Malcolm Turnbull's proposed plebiscite on equal marriage was defeated 29-33 in the Senate late on November 7.
Months of speculation and political talk culminated in Labor, the Greens, the Nick Xenophon Team and Derryn Hinch combining to defeat the proposal.
Chair of Australian Marriage Equality Alex Greenwich said supporters of same sex marriage should refocus efforts on a direct vote in Parliament to change the Marriage Act.
"We know that a majority of Australians, indeed a majority of parliamentarians, support this reform. We hope that we can all work together to finally get this through Parliament.”
