Australian rock band Midnight Oil led by Peter Garrett have lent their voice to the 'Yes' campaign.

The Oils have produced, recorded, and paid for a radio advertising campaign explaining why people should reject "bullshit scare campaigns" and vote yes to a Voice to parliament in the October 14 referendum.

One advertisement launched on Monday features Garrett telling people on behalf of the band to find out more about the official 'yes' campaign, set to the music of the band's hit Power and the Passion.

"Of course YOUR vote is totally up to you but don't get sucked in by all the bullshit scare campaigns. If you don't know, find out," he says.

In a post on their social media channels, the band said "don't let anyone treat you like a mug", while Mr Garrett dissected some of the misinformation in a series of YouTube videos.

"You know, your land's gonna get taken away from you, or your house... we're upending Parliamentary democracy. All of these things are clearly not true," he said.

"Let's deal with the facts here."

Mr Garrett also spoke on the arguments of the 'progressive No' bloc who argue the voice is an inadequate proposal to deal with the issues of land rights, sovereignty and closing the gap.

"The majority of Indigenous Australians want to see the voice happen," he said.

"Always there's going to be a bit of disagreement, but for some of those people, the voice is so modest, that they'd like to see more. The voice is a good first step for all of us."

The Oils have been campaigners for Indigenous causes since the mid-1980s and are also renowned for their independence and active support of the environment.

The band famously appeared at the closing ceremony of the 2000 Sydney Olympics emblazoned with the word 'Sorry' - representing an apology to the Stolen Generations, which the then Prime Minister John Howard had ruled out.

In 2020 they collaborated with First Nations artists on a chart topping album called "The Makaratta Project", their first release in 14 years that debuted at no.1 on the ARIA charts and sought to elevate the Uluru Statement From The Heart.

That statement underpins the current Indigenous-led campaign for constitutional recognition and the enshrining of The Voice so that Indigenous Australians can be consulted on matters directly affecting them.

Mr Garrett is a long-time advocate and campaigner on a range of local and global issues, and served as a cabinet minister in the Rudd/Gillard Labor governments from 2007-13.

Last month he joined other Australian heavy-hitters from the Australian music scene including Paul Kelly and John Butler, in a series of free gigs across the nation linked to Yes23's Walk For Yes events promoting the voice to parliament.

Mr Kelly played the song If Not Now, penned in support of the referendum.
