One poll does not make a trend.

That is the obvious warning for anyone rushing to declare Pauline Hanson’s extraordinary political surge over after One Nation suffered its first meaningful setback in months.

One Nation has fallen three points to 26 per cent in the latest Resolve Political Monitor, ending a four-month run of uninterrupted growth.

Hanson herself suffered an even sharper fall.

After briefly overtaking Anthony Albanese as Australia’s preferred prime minister, the One Nation leader dropped eight points from 33 per cent to 25 per cent.

Albanese recovered four points to 33 per cent.

Opposition Leader Angus Taylor rose five points from 16 per cent to 21 per cent.

Labor remained steady on 28 per cent of the primary vote. The Greens were unchanged on 12 per cent.

And then there is the number that deserves particular attention.

One Nation fell three points. The Coalition gained three points.

The Coalition is now on 23 per cent, narrowing the gap with Hanson’s party to just three percentage points.

That does not prove a permanent voter migration is under way.

It does not prove One Nation has peaked.

It certainly does not mean the Coalition has repaired the political damage that allowed Hanson to overtake it in the first place.

But it is the first consequential movement in months that suggests some voters may be prepared to move back from One Nation to the traditional centre-right.

For Taylor, that is potentially the most important political development in the poll.

For Hanson, it is a warning.

The real question is no longer whether One Nation can attract disillusioned voters. It has already proved that. The question is whether Hanson can hold them once her party comes under the sustained scrutiny normally reserved for a potential government.

That scrutiny has arrived.

Only a month ago, One Nation appeared to be rewriting the rules of Australian politics.

The party reached 29 per cent in Resolve polling, overtaking Labor and the Coalition on primary vote.

Hanson moved to 33 per cent as preferred prime minister, ahead of Albanese on 29 per cent and Taylor on 16 per cent.

For a party that won just 6.4 per cent of the House of Representatives primary vote at the 2025 federal election, the transformation was extraordinary.

One Nation’s rise had moved far beyond the normal territory of a protest party.

Political analysts began examining whether Hanson could realistically form government.

Traditional two-party-preferred models became increasingly difficult to interpret because One Nation could potentially reach the final count in a large number of electorates.

At the previous federal election, One Nation was in the final two-candidate contest in just 26 seats.

Analysts have warned that support in the high 20s could put the party into the final count in more than 100 electorates, creating preference contests for which there is little modern electoral precedent.

One Nation was also beginning to build the physical infrastructure of a larger party.

Its breakthrough at the South Australian election delivered a substantial parliamentary presence.

The party has begun scouting Adelaide for its first permanent state headquarters outside Queensland.

Branches are expanding and One Nation is preparing for future campaigns with resources and political attention it has rarely possessed before.

That broader picture has not disappeared because of one poll.

Hanson’s party remains on 26 per cent.

That is still ahead of the Coalition.

It is still only two points behind Labor.

And it remains dramatically above One Nation’s federal election result just over a year ago.

This is why Barnaby Joyce’s caution about overinterpreting the result has some merit.

The One Nation MP has described polls as indicators rather than definitive political outcomes.

He is right about that.

Polling moves.

Samples contain margins of error.

News cycles influence voter sentiment.

A three-point decline can be reversed in the next survey.

But politicians who dismiss inconvenient polls entirely usually make the same mistake as those who celebrate favourable polls as election results.

The value of polling is not simply the headline number.

It is the movement beneath it.

And the demographic movement in this Resolve poll is particularly interesting.

One Nation’s losses were driven disproportionately by women and voters from immigrant backgrounds.

The timing follows Hanson’s renewed campaign against multiculturalism and her call for Australia to pursue a “monoculture”.

Resolve asked voters directly about the concept.

Thirty-nine per cent opposed a monocultural Australia.

Thirty-three per cent supported it.

The remaining respondents were undecided.

Pollster Jim Reed argued that One Nation had begun to look increasingly outdated to some voters.

That observation goes to the central political challenge confronting Hanson.

The issues that built One Nation’s surge are not necessarily the same issues that will take the party from 29 per cent to government.

Economic pessimism has created fertile territory for One Nation.

Australians have endured intense cost-of-living pressure, expensive housing and periods of falling real wages.

Confidence in the major parties has weakened.

One Nation has successfully connected those economic anxieties with its longstanding arguments on immigration, energy and government spending.

Research and political analysis in recent months have highlighted how the party has capitalised on a combination of high inflation and weak economic growth.

Hanson’s message is simple.

Australians are struggling.

Governments are spending too much.

Immigration is placing pressure on housing and services.

Net zero and renewable energy policies are increasing costs.

And the political establishment is not listening.

Whether voters agree with every part of that argument is almost secondary to its political effectiveness.

One Nation has given dissatisfied Australians a clear explanation for why they feel worse off.

The Coalition, meanwhile, spent much of the period after its 2025 election defeat struggling to explain what it stood for.

That created the opening Hanson exploited.

But political growth changes the rules.

A party polling at 6 per cent can speak almost exclusively to its base.

A party polling near 30 per cent cannot.

Once voters begin considering a party as a potential government, every policy and every controversial statement receives greater attention.

