More than 100 men dressed in black — who the premier has described as “Nazis” — marched through Melbourne’s CBD early on Saturday morning, carrying Australian flags and chanting.

Police responded to what they described as a “pop-up protest” about 12:40am.

In a video shared on TikTok, a man can be seen carrying a placard while the masked group walks through Bourke Street Mall.

On Saturday morning, Premier Jacinta Allan said: “Nazis don’t belong in this country and they know it. That’s why they hide behind masks in the dark.”

Police said they responded quickly and the protest group eventually dispersed just before 1:30am, after arriving at Flagstaff Gardens.

An altercation allegedly occurred during the protest, when a 26-year-old man confronted the group and was assaulted, police said.

The man, of no fixed address, was taken to hospital with non-life-threatening injuries.

Premier says anti-vilification laws on the way

Ms Allan thanked police for maintaining public order.

“It’s clear they need more powers, and we’re giving it to them,” she said.

“Our criminal anti-vilification laws come into effect next month. We will introduce powers for police to unmask cowards at protests after that.

“We’re not afraid of these goons — but we won’t tolerate them, either.”

Victoria Police said no arrests were made during the protest, with police maintaining a strong presence throughout.

“Victoria Police respects the right to protest; however, there is absolutely no place for antisemitic, racist or hate-based behaviour in our society and police will not tolerate such activity.”
