Member for Buderim Steve Dickson has defected from the LNP to One Nation.
Mr Dickson reportedly resigned from the LNP with a "succinct" letter, and was announced as joining One Nation at a press conference in his electorate on Friday.
It means One Nation will now have a vote in Queensland's hung parliament, when sittings resume on February 14.
The LNP logo was removed from Mr Dickson's website this morning, with the press conference moved from Maroochydore to Buderim adding fuel to the speculation he was about to join One Nation.
Ms Hanson was not expected to take questions.
Mr Dickson raised eyebrows in October after inviting Ms Hanson to visit his conservative Sunshine Coast electorate.
At the time, Ms Hanson said the Buderim trip was her first invitation to visit a state MP in their electorate.
She also told media she would not stand a One Nation candidate against Mr Dickson.
But despite speculation Mr Dickson was preparing to jump ship from the LNP, he told Fairfax Media he had no plans.
"No, not whatsoever," he said.
"I started as a Liberal ... I'm a very loyal team member."
Ms Hanson has announced 36 candidates to contest the next Queensland election, expected in the second half of 2017.
But two have already been dropped - the former candidate for Currumbin Andy Semple and former candidate for Bundamba Shan Ju Lin - following social media posts.
