Up bright and early on a Saturday, "The Daniels" - Daniel Barnett and Daniel Gray-Barnett - are wasting no time in lodging their intent to marry.
They are the first same-sex couple to do so at the NSW Registry of Birth, Deaths and Marriage.
"We didn't think we'd legally be able to get married this early, this soon in our lives, so it's really nice to be doing it,” Mr Grey-Barnett told SBS News.
"It's a relief. It's been pretty stressful the last six to 12 months getting through all of this. The whole postal survey thing, not nice, no one wanted to do it," added Mr Barnett.
It became official on Thursday when parliament passed the same-sex marriage bill following a marathon debate.
“I watched parliament for the whole day for the first time in my life," said Mr Barnett.
"It was a long day but it was a good feeling."
30 days' notice required
The law was enacted overnight but couples seeking to marry must give a month's notice.
It's the reason many, like Clare Jacobs and Valeria Ballantyne – the first female couple to register in New South Wales - are getting in early.
“As soon as we found out it's legal, it can happened, we got in straight away. We want to get it done," Ms Jacobs told SBS News.
The pair, who've been together for seven years already, consider themselves married following a commitment ceremony last year.
But they are thrilled to know their marriage can now be legally recognised.
"We feel like we're married anyway, this is just the formality and then we can move on," said Ms Jacobs.
"Yeah, (it's) about time,” added Ms Ballantyne.
It's been a long time coming for same-sex marriage couples and, with that in mind Amanda Inna, from the NSW Registry of Birth Deaths and Marriage, made sure they were well prepared.
“Because of the changes in the Marriage Act we thought that we’d just let a couple of other staff come in today, just in case anyone from our community popped in to do a notice of intent today," said Ms Inna.
New definition of marriage
As of today, both same sex and straight couples registering to marry will fill out a completely new form.
New intended marriage forms include the heading Party 1 and Party 2 instead of Bridegroom and Bride, with a description of party section offering three options: groom, bride and partner.
As well, there are three boxes for gender: male, female and x - which is described as "determinate, intersex or unspecified".
Ms Jacobs said the changes are a significant step.
“We actually got one (a form) last night and it said 'Bride and Groom' and this morning they gave us the right one, it says partner and partner so it's huge, it's great!"
Those who register today will be eligible to marry from January 9.
It will be just in time for "The Daniels", who plan to tie the knot shortly thereafter.
“We have already, previously had a wedding ceremony - obviously not legal," said Mr Barnett.
“It was on the 30th of January about three years ago so we wanted to do it on the same day of that ceremony."
January filling fast
For many celebrants, like Sydney-based Michael Teulon, January is filling fast.
“Just in the last day, there's been a lot of couples out there, same-sex couples who are jumping at the opportunity to take advantage from the 9th of January to get married," he told SBS News.
He said just this morning a one couple booked a 6am ceremony on January 9th.
And it's not just same-sex couples getting in early.
“I've also had a rush from straight couples wanting to get married because I think they're getting caught up with the rush factor and concerned that unless they book and get things sorted at their receptions, they may be pushed out of the market by same-sex couples," said Mr Teulon.
