Prime Minister Anthony Albanese has condemned the actions of a group of men who wore black balaclavas and brandished Australian flags while swarming a Sydney train.
The group of about 60 hooded men, mostly wearing black masks and clothes, were seen at Artarmon station about 11.30am on Friday.
After boarding a train heading towards the CBD, the group was stopped at North Sydney station by more than 20 police officers.
"Officers boarded and contained the group of approximately 61 to a few carriages," NSW Police said in a statement on Friday.
Passengers not involved with the group were evacuated. Police said the group concealed their faces and were carrying shields and a flag.
Six people were arrested and taken to Chatswood Police Station and a further 55 men were fined for offensive behaviour.
Speaking to reporters on Saturday, Albanese said he was "horrified" by the images, but noted the head of Australia's domestic spy agency had repeatedly warned of the rise of neo-Nazis and right-wing extremism.

"It has no place and it has rightly been condemned by all decent people," he said.
On Saturday, NSW Premier Chris Minns called the behaviour "obnoxious" and "racist", telling fascists "you are not welcome here".
"This sort of ridiculous behaviour is so out of keeping with the kind of culture that we have built up in this state," Minns said.
"If people are attempting to reconvene and do this again, they're going to be met with overwhelming force from the NSW Police."

The 30-year-old self-appointed leader of the National Socialist Network was filmed being served by officers with a legal order banning him from attending any Australia Day events in Sydney.
The video, first posted by Sewell on his encrypted chat on Friday afternoon, was widely circulating across social media.
"You're being served with a public safety order," an officer tells Sewell in the video.
"I believe your presence in the Sydney City local government area poses a serious risk to public safety," the officer adds.
"This is based on your ideological links, including your associates, your previous attendance and ideologically motivated public order incidents, your criminal history of assaulting members of the public and your goal of intimidating and provoking people."
Sewell is then told to remain out of the Sydney City local government area or anywhere where an Australia Day event is planned until 11.59pm on Friday.
"So we're not allowed to celebrate Australia Day?" Sewell asks the officer.
On Friday, Minns said "normal people don't celebrate Australia Day with a balaclava on" in a statement.
"Due to great police work millions of Aussies were able to celebrate and come together without a potentially ugly confrontation.
"There is absolutely no tolerance for this behaviour," Minns said.

He was among a group of far-right National Socialist Network and European Australian Movement members who set upon a group of friends hiking in the Cathedral Ranges State Park.
On Friday morning, Sewell posted a photo of a recently vandalised statue of Captain Cook in Melbourne to X, formerly known as Twitter.
"A day before our National Day, anti-White scum cowardly tore down a Statue of one of the greatest sons of the Anglo Saxon Race - Captain Cook," he wrote.
"We will respond, and the world will know, that there are White men in this land who are still worthy of being called - Australian."
