Indian mining giant Adani has deferred making a final investment decision on its controversial Carmichael coal mine after the Queensland government delayed a cabinet discussion over royalty payments on Monday.

Factional wrangling over a so-called "royalties holiday" for Adani has seen the state Labor government put the issue on the back-burner before next month's state budget.

In light of that, an Adani spokesman said the mining company has deferred it's final investment decision, due next Monday, "until cabinet makes a decision".

The Palaszczuk government has been considering a mining industry agreement that could include deferred or reduced royalties.
