A white supremacist found guilty of performing a Nazi salute during a film about the Holocaust says his political beliefs make him unemployable.

Self-proclaimed neo-Nazi Nathan Bull was found guilty of performing a prohibited salute at Cinema Nova in Carlton, in Melbourne's inner-north, by Magistrate Stella Stuthridge on Monday. 

Bull was charged after he and others disrupted a screening of The Zone of Interest by making Nazi salutes and mocking Holocaust atrocities on March 9, 2024. 

The Zone of Interest follows the horrifying daily life of Auschwitz commandant Rudolf Höss and his family, who build an idyllic domestic life in a house directly adjacent to Auschwitz concentration camp.

Six witnesses testified, including cinema patrons and staff, in a two-day contested hearing in May.

Bull, representing himself in court on Monday, was asked by the magistrate whether he thought he should be sentenced with or without conviction.

The 24-year-old said his job prospects had already been badly affected because of his far-right political beliefs. 

Bull told the court he relied on Centrelink payments to support his family. His partner is due to have their second child in coming days.

"It is quite difficult to get a job, obviously, because of who I am," he told the court.

"They can just Google me and they don't want the issues that it comes with being pulled up by communists, saying they have a Nazi working for them or the police showing up."

Bull did not apologise for his actions during the court proceedings. 

Police prosecutor Jessica McCartney said she believed a conviction would be in order given the gravity of the offending. 

Ms Stuthridge ruled Bull's ongoing court cases and political views had a "dramatic impact on his employability", and decided to sentence him without a conviction. 

"I think a conviction could only add to those difficulties," Ms Stuthridge said.

He was sentenced to a six-month community corrections order including 125 hours of unpaid work.

Previously witness Daphne Mohajer va Pesaran told Melbourne Magistrates Court the film focused on a concentration camp manager's mundane life, set against the horror occurring nearby.

She said she noticed a rowdy group of five when they first entered the small cinema and witnessed them "laugh and snicker" during a scene that depicted human loss.

"It felt like they were excited to be there, they were egging each other on and announced to the cinema that we'd been lied to, that the Holocaust didn't happen," Ms Mohajer va Pesaran said.

She said the group, seated in the front row, stood up and announced to the audience that "Hitler was a great guy" and "he didn't do anything wrong". 

Another witness Richard Schultz said he saw two members of the group, made up of four men and one woman, perform a Nazi salute in the cinema.

Bull wore a black Helly Hansen polo shirt in court, a clothing brand far-right extremists have appropriated because the prominent "HH" logo is interpreted as an abbreviation for "Heil Hitler".
