Some, such as LNP MP-turned-One Nation state leader Steve Dickson, have switched parties while others have been disendorsed, dumped or simply chose to leave their previous party.

But what chances do these candidates who have changed political allegiances have at the polling booths on Saturday?

Frank Mols, a lecturer at the University of Queensland's School of Political Science and International Studies, said Mr Dickson would be an intriguing candidate to watch in particular.

"It's a bit too soon to say but I think Steve Dickson might be an interesting one, I suspect he'll do well," Dr Mols said.
