Update, 4.30pm: Dawson MP George Christensen says he is "absolutely disgusted" by the "politically correct Canberra mob" who were vocal in supporting the same-sex marriage amendment today.
In a fiery speech in parliament, Mr Christensen called out those who supported the "religious liberty amendment" to the same sex marriage bill for their "rapturous applause".
"The amendments that have been put forward by the member for Mallee - go very much, again, to the heart of religious liberty that we've seen voted down again and again today in this house," Mr Christensen tells Canberra.
"And we've seen cheers from the gallery … cheering for the erosion of religious liberty … cheering for the erosion of religious liberty," he said as applause rang out above him.
"There they go, cheering again, cheering again, when I'm specifically saying eroding religious liberty, they support that.
"That is the voice of tolerance today, and I am disgusted. I am absolutely disgusted that we are going down this track."
Watch his outburst here:
Earlier: SAME-sex marriage is set to pass the parliament later today after MPs knocked back a series of last-minute changes to the historic bill.
Dawson MP George Christensen has taken to Facebook to confirm that he will not be voting with his electorate's Yes.
Mr Christensen came under fire when he first said he might abstain from the vote, rather than commit to a position he did not agree with.
At the time he denied it was a backflip, instead saying it was because he wanted protections for conscientious objectors, parents and religious objectors.
"The House of Representatives has just voted to not allow civil celebrants - even those who are pastors - to exempt themselves from having to perform marriages for same sex couples," he wrote on Facebook today.
"They've effectively ensured a lot of people who would otherwise vote for legislation to allow same sex marriage can no longer vote that way, myself included.
"It also looks like they are going to vote down the right of churches to refuse to hold same sex marriages and marriage celebrations in church halls and the like.
"If churches and pastors can't even have freedom to not be party to something that is against their fundamental beliefs then neither can anyone else."
Just over half the people who voted in the Dawson electorate backed same sex marriage, 55.1%.
Malcolm Turnbull refused to cancel Question Time today to continue the debate on the three remaining amendments.
Opposition leader Bill Shorten had made the request but Mr Turnbull refused, saying both the Government and Opposition were accountable during the session.
But he did agree to end Question Time at 3pm, cutting the session short by about 15 minutes.
Parliament has just a few scheduled hours of sitting time left to finish the debate and pass the legislation before it goes into overtime.
It comes after Queensland crossbench MP Bob Katter delivered a bizarre, rambling speech on same-sex marriage in the House of Representatives last night.
Mr Katter spoke about everything from slavery to "boys in dresses", Christianity and Gianni Versace, while making wild accusations that gay people were "murderers" and "responsible for giving AIDS" to society through donating blood.
He also said he wasn't anti-homosexual.
Mr Katter was one of the last MPs to speak on the bill. About 120 others have spoken in the past three days.
