One Nation Senator Pauline Hanson is calling for the Labor candidate for Hervey Bay to be disendorsed over allegations he "physically" assaulted his One Nation opponent.

During Senator Hanson's trip to the electorate, cameras captured a run-in between her and the ALP candidate Adrian Tantari.

Senator Hanson claimed Mr Tantari gave her the finger as she was driving away from the polling booths.

"I was driving off and he actually gives me the finger, and that was not good enough, so I actually stopped the car in the middle of the road," she said.

"I went over and I confronted him and told him I will not put up with bullying and it's not good enough.

"We don't need people like him on the floor of Parliament and now I'm actually calling on [Premier Annastacia] Palaszczuk to get rid of him — disendorse him."

Senator Hanson said her candidate for Hervey Bay, Damien Huxham, had been targeted by Mr Tantari before.

"He [Mr Tantari] has actually bullied Damien at the polling booth — physically — and he's nothing but aggressive and he's a nasty piece of work," Senator Hanson said.

"He's a bully and we don't need that."

Mr Huxham said Mr Tantari had used profanities about him on social media and had uploaded a video attacking Mr Huxham for not being in town for one week of the election campaign.

"He actually came up to me and tried to grab me twice, and threatened me, which I actually reported to police," Mr Huxham said.

Mr Tantari has denied any conflict between himself and the One Nation candidate.

"One Nation has attempted to get right down into the gutter in this campaign to besmirch me, and use what I think are very dirty tactics against me," Mr Tantari said.

He also denied giving Senator Hanson the finger and labelled their accusations as dirty politics.

"That's just a total fabrication — I was just standing there talking to a campaign worker and suddenly I was confronted by Pauline," Mr Tantari said.

"She was very aggressive … in my face … she had a go at me for something she said may have occurred and I just asked her to explain herself."

Mr Tantari said it was all just a stunt to elevate Mr Huxham's profile in the electorate.

Queensland police are yet to confirm whether a formal complaint has been made about the candidate.
