A war of words has erupted between Prime Minister Anthony Albanese and One Nation leader Pauline Hanson after the Prime Minister publicly questioned the legitimacy of the minor party's recent fundraising success.

The dispute centres on One Nation's anti-Labor campaign, titled "Fire the Liar", which the party claims generated more than $2 million in donations within just over 24 hours. The campaign was launched in response to Labor's own fundraising efforts targeting the growing popularity of One Nation.

Speaking to reporters in Sydney, Mr Albanese cast doubt on the fundraising figures.

"Did she though? Did she? What evidence is there?" the Prime Minister asked.

He described the campaign as an example of politics driven by slogans rather than practical solutions, saying his government remained focused on policies designed to improve Australians' lives.

Hanson responded sharply during a visit to Perth, accusing the Prime Minister of being unable to accept the level of support One Nation had attracted.

The Queensland senator insisted the donations were genuine and revealed the party had arranged for an independent audit to verify the figures.

"It's all receipted, it's all on a spreadsheet," Hanson said.

"Why would I call out the liar... and go and do something like that myself? It would destroy me."

According to One Nation, the campaign attracted contributions from approximately 28,000 donors, with the average donation reported to be around $59. Hanson suggested the Prime Minister's scepticism stemmed from Labor's comparatively modest fundraising performance.

"He can't even believe it himself," Hanson said.

"I heard on the grapevine he's only received about $20,000 for the Labor Party, so he can't imagine One Nation getting the support that we have."

The fundraising campaign has intensified concerns within both major parties about One Nation's growing electoral appeal.

Recent opinion polling has indicated increasing support for the party, particularly among voters dissatisfied with traditional political options. Labor strategists have reportedly begun developing messaging aimed at countering One Nation's rise ahead of the next federal election.

The controversy has also drawn scrutiny over the transparency of political fundraising.

While One Nation has pledged to release audited information confirming the donations, critics argue that questions remain about the identity of contributors and the mechanisms used to collect the funds.

Treasurer Jim Chalmers used a speech to Labor supporters to criticise One Nation, arguing that the party represented division rather than practical solutions.

Meanwhile, Liberal leader Angus Taylor declined to become involved in the dispute, stating that questions regarding fundraising practices should be directed to the parties concerned.

The escalating exchange reflects an increasingly tense political environment as Australia's major parties grapple with the growing influence of minor parties and independent movements.

For Hanson, the fundraising campaign has become a symbol of grassroots support and political momentum.

For Albanese, the issue highlights broader concerns about transparency and accountability in modern political campaigning.

Whether the independent audit fully settles the debate remains to be seen, but the clash has already ensured that One Nation's fundraising drive remains firmly in the national spotlight.
