when assessing the recoverable amount of assets, this note
provides an update on the Group's assessment of the recoverability of the
Onshore US assets.

Carrying amount

For impairment testing purposes, the goodwill arising from the Petrohawk
acquisition in August 2011 is allocated to the Onshore US group of cash
generating units (CGUs) which includes the Permian, Haynesville, Fayetteville,
Black Hawk and Hawkville CGUs. The carrying amount of the Onshore US group of
CGUs for impairment purposes is determined on a basis consistent with the way
the recoverable amount is determined and comprises:

                                                                           31 Dec 2017 30 June 2017
                                                                              US$M        US$M
                                                                           ----------- ------------

Impairment testing requirements

Impairment tests are carried out annually for goodwill. In addition, impairment
tests for all assets and CGUs are performed when there is an indication of
impairment. If the carrying amount of the asset or CGU exceeds its recoverable
amount, the asset or CGU is impaired and an impairment loss is charged to the
income statement so as to reduce the carrying amount to its recoverable amount.

--------------------------------------------------------------------------------
                     BHP Results for the half year         47
                     ended 31 December 2017

11. Impairment of non-current assets - Onshore US (continued)

Previously impaired assets and CGUs (excluding goodwill) are reviewed for
possible reversal of previous impairment at each reporting date. Impairment
reversal cannot exceed the carrying amount that would have been determined (net
of depreciation) had no impairment loss been recognised for the asset or CGU.

At the half year, impairment tests, including for goodwill, are only performed
if there is an indication of an impairment, or impairment reversal, since the
end of the last financial year.

FY2017 Assessment

The annual impairment test of the Onshore US goodwill was performed in June
after an assessment of the individual CGUs that it comprises. The recoverable
amount of Onshore US at 30 June 2017 was calculated using fair value less cost
of disposal (FVLCD) methodology.

The impairment testing at 30 June 2017 resulted in no impairment or reversals of
impairment for Onshore US.

HY2018 Assessment

For HY2018, an assessment was performed to determine whether there were any
indicators of an impairment or impairment reversal since 30 June 2017. This
included consideration of changes to market participant assumptions for the most
significant estimates impacting asset recoverable amount valuations, including:

.   Production - the review of additional production data from BHP's wells and
    third party data did not indicate a significant change to the assumptions
    regarding production volumes;

.   Price - the Group has forecast some decreases in the long run crude oil and
    natural gas prices from the forecasts used at 30 June 2017. However,
    sensitivities performed on internal valuations for these changes did not
    give rise to an indicator of impairment; and

.   Discount rate - no indicators have arisen since 30 June 2017 that would
    indicate a significant change to the real post-tax rate of 7.0 per cent.

The enactment of the TCJA in the US on 22 December 2017 is expected to have a
positive impact on the fair values of the Onshore US assets, largely due to the
reduction in the rate of US corporate income tax. Ongoing analysis is being
performed to assess the longer term potential impact of the TCJA on price
forecasts, supply costs and the cost of capital.

Overall, the Group has assessed that there have been no changes that would
indicate an impairment or impairment reversal since 30 June 2017. Accordingly, a
recoverable amount determination at 31 December 2017 was not required to be
performed.

Key judgements and estimates

In determining the recoverable amount of assets, in the absence of quoted market
prices, estimates are made regarding the present value of future post-tax cash
flows. These estimates require significant management judgement and are subject
to risk and uncertainty that may be beyond the control of the Group. The
estimates are made from the perspective of a market participant and include
prices, future production volumes, operating costs, tax attributes and discount
rates.

The calculation of FVLCD for Onshore US is most sensitive to changes in a market
participant's perspective of crude oil and natural gas prices, production
volumes and discount rates. In our FY2017 financial statements we identified
reasonably possible changes that would result in the estimated recoverable
amount being equal to the carrying amount of Onshore US, including goodwill.

Therefore there is a possibility that changes in circumstances will materially
alter projections, which may impact the recoverable amount of assets at future
reporting dates.

The Group's current divestment timeline includes the opening of data rooms and
the receipt of bids prior to 30 June 2018, with evaluation and negotiation in
the September quarter. Other divestment options continue to be considered. As
the Group progresses alternative exit strategies, this may give rise to new
information relevant to the assumptions used by management in the estimation of
recoverable amount.

12.  Subsequent events

No matters or circumstances have arisen since the end of the financial year
that have significantly affected, or may significantly affect, the operations,
results of operations or state of affairs of the Group in subsequent accounting
periods.

future developments are given on pages 1 to 26. The Review of Operations has
been incorporated into, and forms part of, this Directors' Report.

Principal Risks and Uncertainties

Due to the international scope of the Group's operated and non-operated assets
and the industries in which it is engaged, there are a number of risk factors
and uncertainties which could have an effect on the Group's results and
operations over the next six months. The principal risks affecting the Group are
described on pages 34 to 43 of the Group's Annual Report for the year ended 30
June 2017 (a copy of which is available on the Group's website at www.bhp.com)
and are summarised below. There are no material changes in those risk factors
for the remaining six months of the financial year except to the extent
described in note 10 'Significant events - Samarco dam failure' of the half year
financial statements and the 'Outlook' section.

