The vote on October 14 is set to decide whether to establish a body called the Aboriginal and Torres Strait Islander Voice, recognising First Peoples in the written Australian Constitution.

It is set to be the first referendum in Australia since 1999 when it voted against becoming a republic, and only eight of the 44 such ballots in the country have passed.

To pass, a national majority of votes is required and a majority in at least four of Australia's six states.

However, recent polls have the referendum on course to fall short, with a Sydney Morning Herald report showing only majority support in the island state of Tasmania.

Queensland, of which 2032 Olympics and Paralympics host Brisbane is capital, is among the states with the lowest level of support for the referendum.

However, the Organising Committee for the Games has backed the proposal.

In a statement shared by President Andrew Liveris on X, formerly Twitter, the Board said it had discussed the referendum and is "proud to support" it, with Queensland "home to two of the world’s oldest living cultures, Aboriginal and Torres Strait Islander peoples".

Brisbane 2032 said it had taken guidance from First Nations representatives on the Board, the Australian Olympic Committee and its Athletes' Commission and Indigenous Advisory Committee, and Paralympics Australia.

It claimed prioritising First Nations in its legacy plans for the Games aligns with the International Olympic Committee's New Norm and Olympic Agenda 2020 strategies, and encouraged Australians to fully research the proposal before voting on October 14.

"While we as the Board of the Organising Committee have formed the collective position to support The Voice, we respect that there are diverse points of view and everyone’s right to take their own position," Brisbane 2032 said.

"We encourage everyone to learn about this referendum and engage meaningfully in the process.

"Brisbane 2032 is at the start of our reconciliation journey with First Nations peoples.

"Next year, we will deliver our first Reconciliation Action Plan, which will further define our intent to partner with First Nations peoples in the delivery of the Olympic and Paralympic Games.

"We look forward to undertaking this process hand-in-hand with First Nations peoples of Brisbane and Queensland over the coming decade."

The debate has proved increasingly divisive in Australia, and there are concerns over the impact of misinformation.

Prime Minister Anthony Albanese has described the referendum as "a once-in-a-generation opportunity for real, overdue and much-needed change", while opponents claim the new body will have too much power.
