Australian Marriage Law Postal Survey

The Australian Marriage Law Postal Survey was a national opinion poll conducted in 2017 to gauge public support for legalizing same-sex marriage. Eligible Australians received a survey via mail, asking whether they agreed with changing the law to allow same-sex couples to marry. Participation was voluntary, and the results informed Parliament’s decision-making. The survey found that 61.6% supported legalizing same-sex marriage, leading to legislative change that authorized same-sex marriage nationwide. It was a non-binding, consultative process aimed at reflecting public opinion on this social issue.
