Pauline Hanson is confident One Nation will get a groundswell of support as Queenslanders vote in the state election.
"This is going to be the real beginning and resurgence of One Nation," she told AAP, while speaking outside a polling booth in the Sunshine Coast seat of Buderim.
"We're going to win quite a few seats here in Queensland and I think that's going to carry across to the next federal election too."
Senator Hanson refused to speculate on the number of seats but was confident the party would poll well.
"I'm not saying (how many), I've got a number in my head ... but I think there is strong support for One Nation," she added.
She pointed to the 1998 Queensland election when One Nation won 22 per cent of the primary vote and 11 seats in parliament.
"This is as strong, if not stronger," she said.
Voting continued on Saturday afternoon, but in an ugly incident a One Nation volunteer was allegedly spat on and sworn at while handing out how-to-vote cards in Brisbane's north.
James Ashby, Senator Hanson's chief of staff, told AAP the volunteer was spat on at a polling booth in Aspley on Saturday morning.
"It is absolutely vile and disgusting behaviour," he said.
Queensland Police confirmed they were aware of the incident, but said no official complaint has been made as of Saturday afternoon.
Queensland One Nation leader Steve Dickson, meanwhile, cast his vote in his Sunshine Coast seat of Buderim, which he is under pressure to hold, at a different polling booth.
Mr Dickson voted at Buderim Mountain State School, after admitting to AAP he was not confident of holding the seat.
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."
