Kylie Minogue and fiance Joshua Sasse vow not to marry until same-sex marriage is legal in Australia

Singer Kylie Minogue and her British fiance Joshua Sasse have vowed not to tie the knot until same-sex marriage becomes legal in Australia.

The 48-year-old star announced her engagement to the actor in February, after the couple met on the set of his TV series Galavant.

But now, Sasse, 28, has revealed that the couple have decided to delay their wedding until same-sex couples in Australia have the same rights that are enjoyed by gay couples in Britain.

Speaking to Australia's Network Seven, Sasse said: "There are chances of a Melbourne wedding, but me and Kylie have talked about it, and we are not comfortable getting married until this law has passed.

"That is something that we've talked about and decided on. Why should we? Why is it fair? Why are we more important than anyone else? It's not right and something's got to be done about it."

The actor said he was "astounded" to discover gay marriage was not legal in Australia.

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

A campaign to change the same-sex marriage law in Australia has been backed by a number of other high-profile personalities, including Dolly Parton, Scissor Sisters' singer Jake Shears and actress Margot Robbie.
