Increased production at WA mines has significantly contributed to a record $175 billion worth of resources and energy exports from Australia, a new government report shows.

Iron ore projects in the Pilbara led the way, with total export earnings of the commodity increasing by 56 per cent to $54 billion, according to the Bureau of Resources and Energy Economics report.

The bureau said the increase was aided by a combination of higher export volumes, particularly from Rio Tinto and BHP Billiton mines in the Pilbara, and higher contract prices.

WA's Boddington gold mine, operated by Newmont, contributed to the majority of the nation's 11 per cent increase in gold production, to 266 tonnes.
