My partners and I are polyamorous: we all have multiple serious dating relationships, with the knowledge and approval of all parties. One of my partners is an Australian citizen living in the state of Victoria. All of her partners are foreigners living overseas. Currently, no one is married to anyone or in any relationship that would be recognised as de facto under Victorian law.
My partner's fiance wants to move to Australia and marry my partner. He's planning to apply for a prospective marriage visa, followed by a partner visa once they are married.
The partner migration booklet lists "a mutual commitment to a shared life as husband and wife to the exclusion of all others" as a visa requirement for married couples. (For de facto couples it's "a mutual commitment to a shared life to the exclusion of all others".)
What is needed to meet this requirement?
Of course they can't marry any other people, but that's already in marriage law. Do my partner and I have to break up, or would lesser restrictions (e.g. remaining long-distance, not sharing money, not going out as a couple) be enough?
Conversely, if we break up, we would like to stay friends, which implies calling each other often and visiting each other. It seems difficult to prove that the calls and visits are purely friendly and we are not simply hiding a continuing relationship. Would these actions make it impossible for my partner and her fiance to prove that they are now exclusive?
Is there any way to find a migration agent with experience on this problem?
