One Nation's Queensland leader Steve Dickson has admitted he is not confident of retaining his seat at Saturday's poll.
"I have never, ever gone into an election campaign confident, not once," Mr Dickson told AAP on Friday morning.
However, the party's national leader, Pauline Hanson is backing Mr Dickson to win.
"I'm not just saying this, I really believe Steve is going to win his seat," Ms Hanson said outside a polling booth in his Sunshine Coast seat of Buderim on Friday afternoon.
Mr Dickson has held the seat since 2009 but is widely tipped to lose on Saturday after defecting from the Liberal National Party to One Nation earlier this year.

Speaking in Buderim, Mr Dickson said the boundary changes to electorates had complicated voting.
"Boundaries have been moved in my seat, unfortunately," he said.
"I think what people have got to understand in Queensland is this election is probably the most unique election we've ever seen in Queensland's history."
The Courier-Mail's Galaxy poll on Friday morning showed a statewide fall in One Nation's primary support from 18 per cent to 12 per cent, but in regional areas it was 20 per cent.
Expectations were high for the party in the West Australian election earlier in the year, before support ebbed away at the polling booths.
"I don't know how many seats we're going to win, I haven't got a clue. But what I know is, we're competitive, we're in the race and I think this is a totally different campaign to Western Australia".
