Coal industry groups are warning of further job cuts, with the sector caught off guard by continued price weakness.
The Australian Coal Association says the dramatic slump in global commodity prices, which has prompted thousands of job losses around the country, caught the industry off guard.
It is estimated more than 7,500 jobs have been lost in the sector this year, with the bulk of those in Queensland, as resources firms cut spending by closing mines and shelving projects.
The Coal Association's chief executive Nikki Williams says, while commodity prices are cyclical, no one was prepared for the breakneck pace of the latest slump.
"What is unprecedented is the speed of the price drop and the ramp up in costs and that price crunch," she said.
"Literally it was like going off a cliff.
It just happened very quickly - a very steep decline - it was not a slowing down of the cycle which you've typically seen in many past cycles." Queensland's Resources Council is warning of more job losses in the coal industry, with mining companies continuing to close mines and postpone projects to save money.
The Resources Council's executive director Michael Roche has told Radio National mining firms feel things are even worse now than they were during the global financial crisis.
"It is a perfect storm because at the time of the GFC costs weren't as high," he said.
"So costs have got out of control in the industry, and then we've had the added burden of an Aussie dollar stubbornly well above parity, and then governments come along from 1 July with the carbon tax, and then from 1 October in Queensland, higher royalties."
