"There are chances of a Melbourne wedding, [but] we will not get married until this law has passed in Australia,” Minogue's fiancé, English actor Joshua Sasse, told Network Seven on Thursday.

"When I found out that gay marriage was illegal in Australia, I was astounded," Sasse said.

"I simply can't fathom on any level, whether it's moral or religious, that I have the right to get married and to marry the person that I love and that somebody else doesn't because of their sexual orientation," he continued.

Australia's government has put forward the idea of a public national vote on same-sex marriage in February 2017.

The couple are actively involved in the 'Say I do Down Under' campaign for same-sex marriage in Australia.
