Pauline Hanson has promised to "drain the billabong" in Queensland, echoing US President Donald Trump's pledge to "drain the swamp".

Speaking to media on the Sunshine Coast on Tuesday, Ms Hanson announced member for Buderim Steve Dickson as the state leader of One Nation in Queensland.

"I'm going to hand Queensland over to you now, although I'm still the senator, never forget that, for Queensland," Ms Hanson told Mr Dickson, the two clasping hands in a handshake and smiling at one another, with the senator wagging an index finger at her new MP.

"It's up to you now to lead the candidates in policy on the floor of parliament and just prove to the people what we want to do, what we want to achieve."
