One Nation's public fundraising campaign is a "smokescreen" for the money coming in from billionaire donors, a Labor powerbroker says.
The Pauline Hanson-led party is claiming to have raised more than $3 million from almost 50,000 donors to its anti-Labor "fire the liar" campaign.
Prime Minister Anthony Albanese and other Labor figures have cast doubt on the legitimacy of the fundraising drive, prompting Senator Hanson to share an "independent audit" document authored by a software engineer to her social media page.
Former federal treasurer Wayne Swan labelled One Nation the "billionaire's party", highlighting its links to Australia's richest person Gina Rinehart who in April gifted Senator Hanson a $1 million plane.
"When it comes to big money in this country, it's all going to One Nation," Labor's national president told Nine's Today on Friday.
