So far there have been proposals when the result of the postal survey was announced, and another during the House of Representatives debate on the bill to legalise same-sex marriage.
Let's take a look at when you can expect to see the first marriages start to take place.
What's the date of Australia's first same-sex weddings?
The first legal same-sex weddings in Australia could happen about January 8, 2018.
Why is early January, 2018 our best case scenario?
The House of Representatives passed the same-sex marriage bill today.
That means the Governor-General could ratify the law from tomorrow, making same-sex marriage legal. That would meet Prime Minister Malcolm Turnbull's hope to get it done by Christmas.
There's still a one-month wait
If you want to get married right now, you have to lodge a Notice of Intended Marriage form with your celebrant or minister at least one month before you tie the knot.
So if we're working off a December 8 date, the first legal same-sex weddings in Australia could happen around January 8, 2018.
And Attorney-General George Brandis agrees.
Previously, he told AM he expected the "beginning of next year" was when we'll see the first same-sex weddings.
Can I book my same-sex wedding now?
There's nothing stopping you from booking a wedding for 2018.
FWIW, the Attorney-General's office has previously confirmed with the ABC that Notice of Intended Marriage forms could not be lodged until the same-sex marriage law was passed, which happened today.
But it's always best to clarify all of the details with your celebrant or minister.
