The survey was taken between the 1st and 7th of August, with results weighted by gender and age, based on Australian Bureau of Statistics data, resulting in an effective sample size of 548 and a margin of error of ±4%.

Key Findings:

• Around two in five South Australians (43%) say they will vote “Yes” at the referendum, with a similar proportion (39%) saying they will vote “No”, and one in five (18%) saying they are unsure
• When the leanings of those who are unsure are incorporated, a majority of South Australians (52%) are inclined to vote “Yes” at the referendum
• A majority of South Australian women (56%) are inclined to vote “Yes”, while a majority of South Australian men (52%) are inclined to vote “No”
• South Australians under the age of 40 were the most inclined to vote “Yes”, while those aged 60 and over were the most inclined to vote “No”

“Our research shows that, with a majority of South Australians currently inclined to supporting the Voice at the upcoming referendum, it is young women who are leading the way and are most likely to be intending to vote Yes,” said Noah Schultz-Byard, South Australian director at the Australia Institute.

“If young South Australians want the referendum to succeed, it’s clear that they need to talk to their parents and grandparents about why they so strongly support the Yes vote.

“Political division on this issue is clearly having an impact on how South Australians intend to vote, with a majority of Labor and Greens supporters intending to vote Yes and a majority of Coalition and One Nation supporters intending to vote No.

“As the only jurisdiction with a legislated First Nations Voice to Parliament, and as a potential swing state, South Australia will likely be one of the key battlegrounds ahead of the upcoming referendum.”
