After a campaign that has felt like aaaages,cerita lucah 2020 Australia's same-sex marriage postal survey is entering its final days.

Twitter, one of a large handful of major companies that have publicly pledged support for the legalisation of same-sex marriage in Australia, is giving the "Yes" vote one final push. On Tuesday, they unveiled a special emoji for the marriage equality campaign.

The emoji features the "Yes" logo which has been the cornerstone of the pro-marriage equality campaign, when users tweet any of these hashtags: #EqualityCampaign, #MarriageEquality, #VoteYes, #PostYourYes, #PostYes, and #YesForEquality.

Here's how the logo appears on Twitter — it however won't display outside the platform.

As of last week, two-thirds of Australians have sent back their postal survey forms, according to the Australian Bureau of Statistics. It's a non-binding, non-compulsory postal "vote" asking the question, “Should the law be changed to allow same-sex couples to marry?”

However, the pro-marriage equality campaign is concerned about complacency, especially from young voters who are more likely to vote "Yes" for allowing same-sex couples to marry.

According to polling by Newspoll, 66 percent of those between the ages 18-34 support same-sex marriage, but only 57 percent of them had posted their voting form. That's in contrast to 74 percent of over-65s who've sent in their vote, where the "No" vote is stronger. A shiny new Twitter emoji could sure do the trick spreading the word to this younger target demographic.

The due date for sending postal votes is Oct. 27, so if you're Australian and haven't sent yours in already, time is really ticking.
