The singer’s boyfriend says the couple will not marry until all Australians can.

Kylie Minogue’s British fiance says the couple won’t get married until same-sex marriage becomes legal in Australia.

The pair announced their engagement earlier this year – but Joshua Sasse says they will not walk down the aisle until all Australians can do the same.

Minogue has been vocal in her support of the “Say I Do Down Under” campaign – which just so happens to be headed by Sasse.

Launching the campaign, Sasse said the pair want to wed in Melbourne, “but we will not get married until this law has passed in Australia”.

“When I found out that gay marriage was illegal in Australia, I was astounded,” he told Australia’s Seven Network.

“I simply can’t fathom on any level, whether it’s moral or religious or anything, 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.”

Minogue was quick to share Sasse’s sentiments online, as she once again tweeted her support for the campaign.

“We can say ‘I Do’ when you can too!” she wrote.

The pop star previously explained her fiance’s passion for the issue, saying: “He’s so adamant to fight for gay rights in Australia and it’s coming from the most genuine place.

“He just can’t fathom that same-sex marriage hasn’t been legalised and of course I back him up on that, we are waiting for it to happen.”

The Australian government has proposed holding a public vote on same-sex marriage in February 2017.

The country’s Prime Minister Malcolm Turnbull wants to put the issue at a public vote at a cost of $200 million – despite opponents saying the move is unnecessary and expensive.
