Western Australia Premier Colin Barnett says the state's resources sector will need another 100,000 skilled workers in the future.
Despite mining companies in Queensland and WA slashing jobs Barnett said the resources sector was still set to grow.
ABC News reports Barnett also said the fall in commodity prices would be a temporary problem for the industry.
"Through this decade we expect liquefied natural gas production to treble and we expect iron ore production to double," he said.
"There's probably the need for another 100,000 people to come across into Western Australia and take up jobs."
Earlier this week Pilbara miner Fortescue Metals Group signaled it would cut up to 1,000 jobs to stay profitable.
BHP Billiton has also announced delays to some Pilbara expansions as the falling iron ore price squeezes margins on all producers.
