One Nation leader Pauline Hanson has accused Prime Minister Anthony Albanese and Treasurer Jim Chalmers of fuelling the threat of political violence, claiming their attacks on her party have “crossed a line”.

The extraordinary intervention comes as tensions between Labor and One Nation escalate following the party’s thumping victory in the Secret Harbour by-election in Western Australia, with Ms Hanson taking to X to accuse the nation’s two most senior economic leaders of using “poisonous political rhetoric”.

“The attacks from Chalmers and Albanese on One Nation have become increasingly desperate. Yesterday they crossed a line,” Ms Hanson wrote.

“No matter how worried Jim and Albanese are about losing their jobs, telling Australians that their democratically elected opponents are ‘dangerous’ and a ‘threat to our country’ invites people to treat them as a threat.

“Words have consequences. That is how political violence is incited.”

Ms Hanson accused Mr Albanese of hypocrisy over his previous calls to lower the temperature of political debate, claiming the Prime Minister and Treasurer were instead “pouring petrol all over it”.

“Australians are entitled to vote for One Nation without being told by the Treasurer and the Prime Minister that their democratic choice is a danger to the nation,” she said.

“The real danger to Jim and Albanese is that the people of Australia are coming for their government… at the ballot box.”

Ms Hanson has now escalated the attack, posting a photograph she said was taken in Bendigo just an hour after Mr Thistlethwaite defended Mr Albanese and Mr Chalmers’ criticism of One Nation.

The One Nation leader claimed the image showed a person standing alongside a video-game character depicted blowing itself up “like a suicide bomber”.

“The standard you walk past is the standard you accept,” Ms Hanson wrote on social media.

“Labor has a problem with language that invites political violence against their opposition.”

The latest salvo follows an increasingly bitter war of words after One Nation’s victory in Secret Harbour, which prompted the party to declare there were “no more safe Labor seats” in Australia.

Mr Albanese responded by accusing One Nation of being prepared to “say anything and do anything to win votes”, claiming the party would “bend any facts, peddle misinformation and disinformation, turn Australian against Australian”.

The political fight spilled onto Sunrise on Monday morning, where Labor frontbencher Tanya Plibersek was grilled over the Government’s handling of immigration as One Nation MP Barnaby Joyce declared Australians no longer believed Labor.

Ms Plibersek insisted Labor would examine the Secret Harbour result but argued the Government was delivering “real change”, pointing to lower migration, higher wages, tax cuts, cheaper medicines and housing measures.

But she was challenged over polling cited by Sunrise showing One Nation and Labor neck-and-neck overall, while One Nation held a commanding 39 per cent to 19 per cent advantage over Labor when voters were asked which party was best able to handle immigration.

“Whatever you’re saying, it doesn’t sound like it’s cutting through. Tanya, what’s the problem?” Ms Plibersek was asked.

The Social Services Minister argued One Nation itself lacked clarity over how far it would cut migration, while insisting Labor had already acted.

“We’ve brought immigration down. We’ve almost halved it,” she said.

Ms Plibersek conceded, however, that delivering policy was only part of the challenge facing the Government.

“Oh, I think we need to keep making sure that Australians know that we are the ones that are actually delivering real change in this country,” she said.

“And of course, you’ve got a big part of the job in making the changes. Another part of the job is making sure people understand the changes.”

Mr Joyce seized on the exchange, bluntly telling the minister Australians did not believe Labor.

“No, I don’t believe you, Tanya. That’s the problem. Everyone’s just completely dispensed with any of your rhetoric. So you’re unbelievable,” he said.

Earlier, Mr Joyce launched an extraordinary attack on the Prime Minister and Labor, repeatedly branding them liars while celebrating One Nation’s Secret Harbour victory.

“They lie. I’ve said this so many times. They lie, they are liars,” he said.

“There is nothing more ridiculous than a liar accusing someone of lying. It is perverse.”

Mr Joyce said the result showed the political landscape had shifted.

“Yes, the dynamics in Australian politics have changed and if people don’t realise that they are foolish, there is no safe Labor seat anymore.”

Ms Plibersek rejected the suggestion the result alone represented a federal verdict, noting it was a state by-election, but acknowledged Labor would study what it could learn from the result.

“I say there haven’t been safe seats for any party for a long time. We don’t take any seat for granted,” she said.

The increasingly heated interview eventually descended into both politicians repeatedly speaking over each other, prompting the Sunrise hosts to announce a new rule for their next appearance: “one person talk at a time”.
