In some parts of Australia, voters are turning from the Coalition and falling into the arms of Pauline Hanson’s One Nation party. Here is how the party could win extra Senate seats this election.

One Nation is increasingly confident that a surge in support for Pauline Hanson will see it win extra seats in the Senate at the expense of the Coalition – a view backed by polling experts.

At this election, each state has six Senate spots up for grabs, with parties on the right likely to claim three in each race.

A significant lift in backing for One Nation, combined with a drop in support for the Coalition, has Ms Hanson’s party in contention for the third conservative Upper House seat in all contests.

One Nation finished seventh in all states in 2022, apart from in Queensland, where Ms Hanson came fifth and was elected.

According to polling analyst Kevin Bonham, since then, One Nation’s support has risen from about five to eight per cent.

One Nation is particularly hopeful about South Australia, according to its other elected representative, Senator Malcolm Roberts.

The party is also in contention in WA, Victoria and Tasmania, Mr Roberts said.

“One Nation is now starting to really attract younger voters, especially young families,” he told this masthead. “And something that’s quite remarkable – professionals are coming to us.”

The policies that are “resonating” include “deporting 75,000 illegals”, slashing immigration and banning foreign ownership of real estate.

Mr Bonham said that potentially, One Nation “are winning senate seats in a lot of places.”

Another psephologist William Bowe said: “If the Liberals’ vote is in the low to mid 30s then they are not getting three seats and that quite often means there’s another seat (available) on the right and One Nation seems to be the party.”

Mr Bonham said: “South Australia and Western Australia are easier than NSW and Victoria but they could potentially win all of those.”

In SA, One Nation’s top senate candidate is Jennifer Game, whose daughter Sarah has represented the party in state parliament since 2022.

In WA, the lead One Nation candidate is construction businessman Tyron Whitten.

Mr Bonham said in Tasmania, “there is a little bit of talk (One Nation’s) Hanson might squeeze out Jacqui Lambie,” who is facing re-election.

Lee Hanson is Pauline Hanson’s daughter.

Mr Bowe said he didn’t believe Lee Hanson would win.

But Mr Bonham, who lives in Tasmania, said the local Lambie campaign had lacked energy.

One Nation’s Mr Roberts said: “Lee Hanson is a phenomenal human being. She would make a very, very good senator.

“And Jacqui Lambie seems to be spending a lot of time and interest on other states.”

While Pauline Hanson is not up for re-election this time, Mr Roberts is, in Queensland.

He will win, the psephologists said, but One Nation wouldn’t get an additional seat in the Sunshine State.

A third polling expert, Malcolm Mackerras, said he expected the Coalition to fend off the One Nation challenge.
