One Nation has suffered another setback in the latest Roy Morgan poll, with support falling for the second week in a row after Pauline Hanson’s high-profile National Press Club address in June.

The poll, conducted from June 29 to July 5 among 1,584 Australian electors, shows One Nation’s primary vote dropping 3.5 percentage points to 22.5 per cent.

That follows a 5.5-point fall the previous week, leaving the party down a total of nine points from its recent peak of 31.5 per cent.

Labor held steady at 28 per cent, retaining its position as the country’s largest party.

The Coalition remained unchanged at 21.5 per cent, with 19 per cent support for the Liberals and 2.5 per cent for the Nationals.

The Greens gained one point to 14 per cent, while Independents and other parties rose by 2.5 points to 14 per cent.

The downturn for One Nation comes after Hanson’s National Press Club speech, where she declared Australia cannot be multicultural and must exist as a ‘monocultural society’.

Roy Morgan analysis shows support for One Nation has fallen at least 10 percentage points in the past fortnight across capital cities and the three biggest states, New South Wales, Victoria and Queensland.

Roy Morgan estimates Labor would secure majority government if an election was held now, whether One Nation or the Coalition was the final challenger in key seats.

That represents a three-point gain for Labor and a three-point decline for One Nation compared to the previous survey.

Labor also continues to hold a commanding lead over the Coalition.

Based on respondents’ stated preferences, Labor leads 55-45 on a two-party preferred basis, up 1.5 points. Preference flows based on the 2025 federal election still put Labor ahead 54-46.

It follows two other polls showing One Nation falling.

Last week’s Newspoll found Labor’s primary vote up three points to 33 per cent, while One Nation dropped two points to 29 per cent. The Coalition slipped to a record low of 17 per cent, and the Greens gained two to reach 13 per cent.

Meanwhile, the Financial Review’s RedBridge Group/Accent Research poll showed Labor rising two points to 30 per cent, overtaking One Nation, which dipped two points to 29 per cent.

The Coalition fell to 18 per cent, and the Greens climbed two points to a term-best 14 per cent.

RedBridge’s two-party preferred also put Labor ahead 56-44 over One Nation and 54-46 over the Coalition on preferences.

Using previous election flows, Labor led the Coalition 55-45, up from 52-48.
