Queensland's Cabinet has agreed Adani will pay full royalties for its Carmichael coal mine in central Queensland.

Cabinet Ministers met today and discussed the issue.

Premier Annastacia Palaszczuk said they had reached an agreement.

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

"The Adani Carmichael mine will pay every cent of royalties in full."

The Cabinet decision allows for the possibility of a royalty deferral in the first few years, but Adani would have to eventually pay in full and with interest.

This evening's decision applies to all future developments in the Galilee and Surat basins and the North West Mineral Province.

Earlier this month, the ABC revealed the Government was actively considering giving Adani a discount on royalties for the Indian mining giant.

It was expected to have cost up to $320 million in lost revenue to the state.

An Adani Australia spokesman said the company would give urgent consideration to Cabinet's decision.

"Adani will analyse the details when they have been formally provided," the spokesman said.

"Adani confirms again that it will pay every cent of royalties to the state as was always the case, and that it also remains committed to regional Queensland and generating 10,000 direct and indirect jobs."

Earlier this week Adani announced it would postpone its final investment decision on the $16.5 billion project until the State Government gave "clarity" over royalties.
