Indigenous senator Lidia Thorpe has appeared to walk back on a previous pledge to leave federal politics at the end of her current parliamentary term, saying she will run again.

Senator Thorpe, who was elected to the Senate for a six year term on a Greens' ticket in 2022 before leaving the party in 2023 due to a difference in their support of the Voice referendum, previously said she would leave parliament when her term expires in 2028.

"I don't intend on running again, definitely not," she told Nine's 60 Minutes program in 2023.

"I'm 50 next month ... I don't want to become an old crusty politician with old daggy ideas, we need new people coming in with fresh ideas."

Speaking on the Serious Danger podcast, the Victorian Senator seemed to walk back on that commitment.

"I have a responsibility to maintain a Blak Sovereign voice in that Parliament to keep them accountable, to hold them all accountable, including the Greens," she said.

"I was a bit selfish saying, 'That's it, I'm going, I need a rest'."

Senators are elected to six-year parliamentary terms in Australia, with the Gunnai, Gunditjmara and Djab Wurrung woman saying she intended to campaign on a ticket with another Blak Sovereign Movement member, with the plan to eventually hand over the seat if elected.

"I will run again, just to see if I can get that seat back, and then I'll hand it over," she said.

"We've just got incredible talent amongst our younger generation, and they should be in that place [Parliament]."

She argued too often people were "too frightened" or were "towing party lines" in Parliament to achieve meaningful action, before adding: "We've got a long time, we've got to get there first."

These include her protest against King Charles last year, and claims by Labor's Penny Wong that she had engaged in "aggression" and "hateful personal attacks" in the Senate, the latter of which saw her suspended for the final parliamentary sitting day of 2024.

On the podcast, Senator Thorpe responded to comments by Peter Dutton, who claimed she didn't deserve to be in the Senate.

After Senator Thorpe said the opposition leader was a "violent person" who, as a former Queensland police officer, "caused damage to a lot of blackfellas on the street," Mr Dutton, who has been criticised for not holding press conferences in Canberra and instead routinely going on 'friendly' media channels, told Ben Fordham on 2GB: "Obviously just absurd statements. She's a publicity seeker…I don't think she deserves promotion. She shouldn't be in the Senate."

"She's not stable enough to be a member of the Australian parliament and I think people recognise that through her actions," he added.

In response, Senator Thorpe noted: "Who's Peter Dutton?"

"I don't care what he says about me. It doesn't sway me one way or another. And for him to say that I shouldn't be there—that's not his decision…it means nothing to me," she said.
