It's a YES! A final parliamentary vote on a bill to legalise same-sex marriage has passed.
MPs have voted in favour of making same-sex marriage legal.
The public gallery burst into an impromptu rendition of We Are Australian immediately after the bill passed.
The bulk of speeches wrapped up in the lower house late on Wednesday night, after sitting hours were extended for a second day to allow extra debate.
Further debate meant the vote was delayed until just before 6pm this evening.
All amendments were struck down and the bill has passed unchanged from the one that cleared the Senate last week.
There were 154 votes in favour and four votes against.
Those who opposed the bill were Bob Katter, Keith Pitt, David Littleproud and Russell Broadbent.
"What a day for equality, for love and respect," Prime Minister Malcolm Turnbull said after the decision was delivered.
"This is Australia - fair, diverse and filled with respect.
"This is a day for every Australian."
Royal assent from the Governor-General is now the final step in the process.
