Binary Australia formerly the Marriage Alliance, is an Australian anti-trans and anti-gay marriage lobby group based in Sydney, New South Wales. According to the group's website, it "is an independent alliance bringing together individuals and organisations supporting a common cause. We exist to voice the opinion of the silent majority of Australians that respect same-sex attracted people, but do not want to change the current definition of marriage." They campaign against same-sex marriage.
In November 2018 the group rebranded as Binary Australia with the stated aim to "carry on the fight for traditional values that celebrate the inherent differences between boys and girls, men and women". The Global Project Against Hate and Extremism (GPAHE) released a report on 5 October 2022, in which it classified Binary Australia as an "anti-LGBTQ+" group.
Campaigns Marriage Alliance partnered with the Coalition for Marriage and other groups opposed to same-sex marriage, to campaign for a 'No' vote in the 2017 Australian Marriage Law Postal Survey.
