Binary Australia formerly the Marriage Alliance, is an Australian anti-trans and anti-gay marriage[2][3] 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."[4] 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".[5][6] The Global Project Against Hate and Extremism (GPAHE) released a report on October 5, 2022, in which it classified Binary Australia as an "anti-LGBTQ+" group.[7]
They have conducted an extensive and controversial anti-gay marriage campaign in the media and on social media:
Ads initially accepted for broadcast by Channels 7 and 10, with management of those channels later deciding to not do so,[8] were subsequently, and controversially, broadcast by Foxtel.[9]
a 'rainbow noose' advert "claiming that same-sex marriage will increase suicide because people who are against it will be bullied over their views if it becomes law".[10]
a YouTube presentation 'It's not as simple as you think'.[11]
