One Nation has overtaken Labor in a new national poll conducted after the Federal Budget announced changes to negative gearing and capital gains tax.

The Roy Morgan poll surveyed more than 2,300 voters via text between May 13 and 14.

The survey found that primary support for One Nation was at 32 per cent, ahead of Labor on 28.5 per cent and the Coalition on 16.5 per cent.

On a two-party preferred measure, support was closely split, with One Nation on 49 per cent compared to Labor. When they were put against the Coalition, One Nation led 51 per cent to 49 per cent.

The poll also found dissatisfaction with the federal leadership, with 59 per cent of Australians saying they disapproved of Prime Minister Anthony Albanese’s performance, while 57 per cent disapproved of Treasurer Jim Chalmers.

Disapproval of the Prime Minister was recorded across gender, age groups and most states, with Tasmania the only state showing a slight majority approval.

According to the survey, motivations among voters differed sharply between parties.

Labor supporters were most likely to cite policy alignment and social fairness as key reasons for their vote, with 42 per cent pointing to shared values and 39 per cent to policy direction.

One Nation voters, however, were primarily driven by concerns about immigration levels (58 per cent) and dissatisfaction with the major parties (52 per cent).

The report also found One Nation supporters were influenced by broader concerns including perceptions of economic and cultural decline, opposition to “woke” policies and climate initiatives, and a belief the party “puts Australians first”.

It also highlighted personal support for One Nation leader Pauline Hanson as an “authentic and honest political figure” among supporters.

The polling follows a politically sensitive budget that included reforms to housing investor tax settings, which the Coalition has vowed to reverse.

It also comes after One Nation secured a second lower house seat, with David Farley winning the seat of Farrer, previously held by former Liberal leader Sussan Ley.
