Polygamous Marriages and the Partner Visa
Only one spouse can be sponsored for an Australian partner visa, because the Migration Act 1958 (Cth) requires a commitment to a shared life as a married couple to the exclusion of all others, even where a polygamous marriage was valid where it took place.
Polygamy is not lawful in Australia: going through a marriage ceremony while already married is bigamy under s 94 of the Marriage Act 1961 (Cth), with a maximum penalty of 5 years' imprisonment, and an overseas marriage is not recognised where either party was already married to someone else (s 88D(2)(a)).
| Situation | Can this spouse be sponsored? | Why | Provision |
|---|---|---|---|
| First spouse, and any later marriages have ended | Yes, if the rest of the test is met | The first marriage can be recognised, and the couple can now share a life to the exclusion of all others | Migration Act s 5F; Marriage Act s 88D(1) |
| First spouse, while a later spouse relationship continues | No, while it continues | The exclusivity limb is not met | Migration Act s 5F(2)(b) |
| A second or later spouse | No | The marriage is not recognised, because a party was already married when it was made | Marriage Act s 88D(2)(a) |
| A de facto partner, while the sponsor's marriage to someone else continues as a relationship | No, while it continues | The de facto definition also requires a shared life to the exclusion of all others | Migration Act s 5CB(2)(a) |
| More than one de facto partner (polyamory) | No | The same exclusivity words | Migration Act s 5CB(2)(a) |
Which of these rows describes your family is a question about your own application. Advice on it is immigration assistance as defined in s 276 of the Migration Act 1958 (Cth), which under s 280 only a registered migration agent or an Australian legal practitioner may give.
Can you sponsor more than one spouse for a partner visa?
No. Two provisions close it off together. Section 5F(2)(b) of the Migration Act 1958 (Cth) makes two people spouses only if they have "a mutual commitment to a shared life as a married couple to the exclusion of all others". And s 88D(2)(a) of the Marriage Act 1961 (Cth) refuses recognition to a marriage made while either party was already in a marriage recognised in Australia. The married-couple route is explained on spouse visa Australia.
Can a polygamous marriage support a partner visa?
No. Australia does not allow polygamy: a marriage in Australia is void if either party is already married (s 23B(1)(a)), and going through a marriage ceremony while married is bigamy (s 94). Section 6 of the Family Law Act 1975 (Cth) treats a polygamous union entered outside Australia as a marriage for proceedings under that Act, such as property or parenting matters. That is a family law rule. It does not make a polygamous marriage valid for a partner visa.
Is a polygamous marriage made overseas recognised for a partner visa?
Only the first marriage, and only in part:
- The first marriage can be recognised under s 88D(1) if it was valid where it was made. The first spouse still has to meet s 5F, including the exclusivity limb, which is not met while another spouse relationship continues.
- A later marriage made while the first continued is not recognised (s 88D(2)(a)). Because the test looks at the time of the marriage, ending the first marriage later does not validate it.
The general recognition rules are on overseas, online and proxy marriages.
Does the same partner visa rule apply to de facto and polyamorous relationships?
Yes. Section 5CB(2)(a) of the Migration Act 1958 (Cth) requires de facto partners to have "a mutual commitment to a shared life to the exclusion of all others". A sponsor cannot sponsor two de facto partners at once, and cannot sponsor a de facto partner while a spouse relationship with someone else continues.
Questions about polygamous marriages and the partner visa
Can a man marry two wives legally in Australia?
No. Nobody who is married can lawfully marry again in Australia until the first marriage has ended by divorce, death or annulment.
Can the children of a polygamous marriage migrate?
Children apply under different visas, which this guide does not cover.
Does ending the other marriage change the answer?
For the first spouse, it can: once the other relationships have ended, the exclusivity limb can be met. For a later spouse, the marriage stays unrecognised, but once the earlier marriage has ended the couple could marry again, or apply as de facto partners if they meet those rules.
What the partner visa sponsor must meet
- The partner visa sponsor requirements set out who can sponsor and the limit of two partners in a lifetime under reg 1.20J.
- The married-couple route is explained on the spouse visa page linked above.
A partner visa built on a marriage Australia does not recognise, or on a relationship that fails the exclusivity limb, is refused on the first criterion. An application prepared by a registered migration agent or an Australian legal practitioner is more likely to succeed, because they establish which marriage is recognised and what has to end first, before anything is lodged. No adviser can promise a grant.
Questions people ask
Can you sponsor more than one spouse for a partner visa?
No. Section 5F(2)(b) of the Migration Act 1958 (Cth) requires the couple to have a mutual commitment to a shared life as a married couple to the exclusion of all others, and s 88D(2)(a) of the Marriage Act 1961 (Cth) stops Australia recognising a marriage made while either party was already married.
Is polygamy legal in Australia?
No. Under s 94 of the Marriage Act 1961 (Cth), a married person who goes through a form or ceremony of marriage with anyone commits bigamy, with a maximum penalty of 5 years' imprisonment. A marriage in Australia is void if either party is already married to someone else.
Can a man marry two wives legally in Australia?
No. A person who is married cannot lawfully marry again in Australia until the first marriage has ended, and a second marriage made overseas while the first continued is not recognised in Australia.
Does the same rule apply to de facto partners?
Yes. Section 5CB of the Migration Act 1958 (Cth) requires de facto partners to have a mutual commitment to a shared life to the exclusion of all others, so a sponsor cannot sponsor two de facto partners, or a de facto partner while another spouse relationship continues.
