Buderim MP Steve Dickson quits LNP, saying major parties had lost their way Mr Dickson now joins crossbench MPs in Queensland's hung parliament

Mr Dickson now joins crossbench MPs in Queensland's hung parliament Pauline Hanson says Mr Dickson joined One Nation as "he has seen what I have been able to achieve"

The Queensland Opposition MP and former Newman government minister quit the LNP this morning and had also removed references to the LNP from his website.

Mr Dickson, the Member for Buderim, said he believed the major political parties needed to "grow a backbone".

"I've had a choice to make — I'm putting my career on the line today," Mr Dickson said.

"I believe we have to put people before politics.

"This is where we have a chance to step up to the mark to make Queensland a better state, a greater state, because that's what we do as human beings."

Mr Dickson said the biggest issue leading to his defection was the regulation of cannabis for terminally ill patients.

He said the major parties were not acting and had lost their way.

"I've also emailed all of my parliamentary colleagues, and I say to all of them: I'm not the enemy — I want to work with you," he said.

"I want Queensland Parliament to be much more bipartisan and I know that some of you will be upset."

Senator Hanson said "of course this means that Steven now is a One Nation member of state parliament".

"No deal was ever done — I at no stage encouraged him to come across," Senator Hanson said.

"He has seen what I have been able to achieve, and it was through sheer frustration that he did not feel like he was a voice for his electorate and that is why he came to One Nation.

"He is worth something, not just a number."

Senator Hanson said she wanted to give the major parties "hell".

"They won't know what happened to them — I've got good strong candidates and I've got the support of the public," she said.

Dickson motivated by personal gain, LNP colleague says

LNP Leader Tim Nicholls said he was given 15 minutes notice of the resignation, and was disappointed Mr Dickson did not tell his electorate of his intentions.

He said it was a selfish choice and a move that could make Mr Dickson a powerful figure in Queensland's hung parliament.

"Make no mistake about it, this has nothing to do with medicinal cannabis," Mr Nicholls said.

Mr Nicholls said Parliament had passed laws in support of medicinal cannabis, but Labor had slowed the delivery of the laws.

"This has nothing to do with the LNP," he said.

"Steve was just looking for an excuse to put his own self interests ahead of those of the people of Buderim.

"What Steve did today is exactly why people are fed up with politics.

"One Nation is doing exactly what Queenslanders hate. It is playing the political game."

Acting Premier Jackie Trad said Mr Dickson's move reflected badly on Mr Nicholls.

"It is Tim Nicholls that has failed today and it is Tim Nicholls who has a harder job ahead of him," Ms Trad said.

Crossbencher and Katter's Australian Party (KAP) MP Robbie Katter said Mr Dickson's move away from the LNP would be good for democracy in Queensland.

"Things happen in Queensland when you've got an active crossbench and we've been happy to play a strong role in that in the KAP and happy to do that with Steve Dickson," he said.

Mr Katter said sitting on the crossbench was a position that could make a difference.

"If you're on the crossbenches it's good to have some influence and good to have some numbers but you want to do something positive with that."

Mr Dickson has previously been criticised by the Palaszczuk Government for appearing in a video with Senator Hanson.

He has also posted videos on Facebook supportive of One Nation's policies.
