Protesters have ambushed the LNP leader Tim Nicholls at a private debate, after spending hours hiding under a platform in wait for him.

Mr Nicholls had just started addressing a forum in Townsville about infrastructure projects, when the anti-Adani protesters ran onto the stage, shouting at the crowd.

Protesters against the Adani mining project in north Queensland have heckled and tried to disrupt a number of events attended by Premier Annastacia Palaszczuk and Mr Nicholls during the election campaign.

The group of four at today's forum had been hiding for hours under a platform set up for media equipment at the back of the room.

The activists shouted "We're here to remind you there are no jobs on a dead planet," and "The reef is dying," before they were taken away by security and police.

Mr Nicholls said he was not too fazed by the disruption.

"It's just hurley-burley of Queensland politics," he said.

"It doesn't worry me — I think the only thing is they were pretty hot and smelly after hiding for three hours underneath you good folk in the media.

"They've got their point of view, I don't agree with it.

"I just think they were bloody rude to be frank."

The forum was a ticketed event with addresses also made by One Nation's Queensland leader Steve Dickson and Robbie Katter from Katter's Australian Party.

While Mr Nicholls said he did not view the ambush as a security issue, Townsville Police confirmed they would be reviewing how the group hid for hours undetected.

"If that did occur then that would be subject to a review of how security was managed for the event," Inspector Damien Crosby said.

"Everyone has a right to peacefully protest, but that right doesn't extend to committing trespass offences of interfering with a peaceful event.

"And on this occasion they were removed from the premises and move on directions and breach of the peace action was taken."

Ms Palaszczuk did not attend the forum in Townsville because of a previous commitment.

Premier downplays MP's embrace of Hanson

Ms Palaszczuk has been visiting Bundaberg today where she has tried to shrug off the conflicting signals sent yesterday when Labor MP Jo-Ann Miller warmly embraced Pauline Hanson at a pre-polling booth.

A day after the Ipswich encounter, Ms Palaszczuk said she had been too busy to talk to the Bundamba MP but still insisted that One Nation policies would be chaotic for Queensland.

Ms Palaszczuk denied there was any contradiction, or that Ms Miller had thumbed her nose at her.

"No not at all. She made it very clear she backs my clear position about no deals with One Nation," Ms Palaszczuk said.

But there's been no conversation between the Labor leader and the maverick member, "because she's out campaigning just like I am," Ms Palaszczuk said.

"I have been busy campaigning, all right?

"We addressed this yesterday, and like I said there is nothing wrong with people showing common decency to other people. OK?"

Contrary to suggestions that the Miller-Hanson meeting had been orchestrated, Ms Palaszczuk said she had been advised it was a chance encounter.

"That's what I was told, I looked at the coverage, I looked at what everyone else was saying and that's what I was advised," she said.

Clearly frustrated by the line of questioning, Ms Palaszczuk dismissed any damage to her anti-One Nation theme.

"I reject that. I reject that outright.

"The real issue here is what is going to happen in three days time on Saturday. That is the fundamental issue."

From Bundaberg, Ms Palaszczuk set off by bus for Maryborough.

She also promised $14 million over four years to help build walking, cycling and horse-riding trails on disused rail corridors.
