Members of Australia's far-right nationalist movement have opened a new exclusive men-only club in two eastern states, with plans to expand throughout the country.

Blair Cottrell, leader of far-right group United Patriots Front, said he had been working with others to establish the Lads (sic) Society "social clubs" for the past six months.

"Basically my colleagues and myself, we've set up a social club — we're building a community, a physical network of people," he said on social media.

"No longer are we just going to sit on Facebook and complain about what's going on, we're actually going to rebuild an Australian community for ourselves.

"We're doing it in Melbourne and Sydney."

Amateur promotional videos of the Lads Society show men standing around in groups while others box each other, in scenes seemingly paying homage to cult classic film Fight Club.

The group also claims to hold weekly members-only "fight nights".

While the private club has not published its address and requires direct contact to join, it is understood Melbourne's club is located in the south-eastern suburbs, 18 kilometres from the CBD.

The Melbourne club opened late last year and the Sydney club opened in April, with plans afoot to expand into other states.

The clubs include a boxing gym and a library, and hold seminars on subjects such as employment in the security industry.

"Values once venerated such as courage, strength, nobility, resourcefulness and loyalty are being sapped from our young men before they come of age…," the club said on social media.

"This leads to a future devoid of the calibre of man required to raise our society back up to the heights it should rightly achieve."

Mr Cottrell is currently appealing a Victorian conviction and $2000 fine for knowingly engaging in conduct with the intention of inciting serious contempt for or revulsion of a class of people.

He and two supporters were charged in 2015 after making a video protesting the construction of a mosque in Bendigo, in which they beheaded a dummy with a toy sword and spilled fake blood on the footpath outside Bendigo City Council offices.

"They'll try to shut us down"

In a statement to the ABC, Mr Cottrell said he expected the Victorian Government would move to shut down the club.

"In Queensland freedom of assembly was done away with and the police have been given despotic powers over motorcycle clubs or anyone even suspected of being involved with a club," he said.

"We're a registered business and all above board, but based on the level of surveillance, censorship and legal action I've experienced for simply for sharing my opinions, I believe the government may move in the future to try to prevent ordinary citizens with specific views and attitudes from getting together at all."

Exclusive ideology-driven clubs "a concern"

Griffith University criminology expert Professor Geoff Dean said the formalisation of the group into a bricks and mortar social club was a concerning development.

"They concern me these sorts of groups that get cloistered away — it almost becomes cultish," Professor Dean said.

"The thing with an online social media presence is that you don't have the same level of influence over someone if they are personally a member, and go to a gym, go regularly to meetings, sit within a physical space and relate to others.

"That can actually intensify the radicalisation or the extremism because they're having that much direct contact."

An ideology driven group created an "echo chamber effect" that only reinforced views, he said.

"Any group that does that, left-wing or right-wing, I have concerns about," he said.

Evidence precious freedom of assembly still remains

However University of South Australia adjunct professor of law Rick Sarre cautioned against any future attempt by authorities to intervene in the men-only club.

"Their ability to assemble in that way is one of the precious freedoms we have," Professor Sarre said.

"The left can get together, unions can get together, so why can't the right?"

He said laws introduced in some states gave the police powers to intervene in clubs including outlaw motorcycle groups, but only when there was strong evidence that something illegal was happening.

"In order to control the sorts of activities that come from group think, the trick is not to piss them off," Professor Sarre said.

"You want to make sure an eye is kept on them but you need to play the game fairly.

"If they want to get together to have a gym and talk about right wing things, good luck to them."
