A right-wing extremist embroiled in an anti-Islamic mock beheading has been refused a security guard's licence after taking his fight to the civil tribunal.

Christopher Shortis argued he was a changed man, but the Victorian Civil and Administrative Tribunal disagreed, ruling the 48-year-old should not be allowed to work in that field.

“I am satisfied it is not in the public interest for Mr Shortis to be granted a licence,” senior VCAT member Anna Dea wrote.

The Chief Commissioner of Police had previously refused to grant Mr Shortis a security licence in part after he was convicted over a 2015 stunt, where he and two other men from the United Patriots Front performed a mock beheading outside the Bendigo council offices, protesting against the building of a mosque in the regional city.
