Mr Burston has dug in after Ms Hanson’s tearful tirade against him last week, telling the Newcastle Herald he was “not stressed, even in the slightest bit” after days of turmoil.

But any moves by Ms Hanson against him would spell the end of the party, he said.  

“If she gives me the flick or forces me out, that will be the end of One Nation. People will see it as the party imploding for a second time. For her most loyal supporter to be pushed out because of one dispute, people will see the party as a dictatorship and Australians won’t like that,” Mr Burston said.

“It’s very very sad. I want to sit down and talk. She wants me to walk and I’m not walking.”

Mr Burston wrote to Ms Hanson on Monday warning it was a possible “contempt of the Senate” for her to pressure him into changing his vote on the company tax bill. His refusal to follow a One Nation backflip on the government’s bill was the catalyst for an extraordinary television outburst by Ms Hanson against Mr Burston, who regarded himself as one of her most loyal supporters.

In an interview with the Herald Mr Burston said he had been attempting to have a meeting with Ms Hanson since the outburst but “she just wants to bag the shit out of me in the public arena”.

He said a cooling of their relationship started in March during an attempt to hold a meeting that ended with Ms Hanson refusing to attend without staffer James Ashby.

Ms Hanson appointed Mr Georgiou party whip after stripping Mr Burston of the position last week, but Mr Burston said there were already signs Mr Georgiou might be next out of the leader’s favour.

He said Ms Hanson had failed to endorse Mr Georgiou and himself as number one on One Nation’s Senate spots for NSW and Western Australia.

“Peter will fall too. It’s not far away. She won’t endorse Peter and I. I’ve asked, ‘Are Peter and I going to be endorsed as number one?’. No response,” Mr Burston said.

Mr Georgiou did not respond to a request for comment.

Mr Burston repeated that he was not going to stand down from the Senate or the party and would be in Federal Parliament for the next two-week sitting from June 18 in his seat behind Ms Hanson.

He predicted Ms Hanson would “try and pressure me out by continuing to publicly humiliate me”.

In his letter to Ms Hanson he warned she could be sanctioned in federal parliament for breaching Senate rules by trying to punish him for refusing to vote the way she wants. 

He criticised Ms Hanson for a “pattern of behaviour” which has left him twice on the outer, as one of a list of former supporters eventually rejected from the party.

“She’s been to my engagement party and wedding and I’ve been to Port Stephens and stayed with her. We were almost family. But once you cross Pauline Hanson, the fiery readhead, you’re gone.”
