One Nation leader Pauline Hanson says she is preparing to roll out a multimillion-dollar campaign targeting the Albanese government, with television ads slated for Wednesday night's State of Origin clash.

The push will be backed by One Nation's 'Fire the Liar' fundraising drive, which is on track to exceed $4million.

The campaign centres on Prime Minister Anthony Albanese and what the party describes as Labor's backflip on negative gearing and capital gains tax, after pledging not to make changes before shifting position in the latest federal budget.

The fundraising effort has surged well beyond its original target. 

Launched earlier this week with a $1million goal, it had reached $3,832,967 as of Sunday afternoon, prompting organisers to lift the target to $4million. One Nation says 62,523 donors have contributed so far.

Hanson has promoted the campaign's reach online, sharing a national heat map of contributions to highlight widespread support.

'This is real money, real data, and a real campaign to get rid of Labor,' Hanson said on Sunday.

'It proves you're not alone in your support of ousting Australia's worst Prime Minister.'

She also issued a direct warning to the Prime Minister, declaring: 'Albo, you underestimated the anger of the Australian people and as a result, we're coming after you.'

Labor figures have pushed back strongly against the campaign, with former treasurer and Labor Party federal president Wayne Swan dismissing the effort as a 'smokescreen'.

He pointed to Hanson's association with mining magnate Gina Rinehart, who previously gifted her a Cirrus G7 private aircraft worth more than $1.5million.

'This whole debate is a smokescreen for the fact that they are actually run by the top end of town, and they deliver the policies for the top end … and wage suppression for the rest,' Swan said.

Hanson has continued campaigning on the ground, including hosting a fundraiser in Melbourne on Friday that was moved to a different venue amid concerns about protests.

The event, featuring Hanson and Nationals MP Barnaby Joyce, was initially scheduled for Giorgio's Restaurant in Moonee Ponds. 

A party spokesperson said organisers relocated the function following advice from Victoria Police and the Australian Federal Police after protest groups flagged plans to demonstrate outside.

Hanson, however, rejected that account, insisting the decision reflected overwhelming demand.

'Do you think I'd be deterred by the protesters? Think twice. No. We just had so many people who wanted to come,' she said.

The campaign push comes as One Nation claims growing momentum in opinion polling. 

A Newspoll released last week placed the party on 31 per cent of the primary vote, up four points since the previous survey conducted after the May 12 budget.

Labor recorded 30 per cent, down one point, while the Coalition fell two points to 18 per cent. 

The Greens stood at 11 per cent, with support for other parties unchanged at 10 per cent.

Hanson has signalled that One Nation will use that momentum to aggressively target Labor-held seats at the next federal election, with a particular focus on Western Sydney electorates held by senior ministers including Tony Burke and Chris Bowen.
