Senator Jacqui Lambie has accused One Nation of endangering her and her family, after a candidate for the far-right party's Tasmanian campaign leaked her phone number in a Facebook post.
It comes just a day after the independent senator excoriated One Nation for their proposed bill against vaccine mandates.
Lambie said the breach by candidate Steve Mav was particularly egregious given the febrile political environment.
"I have received many nasty, abusive and threatening phone calls and messages," she told parliament.
"You have the (federal police) briefing politicians about our safety, you have gallows on the steps of Victoria's parliament and senators in this very chamber should not be facilitating any abuse.
"One Nation have crossed a line here that should never be crossed."
One Nation Senator Malcolm Roberts told the chamber that Mav posted the number after being sent it by a voter who got it from a Facebook post from Senator Lambie urging veterans in need of help to contact her.
Appearing via videolink, Senator Roberts accused Senator Lambie of playing the victim and misrepresenting the circumstances - which was met by her shaking her head in the chamber.
Senator Lambie asked Senate President Slade Brockman to investigate the leaking of her number and decide whether Senator Roberts should issue an apology, as well as look at the safety of senators more broadly.
The Senate is considering both matters.
