Cheers and applause broke out as lawmakers voted in favor of the bill following hours of debate and emotional speeches at Parliament House in Canberra.
“This is Australia: Fair, diverse, loving and filled with respect for everyone,” said an effusive Prime Minister Malcolm Turnbull, as he introduced the bill for a final vote.
“This is a great day, it belongs to every Australian.”
The bill passed its third reading with only four members of parliament in opposition.
The parliamentarians who voted in favor of same-sex marriage took time to let the jubilant moment sink in, celebrating with hugs, handshakes and proudly sporting rainbow-colored clothing.
In a particularly poignant moment, the ministers on the House floor and guests in the gallery began singing “I am, you are, we are Australian.”
The move follows a two-month national postal survey that showed 61% of more than 12 million respondents were in favor of marriage equality.
The country is now the 24th in the world to allow same-sex couples to marry, according to Pew Research.
Australia’s first same-sex weddings will not take place until at least January, however, due to a longstanding requirement for all Australian couples to provide a full month’s notice of their intention to get married.
