The Australian Motoring Enthusiast Party (AMEP) has terminated its Victorian state council over an unauthorised Facebook page and liaising with the media without authorisation.

The closure comes less than a week after the Australian Electoral Commission confirmed AMEP's Ricky Muir would represent Victoria in the Senate despite receiving just 0.5 per cent of the primary vote.

A notice sent to all AMEP members lists a series of breaches, including the unauthorised establishment of social media presence and unauthorised media liaison.

A Facebook page was allegedly set up by the Victorian branch without the consent or authorisation of AMEP's central executive.

The letter also states the illegal and unauthorised use of AMEP identification, confidential information, incorrect policy announcements, and the misuse of the party brand.

The party's central executive - which is based in Queensland - will now take on a caretaker role for the Victorian council until further notice.

In his letter to AMEP members, chairman Tony Standfield says a directive was issued to all federal state councils that all media contact must be cleared by the national media liaison officer, Keith Littler.

It is claimed a Victorian official organised an interview with Mr Muir for a journalist from the Australian Financial Review without clearing it with Mr Littler first.

According to the letter from Mr Standfield, Victoria's state council has shown a "blatant disregard" for the direction and instructions set by the party's central executive.

'Internal domestics' frequent in minor parties

ABC election analyst Antony Green says it is not unusual to see this type of action in minor political parties.

"Some of these small political parties do have a habit of engaging in some of the worst internal domestics and arguments over control of the party," he said.

"We saw this with One Nation in the past; [the Democratic Liberal Party] had this problem in the past. To some extent it's because people are trying to exercise control over an elected senator, but the senator is the person with all the power.

"It doesn't matter what these people do inside their little party - they can sue each other, they can do all sorts of things - Ricky Muir is the elected senator.

"And the matter of the party only comes into consideration if for some reason he is no longer a senator and a replacement must be made in his place, and then it must come from the same party."

The now former chairman of AMEP's Victoria branch, Scott McDonald, spoke to PM from behind the wheel of a truck about his disappointment in the decision.

"I was there at the start. I set it all up," he said.

"Everybody that I've had contact with is falling apart - they just do not understand and they are really angry this has happened.

"They can't understand why because nobody has fed them any inside information. It's just everything has just gone all quiet all of a sudden."

PM spoke to Mr Littler, who said the letter was sent to members and there was nothing more to be said at this time.

Mr Muir, who supports the move to terminate the council, according to the letter, could not be reached for comment.
