Australians have had their say, with 61.6 per cent of the nation voting Yes to legalising same-sex marriage.
The final count was 7.8 million responses in support of same-sex marriage, and 4.9 million against.
Australian statistician David Kalisch said the final number of responses was 12,727,920 people, representing 79 per cent of eligible Australians.
“This is outstanding for a voluntary survey and well above other voluntary surveys conducted around the world,” he said.
“It shows how important this issue is the many Australians.”
Mr Kalisch noted participation was strong across every state and territory except in the Northern Territory, where only 58.4 per cent of eligible people responded.
Participation in the survey was over 70 per cent in 146 of the 150 electorates.
“The participation in the survey were slightly higher in older ages and slightly lower in younger age groups but not markedly so,” Mr Kalisch said.
“It is worth noting our youngest on the electoral roll, the 18- and 19-year-olds, responded strongly, with around 78 per cent participation.”
Prime Minister Malcolm Turnbull addressed the nation minutes after the result was announced, promising to bring the same-sex marriage bill to a vote in Parliament before Christmas.
“They have spoken in their millions and they have voted overwhelmingly Yes for marriage equality,” he said.
“They voted Yes for fairness, Yes for commitment, Yes for love.
“And now it is up to us here in the Parliament of Australia to get on with it, to get on with the job the Australian people have tasked asked to do and get this done. This year, before Christmas — that must be our commitment.”
