The future of Adani's proposed multibillion-dollar Carmichael coal mine remains under a cloud even after Queensland premier Annastacia Palaszczuk declared her cabinet had secured a late agreement on the royalty regime it would offer the miner.

A snap cabinet meeting called late on Friday unanimously agreed Adani would pay all royalties, the premier said in a statement. Details of the new stance - which would apply to policies in the Galilee and Surat Basins and the North West Minerals Province - would be released in "due course".

"There will be no royalty holiday for the Adani Carmichael mine," Ms Palaszczuk said.

The decision is set to further antagonise the Indian-owned miner after the government split on how much support to offer the mine. Adani said it would analyse the details of the government's arrangements.
