Most Queenslanders believe the state should block any taxpayer-funded loan to Indian mining giant Adani, a poll suggests.

The Stop Adani alliance commissioned the ReachTEL poll 10 days before Premier Annastacia Palaszczuk announced last week that she would veto any loan to Adani, citing an alleged plan by the LNP to smear her and her partner, who worked on the company's loan application.

The poll of 1652 voters statewide showed 70 per cent did not want Adani to be loaned taxpayer funds from the federal government's Northern Australian Infrastructure Facility (NAIF).

The survey showed opposition to the loan was strong across all parties.
