Neo-Nazi leader Thomas Sewell has avoided time behind bars over a brutal attack on a Nine Network security guard.
The 29-year-old leader of the European Australia Movement was convicted and sentenced to an 18-month community corrections order with 150 hours community service on Thursday in Melbourne Magistrates Court, where he was previously found guilty of recklessly causing injury and affray.
Sewell, who represented himself in court, asserted the incident was not racially motivated, saying he would have acted the same way regardless of the guard's race or culture in circumstances where he believed his colleague was under attack.
Magistrate Stephen Ballek previously found Sewell was "itching for a fight" when he visited Nine's building in Melbourne with cameraman Jacob Hersant and demanded to speak to someone from A Current Affair on March 1, 2021.
Sewell claimed a segment on the program showed his group to be terrorists and said he was not contacted for comment.
After staff declined to meet, Mr Hersant began filming Sewell inside the foyer, prompting the security guard to put his hand on the lens and tell the pair to stop filming.
The duo agreed to go outside but the guard followed them when they started filming near the door.
After they moved further away, the guard began making a dance-type motion to the camera, prompting Mr Hersant to taunt him, saying: "Dance monkey, dance."
The guard touched Mr Hersant's shoulder in an attempt to push him backwards before Sewell leapt in and began attacking him, punching him in the head at least six times.
The guard fell back and hit his head on concrete.
Mr Ballek described the attack as "brutal in its force, speed and repetition".
The security guard did not see the punches coming, he said.
"Members of the public who witnessed this ugly event were understandably terrified," Mr Ballek said on Thursday.
"The offending is sickening to watch on video. It would have been worse to observe live."
Sewell apologised to one witness who said in a victim impact statement they had nightmares after the incident.
He told the court the victim's fears that his supporters would try to intimidate them were unfounded.
The magistrate took into account his work history, along with his fiancee being 36 weeks' pregnant - a factor Sewell emphasised would lead to "undue suffering" through his sentence.
He also asked the court to consider his employer, saying he worked full-time as a labourer and apprentice. He previously served as an army rifleman and worked with disadvantaged youth, he said.
Sewell is due to face a separate County Court trial in August and spent seven months on remand in solitary confinement because of that case.
Anti-Defamation Commission chairman Dvir Abramovich said Victorians would feel less safe knowing Sewell was not jailed for his offending.
"There would be many asking themselves whether a community order sends a powerful enough message," Dr Abramovich told AAP.
"The law must always convey, in a clear and loud voice, that physical violence and expressions of bigotry and hatred will not be tolerated in Victoria."
