If the Yes23 campaign fails to reverse what the polls are saying and fails on October 14, opposition leader Peter Dutton says he would hold a second referendum solely to enshrine First Nations recognition in the Constitution.

The announcement comes as the ‘yes’ campaign secured permission to use John Farnham’s famous anthem You’re the Voice in a promotional film due to be released on Sunday.

The Uluru Dialogue – the organisation dedicated to advancing the Uluru Statement – is launching the film, which will pair the famous song with transformative moments in Australian history.

The opposition is against enshrining a Voice to parliament, which would provide advice on issues affecting Aboriginal and Torres Strait Islander people, but supports constitutional recognition.

Mr Dutton told Sky News he would be prepared to hold another referendum on the matter if elected.

“Yes, I believe very strongly that is the right thing to do,” he said on Sunday. “But enshrining a Voice in the Constitution is divisive.”

‘Fear campaigns’

He said it would split “the country down the middle” and fail to provide practical outcomes.

Debate on the matter has kicked up a gear since the Prime Minister last week announced October 14 as the date for the referendum.

On Saturday, Mr Albanese took aim at “fear campaigns” about the voice.

“This campaign is going to be won by one-on-one conversations with people, making sure that the fear campaigns which are there (are) no more real than the fear campaigns that were there about the Apology to Stolen Generations, about Mabo, about native title, about marriage equality, about all of these issues,” he told supporters in Canberra.

The referendum’s success depends on majority support across the country and in four of six Australian states.

The question to be put in the referendum is: “A Proposed Law: to alter the Constitution to recognise the First Peoples of Australia by establishing an Aboriginal and Torres Strait Islander Voice. Do you approve this proposed alteration?”

If the referendum vote is successful, the government will then design the specific form of the voice, which will be implemented via legislation passed by and debated in parliament.
