Senator Hanson on Thursday claimed a decision by the Liberals to preference Jacqui Lambie Network candidates ahead of One Nation candidates in Tasmania was the result of a deal struck between the parties.

"Liberal voters will be despairing as their party lurches to the left on issue after issue in a betrayal of their Australian values," she said.

Senator Hanson said as a result, One Nation would preference the Liberals after Labor in Tasmania, Queensland and Western Australia.

Senator Lambie said no deal had been done.

"Tasmanian voters decide their own preferences," she said.

"Queenslanders like One Nation don't get to decide for anybody here.

"For all her talk about sticking up for freedom, Pauline's spat the dummy because she wants to control what the Liberal Party puts on its how-to-vote cards."

Senator Lambie also rejected One Nation's claim that her party was 'green-left'.

"I vote with the government 50 per cent of the time," she said.

"The Greens vote with the government 5 per cent of the time.

"I don't know what makes me green-left other than not agreeing with Pauline all the time."

There looks to be a three-horse race for the sixth senate seat in Tasmania this election between Liberal senator Eric Abetz, Jacqui Lambie Network candidate Tammy Tyrell and One Nation candidate Steve Mav.

A survey by the Australian Electoral Commission following the 2019 election showed 25 per cent of voters were assisted by how-to-vote cards in filling out their Senate ballot paper.
