On the eve of the Voice to Parliament referendum, one of the co-chairs' of the First Peoples' Assembly in Victoria has penned an open letter, urging people to look at Victoria and realise it is possible to bring all three elements of the Uluru Statement from the Heart to fruition.

Wamba Wamba, Yorta Yorta, Dhudhuroa and Dja Dja Wurrung woman Ngarra Murray, who was elected as co-chair alongside Gunditjmara man Reuben Berg in July, said that the First Peoples' Assembly - Victoria's democratically elected and diverse Aboriginal representative body - has helped established a truth-telling inquiry as well as paving the way for Treaty negotiations with the state government.

"So, it's only natural that we want First Peoples in other states and at a national level, to also benefit from the pursuit of Voice, Treaty and Truth," Ms Murray said.

In noting that the Assembly voted to endorse the Yes vote, and was encouraging everyone to vote Yes, Ms Murray said it was ultimately about bringing everybody closer together.

"Everyone wants to get on with creating a better tomorrow as equals, but to do that we need to address some unfinished business," she said.

"It's not just about healing the wounds that linger from our yesterdays, because the impact of colonisation didn't just stop one morning. Rather the impacts have flown on, with disadvantage often compounding down generations and insidious forms of discrimination mutating into the structural racism our people still face today."

Her comments starkly contrast with federal opposition spokesperson for Indigenous Australians, Warlpiri/Celtic woman Jacinta Nampijinpa Price, who told the National Press Club in September, "There's no ongoing negative impacts of colonisation".

Ms Murray, whose great grandfather Pastor Sir Douglas Nicholls, called for the right for Indigenous people to elect their own representatives to federal Parliament, said the impacts of colonisation were vast.

"Being hunted off your land, herded into missions, ripped apart from your families and culture – these things have a devastating and intergenerational impact," she said.

These mirror the comments of Indigenous psychologist and Nyamal woman, Dr Tracy Westerman, who told Crikey, "There is also the erroneous idea that trauma is visible, which creates more stigma to those with trauma."

Ms Murray said too often governments have attempted to deal with issues impacting Indigenous people, without listening to them directly.

"Although many governments have attempted to address some of the issues, their efforts missed the mark every time because they failed to listen to First Peoples. They made policies and laws to us, never with us," she said.

"We must find better ways of working together to find the solutions to the challenges that still hold our people back. Here in Victoria, the shared journey to Treaty offers an opportunity to commit to a fair and respectful process for ongoing agreement making.

"It's just common sense that governments trying to make policies and programs for Aboriginal people, are always going to get better outcomes when they listen to Aboriginal people."

Highlighting the Treaty process, which has been legislated by the Victorian government and will begin towards the end of the year with an independent umpire, Ms Murray said the First Nations people were seeking "structural change" to bring decision making power back into the hands of Aboriginal people.

She noted that there was no one-size-fits-all approach, which is why traditional owner groups throughout the state will be able to negotiate their own Treaties, and why Treaty negotiations in other states will "need the years…to have the yarns, to identify the common goals and agree on a pathway forward".

"But do you know what the common element is?" she said.

"All of these efforts are underpinned by one thing – they require a willingness to listen to First Peoples. And to be heard, you need a Voice."

Ms Murray used her letter to note that there was some disagreement and consternation in some quarters of community about the impacts of the Voice, but said the vast majority of the Assembly - and community - supported a Yes vote, even if, she argued, it "might not be as strong" as some would have hoped.

"Creating a space, a democratic forum for First Peoples elected by First Peoples to distil and articulate the views of our communities, has got to be a step forward," she said.

She said it was ironic that the Voice debate has often centred on what was best for Aboriginal people, when there was a chance to enact a national representative body that could do just that and implored people to walk with Aboriginal people in Victoria and vote Yes.

"At the heart of the decision before the Australian people is a simple question – are you willing to listen to First Peoples," she said.