                                        member firm of the KPMG network of
                                        independent member firms affiliated with

Independent Review Report

Independent Auditors' review report of KPMG LLP ('KPMG UK') to the members of
BHP Billiton Plc and of KPMG ('KPMG Australia') to the members of BHP Billiton
Limited

Conclusions

For the purposes of these reports, the terms 'we' and 'our' denote KPMG UK in
relation to UK responsibilities and reporting obligations to the members of BHP
Billiton Plc, and KPMG Australia in relation to Australian responsibilities and
reporting obligations to the members of BHP Billiton Limited.

BHP ('the Group') consists of BHP Billiton Plc, BHP Billiton Limited and the
entities they controlled during the half year ended 31 December 2017.

We have reviewed the accompanying condensed financial statements of the Group
for the half year ended 31 December 2017 ('half year financial statements'),
which comprise the Consolidated Income Statement, Consolidated Statement of
Comprehensive Income, Consolidated Balance Sheet, Consolidated Cash Flow
Statement, Consolidated Statement of Changes in Equity, Notes 1 to 12 comprising
a summary of significant accounting policies and other explanatory information.
KPMG Australia considers the Directors' Declaration to be part of the half year
financial statements when forming its conclusion.

Review conclusion by KPMG UK

Based on our review, nothing has come to our attention that causes us to believe
that the half year financial statements for the six months ended 31 December
2017 are not prepared, in all material respects, in accordance with IAS 34
'Interim Financial Reporting', as adopted by the European Union ('EU'), and the
Disclosure Guidance and Transparency Rules ('the DTR') of the United Kingdom's
Financial Conduct Authority ('the UK FCA').

Review conclusion by KPMG Australia

Based on our review, which is not an audit, we have not become aware of any
matter that makes us believe that the half year financial statements, including
the Directors' Declaration, of the Group are not in accordance with the
Australian Corporations Act 2001, including:

a)  Giving a true and fair view of the Group's financial position as at 31
    December 2017 and of its performance for the half year ended on that date;
    and

b)  Complying with Australian Accounting Standard AASB 134 'Interim Financial
    Reporting' and the Australian Corporations Regulations 2001.

Scope of review

KPMG UK conducted its review in accordance with International Standard on Review
Engagements (UK and Ireland) 2410 'Review of Interim Financial Information
Performed by the Independent Auditor of the Entity' ('ISRE 2410') issued by the
Auditing Practices Board for use in the UK. We read the other information
contained in the half year financial report and consider whether it contains any
apparent misstatements or material inconsistencies with the information in the
half year financial statements.

KPMG Australia conducted its review in accordance with Auditing Standard on
Review Engagements ASRE 2410 'Review of a Financial Report Performed by the
Independent Auditor of the Entity' ('ASRE 2410'), as issued by the Australian
Auditing and Assurance Standards Board. As the auditor of BHP Billiton Limited,
ASRE 2410 requires that KPMG Australia complies with the ethical requirements
relevant to the audit of the annual consolidated financial statements.

A review of half year financial statements consists of making enquiries,
primarily of persons responsible for financial and accounting matters, and
applying analytical and other review procedures. A review is substantially less
in scope than an audit conducted in accordance with auditing standards and
consequently does not enable us to obtain assurance that we would become aware
of all significant matters that might be identified in an audit. Accordingly, we
do not express an audit opinion.

Directors' responsibilities

The Directors are responsible for preparing the half year financial report which
gives a true and fair view in accordance with:

.   The DTR of the UK FCA, and under those rules, in accordance with IAS 34
    'Interim Financial Reporting' as adopted by the EU; and

.   Australian Accounting Standards and the Australian Corporations Act 2001 and
    for such internal control as the Directors determine is necessary to enable
    the preparation of the half year financial statements that are free from
    material misstatement, whether due to fraud or error; selecting and applying
    appropriate accounting policies; and making accounting estimates that are
    reasonable in the circumstances.

Respective responsibilities of KPMG UK and KPMG Australia

KPMG UK's responsibility is to express a conclusion on the half year financial
statements in the half year financial report based on our review.

KPMG Australia's responsibility is to express a conclusion on the half year
financial statements, including the Directors' Declaration based on our review.

The purpose of our review work and to whom we owe our responsibilities

KPMG UK's report is made solely to BHP Billiton Plc's members, as a body, in
accordance with the terms of KPMG UK's engagement to assist BHP Billiton Plc in
meeting the requirements of the DTR of the UK FCA.

KPMG Australia's report is made solely to BHP Billiton Limited's members, as a
body, in accordance with the Australian Corporations Act 2001. KPMG Australia
has performed an independent review of the half year financial statements,
including the Directors' Declaration, in order to state whether, on the basis of
the procedures described, it has become aware of any matter that makes KPMG
Australia believe that the half year financial statements, including the
Directors' Declaration, are not in accordance with the Australian Corporations
Act 2001 including: giving a true and fair view of the Group's financial
position as at 31 December 2017 and its performance for the half year ended on
that date; and complying with Australian Accounting Standard AASB 134 'Interim
Financial Reporting' and the Australian Corporations Regulations 2001.

Our review work has been undertaken so that we might state to the members of
each BHP Billiton Plc and BHP Billiton Limited those matters we are required to
state to them in this report, and the further matters we are required to state
to them in accordance with the terms agreed with each company, and for no other
purpose. Accordingly, each of KPMG UK and KPMG Australia makes the following
statement: to the fullest extent permitted by law, we do not accept or assume
responsibility to anyone other than the company and the company's members as a
body, for our review work, for our report, or for the conclusions we have
reached.
