Public forum

Public opinion has changed dramatically on same-sex marriage in the United States and Australia over the past decade. This shift in attitudes has been recognised in the United States with changes to the law – through a mix of legislation, special ballots and court cases. In Australia, this issue is now playing out through a postal survey that will guide the next steps of our federal parliamentarians.

Polling experts from the United States Studies Centre at the University of Sydney discussed the latest survey data to understand the possible outcomes of Australia's unprecedented same-sex marriage vote, the campaign tactics used, and what the US experience tell us about what to expect in Australia.

Hosted by USSC CEO Professor Simon Jackman, the event gave students, academics and polling enthusiasts the chance to unpack the campaign, the response and the data on public opinion.
