One Nation leader Pauline Hanson has promised an advertising blitz targeting Labor leaders after being “gobsmacked” by a community fundraising campaign.

Hanson said the blitz would launch with State of Origin on Wednesday.

One Nation will spend around $300,000 on ads on free-to-air TV before the game, during the match on streaming platforms and on mobile digital billboards outside the MCG.

The first ad was released on social media on Tuesday. It shows Australians grieving at Bondi and living on the street as Hanson declares “people are screaming out for change”.

The single I won’t back down plays under the two-minute video, with the caption “you alone will decide the next government”.

One Nation is riding high in the opinion polls, and claims to have raised more than $4 million in donations in just under a week.

“[I] never thought we’d get anywhere near that money. We thought [it] might be by the end of the year, half a million or something like that,” Hanson told Sydney radio 2GB on Tuesday.

She said the rest of the money would be used to campaign against Labor ministers and Prime Minister Anthony Albanese.

“I want to get rid of Tony Burke, Chris Bowen and Clare O’Neil, [Andrew] Giles, all these people that have been incompetent, hopeless, bloody ministers that have actually made the country the state it is now,” she said.

The most recent Resolve survey, released on Sunday, showed Hanson ahead of Albanese as preferred prime minister, 33 per cent to 29.

Hanson said she wasn’t complacent about the rise in support, but indicated she would work with the Coalition if it unseated Labor from government.

“I’ve offered supply and confidence to Angus Taylor to the Coalition government so that we can get rid of this toxic Labor government. That’s my main aim,” she said.

Asked if Opposition Leader Angus Taylor had been in touch, after he said he would be, Hanson said she’d had no contact.

“I haven’t spoken to Angus since 2019 when he [was] environmental minister,” she said.

Also no Tuesday, Assistant Minister to the Prime Minister Patrick Gorman said there had been a major shift in politics, with the traditional left versus right political contest replaced altogether.

Gorman said the shift was changing how politics was done and “moving the mountains of public debate as we know it”. He said the traditional divide in Australian politics had been supplanted by a split between populists and the practical.

“We each have a choice as to how we respond to these forces. Do we use them to build Australia up or do we use them to fight over the scraps left when politics lets people down?” Gorman said in a speech to the McKell Institute on Tuesday.

He said Labor was the “only practical party of the centre” in Australia, in contrast to the Coalition, Greens and One Nation, which he said had abandoned policy development in favour of populism.
