Gina Rinehart's Alpha coal mine has been given the go ahead after the Land Court upheld prior governmental approvals.
However, it it dependent wholly on the condition that it obtains licences to use and take water under the Water Act, otherwise, the Land Court stated that the mine should be rejected outright.
This latest announcement may be a massive win for Rinehart, following her Roy Hill iron ore mine securing billions of dollars in funding for its development.
The upholding of the original government approvals - dependent on groundwater issues - for the joint venture between Rinehart's Hancock Coal and GVK was welcomed by the company.
One of the major hurdles for the approval of the project was environmental concerns, with GVK Hancock saying that "during the case, objections were heard in relation to climate change, economics, surface water, groundwater, land use, public interest, and greenhouse gas emissions," it said in a company statement.
"In its judgment the Land Court clearly confirmed that GVK Hancock's comprehensive environmental assessment addressed all the objections raised with no requirement for further conditions apart from ground water," a company spokesperson said.
The announcement was also welcomed by the Queensland Resources Council.
"This kind of development is a game changer for [Queensland's] central west in addressing a long term decline in the region's fortune," QRC's head Michael Roche said.
The approval by the Land Court also represents the first steps in the QLD government's proposal to address objections to major projects in the state.
The Alpha Coal project will employ around 7500 people across the Galilee Basin region during construction, and close to 4000 once in operation, contributing approximately $40 billion in taxes and royalties over the life of the mine.
