Activists have stormed the stage during a leaders debate in Townsville to protest against Adani's proposed Carmichael megamine.

The group of Stop Adani protesters emerged from hiding places under an audio-visual stage at The Ville Resort- Casino after Opposition Leader Tim Nicholls began his speech.

The group made it to the stage, yelling and waving banners before they were removed by security.

It came after Townsville Enterprise chief executive officer Patricia O'Callaghan said earlier at the breakfast she disagreed with Annastacia Palaszczuk's decision to veto a NAIF loan to Adani.

Ms O'Callaghan said recently during an interview with a southern radio station on the Adani veto, she was pitted against a Greens candidate.

"When the Greens representative talked about how this was a win for their party, my heart broke for the thousands of people who registered for those jobs with Adani," she said.

But Mr Nicholls said he wasn't worried about the disruption.

"It's part and parcel of the hurly burly of politics," he said.

"It was just bloody rude to be frank."
