Western Australia is home to 111 principal mining projects and hundreds of smaller quarries and mines, producing over 50 different commodities. In 2017, iron ore was the state's most valuable resource, followed by liquefied natural gas; gold; alumina and bauxite; crude oil and condensate; nickel; natural gas; base metals (copper, lead and zinc); tin, tantalum and lithium; and mineral sands (garnet, illmenite, leucoxene, zircon and rutile).

Minerals and petroleum are main industries in Western Australia and output growth is forecast for these sectors in the medium to long term. 

Western Australia is one of the most productive and diversified mineral and petroleum regions in the world, with more than 50 mineral and petroleum products being produced in commercial quantities worth A$108.8 billion in 2017. 

The State leads Australia in minerals and petroleum output and produces a significant proportion of the world’s trade in several key commodities.
