An indigenous Voice to parliament would bring people together, not divide the nation, the prime minister has said, just days ahead of polling day.

There was a lot of misinformation about what the voice would do and what it would cost, Anthony Albanese said on Friday.

“This will actually save money,” he told Brisbane radio station B105.

“What you’ll get if we listen to people is more efficiency, you’ll get the dollars going to where they should go.

“This is about helping a group of Australians – three per cent of Australians – it won’t have a direct impact at all on non-indigenous Australians directly.”

Asked by a listener whether creating a specific body for Indigenous Australians in the constitution would divide the nation, Mr Albanese said it would not.

“The idea of this is to work together to bring the country together,” he said.

“If it comes up with a good idea, then governments should adopt it… when we listen to people who are directly affected by an issue, we get better outcomes.”

But Opposition Leader Peter Dutton continues to argue the Voice proposal lacks detail and that people who want to help indigenous Australians will be forced to vote ‘no’ if their questions go unanswered.

“It just makes people, I think, more reluctant – tradies and others who are saying, ‘I want to help indigenous people but the prime minister is not putting the detail out there, so I don’t understand it, I am not voting for it’,” he told Nine’s “Today” program.

If the referendum is successful, the Voice would be a permanent but non-binding advisory body that would be able to make representations to the parliament and the government.

Meanwhile, former High Court chief justice Robert French will address the National Press Club on Friday on the Voice.

Mr French has previously dismissed arguments a Voice could be subject to multiple legal challenges, declaring it “constitutionally sound”.

He’s also labelled legal arguments around the Voice as “a shadow which distracts from the substantive”, stating the High Court would likely consider the intent of the parliament when making any rulings.

“Put shortly, the Voice provision provides for the recognition of Aboriginal and Torres Strait Islander peoples, not as a race but as the First Peoples of Australia,” he told parliament earlier this year.

“That provides a significant shift away from the existing race-based legislative power that the Commonwealth has.”

Some state and territory leaders will also gather in Adelaide in a show of unity for the Voice.

South Australian Premier Peter Malinauskas will host his counterparts – NSW Premier Chris Minns, Victoria’s Jacinta Allen, NT Chief Minister Natasha Fyles and WA Premier Roger Cook – alongside Yes23 campaign director Dean Parkin.

As well, former Tasmanian Liberal premiers Peter Gutwein and Will Hodgman, be at Parliament House in Canberra on Friday to make the case for “yes”, alongside their Labor counterparts Michael Field, David Bartlett, Lara Giddings and Paul Lennon.

The Voice referendum will be held on October 14.
