The Australian Government approved the A$16.5bn Carmichael coal mine and rail infrastructure project in the Galilee Basin but imposed 36 conditions to safeguard the surrounding natural resources.
Environment Minister Greg Hunt said that: "A rigorous, open and thorough environmental assessment process was undertaken to take account of the public interest in the project."
The Carmichael project located in the north Galilee Basin in Queensland is being developed by the India-based Adani Group.
The project is being opposed by environmental groups for the impacts it is likely to have on groundwater and on the World Heritage-listed the Great Barrier Reef, in addition to a rise in carbon emissions.

Rio Tinto and BHP Billiton received clearance from the US Congress to swap land with the government, allowing the companies to build a $6bn copper mine in Arizona.
The core of the legislation is exchanging 2,400 acres of land above the copper deposit, which is federally owned, for 5,300 acres of land owned by Resolution Copper that was being used for recreational and conservation, as well as other culturally significant land throughout Arizona.
The companies had already invested more than $1bn on drilling and digging a 1.3-mile shaft on the land, which was opposed by environmental and native American groups.
Initially proposed nine years ago, the land swap was tucked away in the annual defence policy bill passed by the Senate and must now reach President Barack Obama to sign it into law.

The Indian Supreme Court ruled that all of the captive coal mining licences awarded between 1993 and 2010 were illegal.
Of the 328 blocks identified by the government, 218 mining blocks were illegally allocated to both private and government firms without performing competitive bids.
In its verdict, the apex court ruled that the successive governments allotted the mining licences with 'arbitrariness, lack of transparency, lack of objectivity and non-application of mind...gifting away precious resources as largesse'.
Queensland Government rejected Glencore Xstrata's $20bn proposed bauxite mine plan in Cape York, Queensland.
The company, along with a group of land owners, planned to develop the mine, which they believed to have rich bauxite deposits but sensitive environmental aspects and heritage issues caused concerns.
Queensland Deputy Premier Jeff Seeney was reported by The Australian as saying that the proposal was rejected because it would take too long to deliver and may not benefit the local indigenous communities.
