A group of Queensland farming families is launching a last-ditch effort to stop the southern hemisphere's biggest coal mine being built on their land.
The battle over Xstrata's Wandoan project will reach the Supreme Court later this month, when the farmers will argue the State Government should never have approved the mine.
The southern Queensland farmers are also concerned market conditions could delay the project and leave them in limbo.
Xstrata's $7 billion plan includes a 30-year open-cut thermal coal mine, a coal handling and preparation plant and support facilities to help produce 30 million tonnes of coal a year.
John Erbacher's piggery, cattle and mixed cropping operation are all likely to be shut down to make way for the mine.
But after five years of fighting Xstrata, Mr Erbacher says he is not ready to concede defeat.
"You wake up at 2.30 in the morning dreaming of them and wake up with the anxiety attacks," he said.
"I just object to people walking on, saying, 'You've got to go.
We will take your farm' and that was said a number of times." Seventy farming and grazing properties lay inside Xstrata's mining lease area, which covers 32,000 hectares.
Forty-two families reached agreement to sell to the company, but another five remain.
Last year they unsuccessfully challenged the mine in the Land Court, and next week they are asking the court for a judicial review of the state minister's approval.
"I feel aggrieved that the minister has prematurely approved the environmental authority but they assured the Government that they would own all the land so therefore they were given a concession," Mr Erbacher said.
If they fail, they will be forced to stop farming their land and have to accept compensation, which they will use to start again elsewhere.
Limbo But there are reports the mine could be delayed, and Mr Erbacher's family fear they will then be living in limbo.
However, a spokesman for Xstrata told ABC's PM program that compensation will be paid regardless of the construction date.
He also said the company meets the highest environmental standards.
The Wandoan coal project would be a catalyst for other investment, including a railway and other mines.
Other farmers and rural residents who have benefitted from the project welcome mining investment.
The Xstrata coal mine proposes to employ up to 800 people, and for Wandoan gym operator Melanie Lindsay, that means business.
"I think it's brought some great opportunities for young people as well as business owners," she said.
"You have to accept how the community is changing, however you don't ever want to lose how we grew up and what we do with our properties and the rights that we have on our land." The Environment Minister, Andrew Powell, declined to comment ahead of the Supreme Court case.
