March 29 (Reuters) – Australian shares edged up on Monday, as higher commodity prices lifted miners and energy stocks on worries that global supplies of crude and refined products could be disrupted for weeks as workers try to dislodge a container blocking the Suez Canal.

Also lifting risk appetite was a report on Monday that showed the country is expecting to log a record A$136 billion ($103.85 billion) from iron ore exports this financial year in signs of a global steelmaking recovery from the pandemic-led downturn.
Copper prices rose in the previous session as markets worried about the cost repercussions for transporting industrial metals following the Suez Canal blockage.
The mining sub-index jumped nearly 2% in its biggest intraday percentage gain in more than two weeks. Rio Tinto and BHP Group, which have significant copper mining operations, rose as much as 2% and 2.3%, respectively.
