Pauline Hanson and Greens Senator Sarah Hanson-Young have clashed on live television after the One Nation leader refused to condemn the far-right group that heckled Sam Dastyari last week.

Senator Hanson-Young asked why Senator Hanson refused to speak out against members of Patriot Blue for their verbal abuse towards the Labor senator at a Melbourne pub, labelling her as "irresponsible".

Senator Hanson hit back: "I just want to ask her [Hanson-Young], does she have to work at being a nasty piece of work or does this just come naturally?"

Senator Hanson later said she did not support the behaviour of the far-right group.

Dastyari says extremism sparked by 'rise of Trumps and Hansons' after attack
Senator Sam Dastyari has responded to being racially abused in a Melbourne pub by urging Australians to call out extremism which he says is sparked by the 'rise of Donald Trumps and Pauline Hansons of this world’.

"I made it quite clear last week that no one deserves this. It is unacceptable. I think if Sarah had a look at what I copped for years: I had people throwing urine, tomatoes, eggs. I never heard one member of parliament stand up and support me," she said.

"It was not acceptable 20 years ago... it was absolutely disgusting. This is it, Sam [Dastyari] gets a few nasty words.

"You have called me time and time again a racist. You're a nasty piece of work Sarah Hanson-Young."

Senator Hanson-Young repeated her claim that Senator Hanson should condemn the group.

"We shouldn't see politicians giving cover for racists..." Senator Hanson-Young said.

Last week, Senator Hanson accused Senator Dastyari of using the incident to create publicity for his recently-released book.

"He's played up this whole thing," she told reporters on the campaign trail in Queensland.

"I've got absolutely no time for him whatsoever - I think he's a smart arse."

Senator Dastyari was heckled by far-right activists last week, with the Patriot Blue group sharing footage of the incident on their Facebook page. Prime Minister Malcolm Turnbull and Opposition Leader Bill Shorten condemned their actions.
