(CNN)Australia is the closest it has ever been to legalizing same-sex marriage.
On November 15, the Australian Bureau of Statistics revealed 61.6% of Australians had voted in favor of legalizing marriage equality as part of a national postal survey.
In total, 79.5% of Australian voters took part in the voluntary vote.

So why is the issue so divisive in Australia?
