Uluru Statement from the Heart architects the Uluru Dialogue have unveiled John Farnham's iconic Australian ballad 'You're the Voice' as an anthem for their Yes campaign.
The organisation launched a three-minute ad under the same name as the song for online, and shorter cuts for television, on Sunday.
It's the latest instalment of the Uluru Dialogue's 'History is Calling' campaign, a series launched in September last year.
The video follows an Australian family witnessing momentous points in the nation's history through recent decades, Mr Farnham's song playing out over the 1967 referendum, the Mabo decision, America's Cup victory, the Uluru handback, Cathy Freeman's Olympic gold medal run, 1996 gun reform, and Kevin Rudd's 2008 apology speech in Parliament.
The 2017 marriage equality plebiscite - Australia's most recent non-election national vote, is included.
Uluru Dialogue co-chair Professor Megan Davis told National Indigenous Times the short film is inspired by previous and national discussions and innovations in public policy and law reform.
"Sometimes those decisions have been scary and anxious for the nation and we've debated it, and we weren't sure, but it's made the country a better place," she said.
"It's made the country a safer place and a more inclusive place. And then the moments that we now celebrate, and that's really what the ad is about."
Fellow Uluru Dialogue co-chair Aunty Pat Anderson said previous examples of change set the precedent as "archival proof" of people moving to be "on the right side of history".
It's the first time 'You're the Voice' has been granted for use in a commercial by John Farnham.
The now 74-year-old said the permission was given with purpose.
"This song changed my life. I can only hope that now it might help, in some small way, to change the lives of our First Nations Peoples for the better," he said.
Kaytetye man and award-winning feature director and cinematographer Warwick Thornton directed the video, delivered by creative agency The Monkeys, as part of digital agency giants Accenture Song.
Professor Davis said it serves as a major piece of their campaign, otherwise focused on grassroots efforts.
The group has travelled the nation engaging with communities for discussion and yarning circles in the lead up to the referendum.
"It's just about the facts, and why we wanted a Voice and what process was it Uluru, and proving pretty successful in areas with large undecided and no votes," Professor Davis said.
