The democratically elected 'voice' of First Nations people in Victoria will declare on Wednesday they are ready to enter Treaty negotiations with a formal request to the independent umpire managing the negotiations.

The announcement by the First Peoples' Assembly will coincide with the official launch of the Treaty Authority — the independent umpire charged with overseeing the Treaty negotiations between the Assembly and the Victorian government.

The official notification was entered into the Authority's negotiation database before being presented at the ceremony on Wednesday.

The Treaty negotiations framework was agreed to in 2022 by the Assembly and the state government, with all parties wanting to enter into negotiations having to uphold certain standards to satisfy the Treaty Authority. This includes the Assembly and the government, and it is this process the declaration by the Assembly seeks to fulfil, with the Authority to consider the information — including by inviting community members to make comments.

Gunditjmara man and Assembly co-chair Rueben Berg said the announcement was the culmination of years of work from the Indigenous community of Victoria, which will help create a shared understanding and vision of how the journey towards Treaty should take place.

"We're proud of the inclusive structures and ways of working that we have in place to ensure the collective hopes and aspirations in our communities are well represented and that the Assembly can be the strongest advocate possible for all mob in Victoria," Mr Berg said.

The Authority is legislated through an agreement between the State of Victoria and the First Peoples' Assembly. This legislation ensures the Authority is independent and not subject to the direction of a Minister.

Furthermore, its funding is protected from the otherwise usual budget and electoral cycles.

The Assembly will negotiate a statewide treaty for "big-picture" structural reforms, including how to best transfer the decision-making powers from the Government to First Peoples, while the framework will also allow Traditional Owners to negotiate Treaties reflecting their areas specific aspirations.

There can only be one Traditional Owner Treaty that covers any particular part of the state, with a Self-Determination Fund implemented during the first term of the Assembly designed to help Traditional Owners during their own negotiation process.

Wamba Wamba, Yorta Yorta, Dja Dja Wurrung and Dhudhuroa woman and fellow co-chair, Ngarra Murray, said the public comment phase would allow Assembly members to finalise the priorities for the negotiations.

"We have been preparing for Treaties for a long time and will continue to gather feedback and input from our communities throughout the process," Ms Murray said.

"We are a diverse mob here in Victoria made up of many nations and clans and we want to make sure everyone is heard. It's an exciting time for First Peoples in Victoria, we'll be sitting down to negotiate the first Treaty in Australia."

The Treaty negotiations were previously bi-partisan before the state opposition withdrew their support - without previously notifying either the Assembly or the government - in an announcement on Sky News in January this year

The negotiations are scheduled to begin later this year.
