Queensland Premier Annastacia Palaszczuk has called on Indian company Adani to "get on with it" and build its controversial $16.5 billion Carmichael mine rather than wait around for potential federal taxpayer funding.

In a significant hardening of her stance on the Adani mine and rail project, which has dominated the state election campaign, Ms Palaszczuk said the waiting around for financial close on the mega-mine had gone on too long.
