One Nation won't be directing preferences to either Labor or the Liberals in the Longman by-election, Pauline Hanson says.
Preferences from the minor party will be key to winning the July 28 by-election in the Brisbane seat, which is being recontested by Labor's Susan Lamb, who was forced to resign over her dual citizenship.
Senator Hanson released a video in which she talked down suggestions her party would favour the Liberals' Trevor Ruthenberg, who was campaigning with Malcolm Turnbull in the seat on Friday.
"The political parties are putting out there that One Nation are directing our preferences to the Liberal party or we are directing our preferences to the Labor party - that's not true," she said, in a direct message to voters.
"You own your preferences, not the political parties."
Asked whether the LNP could win without One Nation preferences, the prime minister told reporters the by-election was about whether voters supported Labor's "anti-business, higher-taxing agenda" or the coalition's plan for a stronger economy.
At the 2016 federal election, One Nation preferences split 52-48 in favour of the LNP in 12 Queensland seats.
In Longman, where the One Nation how-to-vote card directed preferences to Labor, the preferences flowed 56.5-43.5 in Labor's favour.
Political analysts found One Nation's decision at the 2017 Queensland state election to direct preferences against the Liberal National Party swung at least four seats to Labor.
Eleven candidates have thrown their hats in the ring for the by-election.
The Liberal Democrats' Lloyd Russell drew top spot on the ballot paper, with One Nation's Matthew Stephen in fifth position, Ms Lamb in eighth spot and Mr Ruthenberg ninth.
