A former One Nation politician has said Aboriginal culture should have "died out with the Stone Age".

Conservative radio host David Oldfield's comments were aired last night on SBS' First Contact program, which analyses indigenous culture by getting white personalities to experience the trials of Aboriginal life.

"It's not actually good for Aborigines to remain Aborigines. They should be Australians. And you just naturally let it die out. I mean frankly it should have died out. Like the Stone Age died out," Oldfield said.

"Is there something celebratory they lived in the Stone Age longer than anybody else? I can't see it."

During last night's first episode of the series, Natalie Imbruglia, Tom Ballard, Ian 'Dicko' Dickson, former Miss Universe Renae Ayris and actor Nicki Wendt were invited to join an indigenous family in a traditional ceremony.

Oldfield refused to participate.

Timmy 'Djawa' Burarrwanga, who helped instruct the group, questioned the radio host's motives.

"David can I ask you one question? Are you not actually accepting the oldest culture in this country? You're not accepting this. I need to know what's bothering you," Burarrwanga said.

"I accept this dominant world. I accept your law - your system. And you know, this country is so racist. In the constitution it's so racist. We're not actually in the constitution. It doesn't recognise Aboriginal people."
