THE Greens will move to give farmers veto powers over coal-seam gas operations on their land after seizing on comments from Tony Abbott, who last week backed the right of farmers to deny miners access to their properties.
After the Opposition Leader declined on Saturday to elaborate on remarks he made on Friday that farmers had "a right to say no", Greens leader Bob Brown said he would seek Mr Abbott's support for a private member's bill on the issue.
The bill, to be brought into the Senate in the next fortnight by Greens Queensland senator Larissa Waters, would require the written permission of landholders be obtained before companies could explore for, or extract, coal-seam gas.
As senior Coalition figures accused Senator Brown of trying to wedge the Coalition on the issue, which pits its rural constituency against the mining industry, Mr Abbott's spokesman said he "stands by his recent comments that the Coalition supports a vibrant coal-seam gas industry".
"However, expansion of coal-seam gas should be in harmony with the rights of landholders and the protection of prime agricultural land for food production in the years ahead," he said.
"Issues related to land use are primarily a matter for the states and the Coalition has no intention of changing this.
"If Bob Brown has a different view, he should be talking to his 'co-prime minister', Julia Gillard, and Labor."
But Resources Minister Martin Ferguson accused Mr Abbott of risking the $45 billion of investment in the Queensland industry through his comments on Friday and of dodging questions on the issue in Perth on Saturday.
He said Mr Abbott was a "rank opportunist" and an "economic vandal".
"Mr Abbott's comments jeopardise future investment, raise the spectre of sovereign risk and are contrary to Australia's policy of welcoming foreign investment -- a policy that has in no small way helped ensure the fundamental strength of our economy," Mr Ferguson said.
"Two of the major companies operating in the coal-seam gas industry -- Santos and Origin -- are Australian companies. Is Mr Abbott saying to other major companies in the energy sector, like British Gas or Chevron with their $43bn Gorgon project, that their investment is not welcome?"
The Greens move comes amid rising anger over coal-seam gas extraction in Queensland and NSW, where the rapid expansion of the industry has sparked protests amid concerns about the industry's impact on prime agricultural land and its effect on ground water reserves.
Concern over the issue has sparked a Senate inquiry and on Friday Mr Abbott told Sydney radio host Alan Jones: "If you don't want something to happen on your land, you ought to have a right to say no. Now, OK, under certain circumstances the government ought to be able to resume your land, but it's got to be done at a fair price."
While "reputable miners" would not intrude without permission, Mr Abbott said, "people are entitled to be concerned about any situation where miners are coming on to land against the wishes of landholders".
Senator Brown said he had written to Mr Abbott and Nationals Senate leader Barnaby Joyce to "move our common position forward as quickly as possible".
"Queensland's new Greens senator Larissa Waters' bill will use the corporations power in the Constitution to require coal-seam gas corporations to get written permission before entering a farmer's land," Senator Brown said.
"It is a simple solution to the growing alarm in rural Australia where, on the fertile Darling Downs alone, more than 40,000 drill holes to extract gas are proposed in the coming years.
"We would like to extend the bill to include open-cut coalmines but feel that, at this juncture, we'd be better to confine legislation to the terms set by Mr Abbott."
But the Australian Petroleum, Production and Exploration Association's chief operating officer for eastern Australia, Rick Wilkinson, said: "Unfortunately, it is not surprising to see the Greens seek to benefit from increasing sovereign risk.
"But what is truly remarkable and hypocritical is that they choose to do so by opposing a fuel source that is up to 70 per cent cleaner than coal."
West Australian Premier Colin Barnett weighed into the debate yesterday, saying coal-seam gas mining would be one of the biggest environmental issues to confront the country, while backing the need for mining companies to respect the rights of farmers.
Addressing the debate over whether farmers should be able to say no to mining on their land, Mr Barnett said the extraction of unconventional gas had a significant impact on the environment.
"The situation in Queensland is where the extraction of tight gas does have a significant impact visually and some very complex and risky environmental impacts on water tables. I think it will probably be one of the big environmental issues facing Australia.
