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.
