Jacqui Lambie has taken another swipe at Tony Abbott, declaring the prime minister needs "a bucket of cement" to toughen up if he can't cop her criticism.
The outspoken Palmer United Party senator hasn't shied away from airing her dislike of Mr Abbott, who she's called a "bare-faced, uncaring liar" and a man willing to put his career ahead of his family's safety.
The political rookie isn't fazed by the stir she's caused, and has offered Mr Abbott some free advice about how to handle critics.
"If you're not used to attacks by now then you probably shouldn't be in that position," she told the Nine Network on Friday.
"You've got one of two choices. You can run and hide or you can say to yourself `here's a bucket of cement - toughen up'."
She also rejected suggestions she'd crossed the line by dragging families into the political argy bargy, rehashing her belief that Mr Abbott put his daughters at risk during the election campaign.
The former military police officer said there was a fine line between enlisting your family's support and "parading" them for political gain.
"Let's face it, they are really three gorgeous looking girls," she said of Mr Abbott's daughters.
"I can only hope that they can stay safe but I guess we'll see what happens in the future."
Senior government minister Christopher Pyne said he hoped Senator Lambie reflected on the respect and mutual support that's expected of politicians when she entered the Senate on Monday.
"I think Jacqui Lambie and all of us in Canberra should treat each other with the respect that all colleagues deserve," he told the Nine Network.
But Senator Lambie claimed she hadn't been offered the same courtesy and would keep up the biff, posing a prickly reality for the government as it tries to court the key crossbencher.
"You know what, start extending the olive branch or I guess we're going to be playing this game with each other for some time yet," she warned.
