By the Statewide Treaty Act 2025, the First Peoples' Assembly of Victoria has become Gellung Warl, established by that Act to make representations to government, and decisions on behalf of First Peoples in Victoria.

The Treaty Authority Agreement establishes the Treaty Authority. The Treaty Authority is made up of five First Peoples leaders and the members perform their role in a way that respects, observes and upholds Aboriginal Lore, law and cultural authority. This is recognised in the Treaty Authority Agreement between the Assembly and the Victorian Government.

The Treaty Authority Agreement has been amended to reflect what has been agreed in statewide Treaty negotiations. The purpose of the Agreement is to establish the Treaty Authority by agreement between the Aboriginal Representative Body and the State of Victoria in accordance with the Act.
