One Nation is seeking a forensic audit to prove the success of its $2 million fundraising drive as top Liberals reject teaming up with the resurgent conservative party.
After Prime Minister Anthony Albanese raised questions about whether the amount raised was legitimate, a spokesman for One Nation leader Pauline Hanson said the party would bring in analysts to confirm the "fire the liar" campaign's legitimacy.
An independent forensic audit being commissioned would show the fundraising effort was authentic, the spokesman said.
"Why would I call out the liar ... then go and do something like that myself? It would destroy me," Senator Hanson later said at a media event in Western Australia.
Mr Albanese questioned what evidence there was the party had actually raised the funds, and Labor operatives privately suggested One Nation's online donation counter might have been fraudulent.
