Pauline Hanson has vowed to repeal hate speech laws if she secures the numbers in Parliament, telling supporters, "we have to bring our freedom of speech back" at a rally in Canberra.
The One Nation leader addressed a crowd on the lawns of Parliament House on Sunday as part of an event organised by March for Australia.
"If we get the numbers, we will repeal those hate speech laws. We have a lot of work to do, but you, the people, must make sure you make your vote count at the ballot box and don't keep returning these idiots," she said.
The laws were introduced earlier this year following the Bondi terror attack, and are designed to crack down on hate speech and extremist behaviour, including making it an offence to incite hatred or support banned hate groups.
Hanson has previously argued against the laws, warning they threaten free speech and arguing they were rushed through Parliament.
"You have a right to have a voice, you have the right to have an opinion, and make sure that you use that; otherwise, these governments around the country will suppress you as much as they can."
The rally was promoted as a show of support for Australia Day and national identity, with organisers calling on attendees to "stand together" and defend the country's traditions.
Hanson also used her speech to argue Australia should prioritise domestic issues over international conflicts.
"My job as a member of parliament is not for Palestine, not for Gaza, not for Israel, not for Britain," she said.
"Clean up our own backyard first and foremost."
Hanson pointed to what she described as growing support for her party, which has recorded a recent polling surge and strong results at the South Australian election, where it outpolled the Liberals on primary vote and won multiple lower house seats, following the defection of Barnaby Joyce to One Nation.
"Barnaby is absolutely loving being with One Nation... he can say what he wants to say. I don't control my members of parliament because we all are on the same page working for you without fear or favour," she said.
Despite the recent changes in her party, she said her long-standing political message remained unchanged.
"We are Australians," she said.
"The number of people that have come up to me today and have said thank you. It's very touching because when I got into this 30 years ago.... I stood my ground on one issue, equality for all Australians," she said.
"That wasn't good enough for the liberal party or for John Howard; that's when they threw me out of the liberal party. But the people of Australia understood what I was saying because I went on to win that seat".
"Today, that is still my message, equality for all Australians".
Independent MP Bob Katter also addressed the rally, saying he was working closely with Hanson and her party.
"We vote together and very much in the interest of Australia," he said.
"We're not interested in pleasing some little piss-ant party people in Sydney. We'll be looking after the people that sent us to Canberra".
At times during the speech, some attendees could be heard heckling, while others in the crowd moved to shut it down.
Similar rallies are being held across the country on Sunday, including in Hobart, Melbourne, the Gold Coast, Adelaide, and Perth, with another planned in Sydney on Monday.
