Thomas Sewell, 32, raised his right hand to photographers as he was brought into Melbourne's Supreme Court from a prison van on Wednesday morning.
The leader of white nationalist group National Socialist Network sat in the dock, with his partner and eight others attending court to support him.
Sewell hired top barrister Dermot Dann KC to fight for his release a second time after his first bail attempt was rejected by a magistrate in September.
He has been charged with dozens of offences related to the August 31 Camp Sovereignty attack, including violent disorder, affray, discharging a missile and assault by kicking.
Prosecutors told the court Sewell said "let's get 'em" as he led a group of about 30 men towards the camp, at Melbourne's Kings Domain, which sits on a sacred site for Aboriginal and Torres Strait Islanders.
At least seven people were assaulted, including one camp occupant who was held down and kicked, another who was struck with a pole, kicked and punched, prosecutor Erik Dober told the court.
He said one victim was allegedly thrown to the ground and kicked in the head, requiring seven staples to their head, and claimed another was hit in the head with a flag pole.
Mr Dann said it was unfair for Sewell to remain locked up when 15 co-accused had been released on bail.
He said a trial over the incident might not happen for two years, and the maximum 10-year term for violent disorder was not "in the realm" of any sentence Sewell would be handed for his alleged role in the offending.
"If this man is not released on bail, will he spend more time in custody on remand than he would if convicted and sentenced?"
He also pointed to issues in the prosecution case after Sewell was charged with assault against "unknown victims", who the court heard were yet to be found.
Mr Dann said any risk Sewell posed to the community could be ameliorated by bail conditions, including stopping him from coming into Melbourne's centre and not contacting co-accused.
Sewell's fiance Rebecca Konstantinou told the court she had a $20,000 surety to secure his release on bail, which was funded from her own savings and from "family and friends".
She previously worked in schools supporting children with trauma, but said she was not currently working as she cared for their two children while Sewell was locked up.
Sewell will return to working as assisting a roof plumber to support his family if he is released, Mr Dann said.
Mr Dober opposed Sewell's release, saying he was "the initiating force" behind the attack.
"It is the applicant who leads the way, leads a charge of approximately 30 people into Camp Sovereignty, saying 'let's get 'em'," he said.
"That by itself places him in a different situation of seriousness to the others."
The prosecutor said the trial delay was not unusual and Sewell's serious role in the incident could see him jailed for close to the 10-year maximum.
The attack on Camp Sovereignty came a day before the 32-year-old was due to attend court over targeted threats to expose a police officer and his wife's personal information, for which he was later found guilty.
Sewell was remanded in custody until Thursday, when Justice James Elliott will hand down his decision on the bail application.
