Bundjalung Widubul-Wiabul woman Vanessa Turnbull-Roberts has called on non-Indigenous people from both sides of the Voice debate to call out racism when they witness it.

Appearing on the ABC's Q+A programme, Ms Turnbull-Roberts, a lawyer and human rights advocate, said Indigenous people were suffering with the referendum process.

"It's been hard on our communities," she said.

"When you're already a group that's targeted and marginalised, and then you are that national conversation, the impact that it has on the ground for our communities is detrimental."

She called on anyone watching to talk to community and not deal with things alone.

"(If) you are struggling, lean on community. Whether you are Yes or you are No, or you're 'I Don't Know', you have a community, you are loved," she said.

"There is no need to feel worried about expressing what you are going through."

She said non-Indigenous people had a responsibility to call out racism, recalling witnessing racist sentiments from No supporters at a Voice debate at a university go unchallenged, from both Yes and No supporters.

"Not one of those people stood up and said: 'Hey that's not on. We don't do this,'" she said.

"As a non-Indigenous person, as a settler on these lands, remember you have a responsibility. And that means if you see racism, hear racism, you call out racism —period," she said.

Ms Turnbull-Roberts - a survivor of Out of Home Care, who was forcibly removed at the age of 10 from her family - used the earlier part of the show to discuss her position on the Voice, on which she said was undecided.

"I'm not a certain 'no', I'm very much undecided like many of my peers and my sisters and brothers within community," she said.

She also called out the campaigning, noting that not all the people voting no were the same and held the same views.

"We need to recognise there's three campaigns," she said.

"There's very much a yes side, a no side and a very strong racist no side that's pushing an agenda that's quite harmful to our communities and it's quite harmful around non-Indigenous people pushing that political discourse within our communities as well."

In response to a prompt on what it would take for her to vote yes, she said she would need to see a real commitment from the government that the Voice would have real and meaningful impact, power and the ability to enact substantial change.

"What would actually see me be a complete yes… is our government of the day proving to our people to demonstrate that there actually is substantial power within this," she said.

"We're told every single day: 'It holds no power, it's just advisory, shh, settle down, it's just consultancy, relax everybody.

"But that (consultancy) doesn't have to be listened to, and as someone on the receiving end - and as a survivor of family policing here in this country - I don't want to hear more crumbs [and] discussions anymore. I don't want to hear more advisories. I want to see real change for my people."

Ms Turnbull-Roberts argued that rhetoric was becoming tiresome without action.

"We hear this all the time, one bit of progress is better than no progress at all but we have been told this rhetoric all the time," she said.

"We have been told…after one death in custody, two deaths in custody, three, there'll be no more deaths in custody. And then we wake up and there's another Aboriginal death in custody.

"We say there's going to be no more child removals, yet we carry one of the most highest rates of child removal here in this country that disproportionately impacts First Nations people."

Fellow panellist, Gunai Kurnai man Darcy McGauley-Bartlett, said he had been intending to vote yes - after seeing the work undertaken by state and regional voices - but after listening to Ms Turnbull-Roberts, he too wanted more assurances from the government that the process would lead to meaningful change.

The 2023 Victorian Young Australian of the Year said on issues such as deaths in custody and children in out-of-home care, he wanted to see the government actually implement change after consultation, rather than receiving reports and saying, "good point," then continue to ignore.

"I totally agree that we have not been listened to for a very long period of time," he said.

"It's (about) moving past the acknowledgements and good intentions and creating that action for systemic and sustainable change for my community.

"If this Voice is going to create that change … we will see better outcomes for Aboriginal and Torres Strait Islander people, if we are listened to."
