Answer 2

Western Australia has the highest per capita output of any Australian state, with an economy that has been largely based on the extraction and export of mining and petroleum commodities, especially, iron, alumina, natural gas, nickel and gold. Western Australia is a leading alumina extractor, producing more than 20% of the world's aluminium. It is also the world's third-largest iron ore producer, producing around 15% of the world's total iron ore output. Western Australia also extracts up to 75% of Australia's 240 tonnes of gold. Diamonds are extracted at Argyle in the North West.
