The Beards will play at The Royal Oak Hotel as part of their largest national tour, run in the name of fairness.

Provided that you too own an impressive jaw brush, of course.

Band vocalist Johann Beardraven said he would not stop until their message was received.

"Bearded people have been oppressed by beardless people for decades now, we're only just starting to fight back," Beardraven said.

"We're not unreasonable people, all we're asking is to be extended rights not granted to bearded people."

Since 2005, the band has become world renowned for championing their message originally intended as a joke during a once-off parody gig in South Australia.

"A lot less judgment is happening now than when we started the band," Beardraven said.

"The band started as grass-roots activist movement against the oppression that bearded people face, we want a chance to get a bit of solidarity and provide a voice for the bearded man."

Although there is no hierarchy within the beard community, Beardraven said, anyone adopting a minimalist approach to facial hair should feel ashamed.

"We really don't like the moustache, they're a poor man's beard," he said.

"I think to wear a moustache in our presence is really to spit in the face for everything we've done for beards.

"We want all people to have beards - I still feel like bearded people are in the minority group.

"Fifty per cent of males don't have beards, that's a real pity and a blight on our society. All people should have beards - that's including women, children, journalists and politicians."

The band will play from 8pm, supported by Melbourne two-piece rock outfit The Stiffys.

"Most people have the presence of mind to wear a fake beard, or draw a beard on when they come to our shows without one," Beardraven said. "It helps them blend in a bit - we will be persecuting you if you have no beard at the show, that's fair, bearded people been persecuted for a very long time now.

"Having said that, we do encourage anyone without a beard to come to the show and be confident hearing us play songs about beards."
