Wiradjuri elder Aunty Gail Manderson, whose experiences with racism go back into her childhood, said the messages from rallies like the planned Wagga one were important.

"We are all human beings and it doesn't matter what colour you are, you should be treated the same. But we are not," she said.

Aunty Gail, 68, who was raised by white parents after being adopted at birth, believes Indigenous Australians are still dealing with impact of the Stolen Generations.

"If you're taken away from your family and you grow up without love - and told your family don't want you - you don't know how to show love," she said.

"The damage is done and it becomes a Catch-22 that goes on and on and on. I was lucky to be adopted by a loving family."

Aunty Gail is concerned about the number of Indigenous deaths in custody and would like to see wider use of Koori courts.

"A lot of our kids are getting into trouble and they are ending up in juvvie. We've got to stop it there," she said.

"We need respect. The police have got to respect us and we've got to respect the police."

Lawrence Barlow, a Condobolin-based busker, who has brought his performance to Wagga's streets, said he is still judged by the colour of his skin, something that has been happening for too long to Aboriginal Australians.

"Sometimes I only walk down the street and people walk on the other side of the street to me, even today. Kids do that too and that's sad because they've got that from older people," the 57-year-old said.

Mr Barlow is hoping rallies like the one scheduled for Wagga on Saturday will help build greater understanding across the whole community.

"It's about acknowledging each other and becoming a bit more connected with each other," he said.

Wagga Indigenous artist Tyronne Hoerler, who is planning to attend the rally with his family, believes a quick look at social media shows that racism still exists.

"The rally is a good community thing, so everyone gets together and realises what's really special to us," he said. "We're all human and we should all just walk the path together.

"I think the more people that get down there, the more support and the more love, the better."

Mr Hoerler said he believed racism was often taught.

"No one is born a racist," he said.

Member for Wagga Joe McGirr has also backed the rally, which begins at 10am and will now start at Bolton Park and move down Baylis Street to the Wagga amphitheatre.

"I think the important thing is that we do need to walk together and we need to work together," he said.
