Liberal MP Tim Wilson has proposed to his partner Ryan during a speech to the House of Representatives.
This comes as the same-sex marriage bill is set to be put to the House of Reps in order to legalise gay marriage in Australia.
"And with the indulgence of the Speaker, the person I have to thank most is my partner, Ryan," Mr Wilson said.
"You've had to tolerate more than most, because you have had to put up with me.
"This debate has been the soundtrack to our relationship. We both know that this issue isn't the reason we got involved in politics - give us tax reform any day.
"In my first speech, I defined our bond by the ring that sits on both of our left hands, and that they are the answer to questions we cannot ask.
"So there's only one thing left to do. Ryan Patrick Bolger will you marry me?"
And Mr Bolger said yes.
Debate on the bill is expected to be over by Wednesday or Thursday this week and is expected to pass easily.
