The petition demands that the attack be prosecuted as a hate crime, that a full inquiry be launched into police failures on the day, and that decisive action be taken to ensure such violence is never allowed to happen again.

The call is backed by 21 members of the federal crossbench, who recently jointly wrote to the Albanese Government, Victoria Police, the Australian Federal Police, and the Offices of Public Prosecutions urging authorities to investigate and prosecute the attack as a hate crime and act of terrorism.

Despite the clear racial hatred and white supremacy driving the attack, police have refused to investigate it as a hate crime, laying only minor charges that fail to reflect the gravity and motivation of the violence.

Senator Thorpe said the overwhelming public and crossbench support shows that further action is needed to stamp out white supremacist violence in this country.

Quotes attributable to Lidia Thorpe, Gunnai, Gunditjmara and Djab Wurrung independent Victorian Senator:

"In August, a gang of neo-Nazis violently attacked Camp Sovereignty — a burial place for our ancestors and a sacred site of healing, culture, connection, dance and song.

"These Nazis hospitalised community members. They trampled the Aboriginal flag and desecrated our sacred site — our place of worship.

"The racial hatred and white supremacy driving this attack could not be clearer. If it were a church, synagogue or mosque, there would have been swift action from the Albanese government and authorities.

"Yet police refuse to investigate this attack on our place of worship as a hate crime. The charges they’ve laid are minor and ignore the racial hatred behind the violence. It’s just a slap on the wrist for neo-Nazis.

"This is yet another example of the colony’s acceptance and endorsement of ongoing violence and racism against First Peoples. We must not accept this.

"I thank the over 400,000 people who have signed this petition so far, and I thank the 21 crossbenchers who have stood with us in calling for justice.

"Camp Sovereignty was established by my uncle, Krautungalung Elder Robbie Thorpe, and other Elders, as a place of culture, ceremony, and healing. It is our place of worship — and it must be protected and respected like any other sacred place. First Peoples should not be treated as lesser.

"The government, the police, and the prosecutors have a duty to act decisively. This is about preventing further attacks, holding perpetrators accountable, and sending a clear message that white supremacist violence will never be tolerated."
