IT’S been months in the making, but we’re finally at the pointy end of the same-sex marriage plebiscite voting period.

The $122 million postal survey will close in less than a month, and with more than 62 per cent of Australians having returned their vote, the big question is: will it be a Yes or a No?

Of course, we won’t know for sure until the official results are tallied, but a snap poll by Roy Morgan has given us a preview of what’s likely to come.

According to their stats, it’s a resounding Yes, with 61.5 per cent of Australians in favour and just 17.5 per cent voting No.

Of that number, women were more in favour of same-sex marriage - 66.5 per cent were Yes, compared with 56 per cent of men.

State by state, Victorians are the biggest supporters with 69.5 per cent voting Yes, followed by Western Australians and Tasmanians, both with 63.5 per cent.

On the other side of the debate, New South Wales is delivering the highest number of No voters at 21.5 per cent, which is surprising given that Sydney — the home of Mardi Gras — is considered one of the most gay-friendly cities in the world.

Queensland and South Australia tied in second, each with 18.5 per cent of respondents voting No, according to the poll.

The Roy Morgan poll also shows how Australians are voting based on age, with younger people more likely to vote Yes.

More than 80 per cent of 18-24-year-olds have voted Yes, with that figure dropping to 70 per cent for 25-34 years and 69.5 per cent for 35-49 years.

When it comes to the 50-64 year category, 52 per cent have voted Yes and only 48.5 per cent of Australians older than 65 years supported same-sex marriage.

The survey closes on November 7, with the ABS to reveal the results on November 15.

Latest figures released last Tuesday showed 10 million survey forms have already been returned — up an estimated 800,000 from the week prior.

A recent Sky News Reachtel poll revealed the Yes vote is on track to win the survey.

The poll of almost 5000 people found 64 per cent of those surveyed had returned their ballot paper, and had voted yes.

Special Minister of State Scott Ryan says he expects a two-thirds return rate of same-sex marriage surveys.

“I think we could get very comfortably to two-thirds, which is an extraordinary response and a testament to the conduct of the debate and Australians’ willingness to participate in the survey,” Senator Ryan told Sky News this week.

The Equality Campaign welcomed the response rate figures, with Campaign co-chair Anna Brown saying the steady increase in survey returns is “another reminder of how much Australians care about marriage equality and how the country wants this resolved”.

Earlier this week, New Zealand’s The Project delivered an hilarious tongue-in-cheek “Open Letter to Australia” regarding the same-sex marriage debate — and it certainly pulled no punches.

“Hi Australia, this is New Zealand. It’s come to our attention that you’re deciding whether or not to legalise gay marriage right now. And as your friend, we’d like to take a moment not to make the same mistake we did,” presenter Jesse Mulligan began with a twinkle in his eye.

“Please, please vote ‘No’ to same-sex marriage.”

For those who weren’t across it — New Zealand legalised same-sex marriage back in 2013.

“Many of us were horrified,” he intoned with a straight face.

“We predicted that gay marriage would be a slippery slope — and we were right.

“It started with men marrying men and ladies marrying ladies, and before we knew it we were seeing dogs marry cats, cats marry birds, birds marry dogs and babies marry babies.

“Vote ‘No’ Australia. Stay strong. Look to your heterosexual heroes for inspiration ... And if we’re looking for straight role models, how about the band Tony Abbott suggested to replace Macklemore at the Grand Final. Now there is nothing gay about Savage Garden!”