That is now happening to One Nation.

Taylor has deliberately intensified his attacks.

In a major speech at the Sydney Institute, the Opposition Leader accused One Nation of offering economically incoherent policies that could impose enormous costs on taxpayers.

He argued four One Nation proposals alone could cost about $1 trillion over a decade.

Taylor warned that the consequences could include higher inflation, higher interest rates and pressure on essential government services.

His attack was the clearest indication yet that the Coalition no longer views One Nation as a secondary political irritant.

It sees Hanson as an existential threat.

The Liberal Party cannot realistically return to government if it remains on 20 or 23 per cent of the primary vote while One Nation holds the mid-to-high 20s.

Taylor therefore faces a difficult strategic calculation.

He must win back voters from Hanson.

But attacking One Nation too aggressively risks alienating precisely the voters he needs.

South Australian Liberal senator Alex Antic has publicly warned about that danger.

Antic argues conservative voters are tired of political infighting and that treating One Nation supporters with contempt is unlikely to persuade them to return to the Liberal Party.

Most Coalition MPs have supported Taylor’s tougher approach.

Former prime minister Tony Abbott has also backed the argument that One Nation’s policies deserve intense scrutiny.

The latest Resolve poll provides Taylor with his first evidence that the strategy may be producing movement.

Again, the numbers are striking.

One Nation: down three.

Coalition: up three.

Hanson as preferred prime minister: down eight.

Taylor: up five.

It is not a perfect transfer.

Polling cannot tell us that every voter who left One Nation moved directly to the Coalition.

Some movement may be statistical noise.

Different voters may have changed their intentions in different directions.

But politically, the pattern is difficult to ignore.

If it appears again in the next Resolve poll, the debate changes.

A second consecutive decline would raise serious questions about whether One Nation has reached a ceiling.

A simultaneous Coalition recovery would suggest Taylor is beginning to consolidate the traditional centre-right vote.

That would be a genuine trend.

But there is another possibility.

One Nation may simply be experiencing the normal volatility that comes with rapid political growth.

The party’s support climbed at extraordinary speed.

It rose from about 6 per cent at the federal election to the high 20s in national polling within little more than a year.

No political coalition of voters assembled that quickly is completely stable.

Some One Nation supporters are long-term Hanson loyalists.

Others are former Liberal and National voters angry with the Coalition.

Some previously supported Labor.

Others are politically disengaged voters who have been attracted by One Nation’s anti-establishment message.

Those groups do not necessarily agree with each other on every issue.

A former Labor voter concerned about immigration and housing may have very different views on workplace rights from a lifelong conservative.

A suburban mother angry about electricity bills may not share Hanson’s position on abortion.

A migrant voter frustrated by rapid population growth may support lower immigration without supporting the idea of a monocultural Australia.

This is the coalition Hanson must now hold together.

The latest Resolve figures suggest some parts of it may be more fragile than others.

Women are particularly important.

One Nation has made substantial efforts to broaden its appeal beyond the predominantly male protest vote historically associated with right-wing populist parties.

Hanson’s own political persona can help with that.

She is a familiar figure who has spent decades presenting herself as an ordinary Australian willing to say what professional politicians will not.

But recent controversy around parental leave and abortion risks creating a different impression among some female voters.

The same applies to immigrant communities.

One Nation can potentially attract migrant voters who believe immigration levels are too high.

There is no contradiction in an Australian of immigrant background supporting lower future migration.

But rhetoric about “monoculture” may push those same voters away if they believe the argument questions their place in Australian society.

That is the political distinction One Nation now has to navigate.

Reducing immigration can be presented as an economic policy.

Opposing multiculturalism is a broader cultural argument.

The first can attract voters across traditional political and demographic boundaries.

The second may narrow the party’s potential coalition.

Hanson has never built her career by carefully testing every sentence through a focus group.

Her direct style is central to One Nation’s appeal.

Joyce has defended that quality, arguing Hanson speaks plainly and that Australians understand the need for cultural “guardrails”.

Attempting to transform Hanson into a conventional political leader could destroy the authenticity that attracted millions of voters in the first place.

But there is a difference between authenticity and strategic discipline.

If One Nation genuinely wants to form government, it needs to understand which arguments expand its vote and which ones simply excite people who already support it.

The latest Resolve poll may offer the first serious clue.

One poll does not make a trend.

One Nation remains in an historically strong position.

Hanson remains more popular as preferred prime minister than Taylor.

The Coalition remains behind One Nation on primary vote.

Labor remains stuck below 30 per cent.

Australia’s political system is still in extraordinary territory, with analysts warning One Nation’s rise has made the next federal election difficult to model using traditional assumptions.

But trends have to begin somewhere.

The movement from One Nation to the Coalition is now the number to watch.

If Hanson rebounds next month, July’s result will look like a temporary interruption to an extraordinary rise.

If One Nation falls again while Taylor continues to recover, the story will be very different.

Peter van Onselen’s warning is the right one: do not mistake a single poll for a trend.

But if the next poll shows One Nation down and the Coalition up again, nobody in Hanson’s party will be able to dismiss the pattern as easily.
