The office of Ricky Muir has imploded after the novice senator sacked his chief of staff, Glenn Druery.
Mr Druery was escorted out of the Parliament by officers on Thursday night.
Senator Muir, who represents the Australian Motoring Enthusiast Party, sacked the man known as ''the preference whisperer'' in an email on Thursday.
Fairfax Media understands that a personality clash had emerged between Mr Druery and Motoring Enthusiast party founder Keith Littler.
Mr Littler, a truck driver from Queensland who produces motor sport videos, has moved to Melbourne with his wife Sharyn, to steer his electorate office.
Mr Littler ran for the Senate in Queensland, where the party was formed, but it was in Victoria that the party found success - through a preference strategy designed by Mr Druery.
Senator Muir and Mr Littler have been attending motorsport events outside of parliamentary sitting sessions.
In an email to Mr Druery on Thursday night, Senator Muir said: ''You don't get along with the staff.''
Another member of staff, Susan Bloodworth, who works in the Melbourne office, has quit in protest.
Canberra-based policy adviser to Senator Muir, Peter Breen, declined to comment on Friday, but he is understood to be considering his options.
The upheaval comes as Senator Muir lost the support of the Victorian branch of the party, which voted to disband itself this week.
Mr Druery told Fairfax Media: ''I don't expect the party to survive in the long term but I wish Ricky all the best.''
Mr Druery said he was not willing to move to Melbourne and has found it hard to perform his task from Sydney where he has four children.
