"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."
Asked about the location of their wedding, Sasse told Network Seven from Vancouver: "There are chances of a Melbourne wedding... [but] we will not get married until this law has passed in Australia."
The Australian government has proposed holding a public vote on the issue next February, with voters being asked: "Should the law be changed to allow same-sex couples to marry?"
However, some supporters of same-sex marriage have said a national debate could allow for abusive rhetoric, reports the BBC.
Minogue has previously described Australia as "backward" when it comes to marriage equality, saying "the Earth didn't cave in" when it was allowed in other countries and that "love is love".
The campaign for same-sex marriage has also received support from Australian actress Margot Robbie, who appeared on US sketch show Saturday Night Live over the weekend sporting a Say I Do Down Under T-shirt.
