A new poll has found surging support for One Nation after Pauline Hanson’s fiery speech last week railing against multiculturalism and immigration.

The Roy Morgan survey said if a federal election were held now, the winner would be “too close to call” between Labor and Hanson’s party.

“On a two-party preferred basis, the result could be: ALP 51 per cent cf. One Nation 49 per cent,” said Roy Morgan’s release.

The battle in many electorates across the country would be between the ALP and One Nation.

Following Hanson’s National Press Club address, the poll found primary support for One Nation had risen two per cent to 31.5 per cent.

This put the right-wing party “clearly ahead” of the ALP which was down one per cent to 27 per cent, stated Roy Morgan’s analysis.

The Coalition was up 0.5 per cent, rising to 17.5 per cent, putting the Liberals and Nationals out of contention to lead the country.

Support for the Greens was down 0.5 per cent to 13.5 per cent, and Independents/ Other Parties were down 1 per cent at 10.5 per cent.

The survey of 1575 Australians was conducted from June 15 to 21.

One Nation says its ‘Fire the Liar online campaign targeting Prime Minister Anthony Albanese has now raised more than $4.7 million from 75,000 donors.

The fundraising drive was in response to Labor’s call for members to donate $27 for a social media campaign targeting One Nation.

Labor is trying to position the right-wing party as one of grievance rather than a legitimate alternative government that offers solutions.

A separate poll released on Monday showed One Nation could win between 54 and 63 seats if an election were held now.

Labor would retain government but could be in minority with between 65 and 74 seats, the DemosAU survey published by Capital Brief shows.

The Coalition would hold between four and 11 seats, while the Greens and independents would each have fewer than 10.

These are the latest in a series of polls showing mounting support for One Nation.

Hanson’s party is now the most popular in Australia, leading both Labor and the Coalition on primary votes, according to multiple opinion polls.
