Key Takeaways
Polygamous marriages, where individuals have multiple spouses simultaneously, is illegal in Australia. Unlike certain countries where such marriages are legally recognized and culturally integrated, Australia does not accept polygamous marriages under its legal framework. This discrepancy creates significant complexities for individuals from polygamous relationships seeking to obtain an Australia partner visa. This blog aims to clarify how Australian law addresses polygamous marriages and what this means for partner visa applications, however for further information or to ask specific questions, contact Australian Migration Lawyers today.
No. Polygamy is not legal in Australia. Under the Marriage Act 1961 (Cth), marriage is defined as a union between two people to the exclusion of all others, meaning a person cannot be legally married to more than one spouse at the same time in Australia. This applies uniformly across the country and is not affected by the cultural, religious, or personal beliefs of the individuals involved.
This means the answer is the same regardless of who is asking; whether the question is "can you have multiple wives in Australia," "can a Muslim have two wives in Australia," or about any other religious or cultural marriage practice. Australian civil marriage law does not distinguish between reasons for seeking a polygamous marriage; the legal position is identical in every case: only one legally recognised marriage can exist at a time under Australian law.

Polygamous marriage refers to a marital arrangement where an individual has more than one spouse simultaneously. This type of marriage can be categorised into several forms, with the most common being polygyny and polyandry:
Polygamous marriages may be legally recognized and culturally integrated in several countries, each with its own set of rules and practices:
Under Australian law, marriage is recognised as a union between two consenting adults to the exclusion of all others. This strict definition prohibits polygamous marriages, and entering into a second marriage while still legally married to someone else constitutes bigamy. Bigamy is classified as a criminal offence under Australian law, carrying a maximum penalty of up to five years imprisonment. This provision ensures that multiple marriages and multiple partners are not legally acknowledged in Australia.

Exceptions to a bigamy charge exist, such as when an individual reasonably believes their spouse has passed away, with a presumption of death after seven years of absence. Additionally, renewing wedding vows with the same spouse or performing a ceremonial reaffirmation is not considered bigamous.
To further prevent polygamous unions, the law requires marriage notices and declarations of conjugal status before a marriage ceremony takes place, and penalties apply to those providing false information or celebrants who officiate marriages despite legal impediments.
While some overseas marriages, including overseas polygamous marriages, may be legally valid in their countries of origin, such relationships are not recognised in Australia. Australian law, including the Family Law Act, mandates that all marriages and de facto relationships adhere to a monogamous definition. This exclusion poses significant challenges for individuals from polygamous backgrounds seeking partner visas or legal status in Australia.
This principle also extends to how the Migration Act 1958 and Migration Regulations define a "spouse" and a "de facto partner" for visa purposes. Both definitions require an exclusive relationship; a person cannot be recognised as the "spouse" or "de facto partner" of more than one person at the same time under Australian migration law, mirroring the position under the Marriage Act.
Understanding these distinctions is crucial for individuals from polygamous backgrounds navigating the Australian immigration system, something that an Australian Migration Lawyer can easily assist with.
To be eligible for a partner visa in Australia, applicants must meet certain criteria, with one of the most important being the commitment to a monogamous relationship. Below are the key eligibility requirements:
This is the same for subclass 820/801, subclass 309/100, and subclass 300 visas,
This "exclusion of all others" requirement also means that, in practice, a sponsor can generally only sponsor one partner visa applicant as their spouse or de facto partner at any given time. A person who has previously sponsored a partner visa applicant may also face additional restrictions on sponsoring a further partner visa applicant, separate from the polygamy issue, under the Migration Regulations' sponsorship limitation provisions.
Monogamous Relationship Requirement
A monogamous relationship is essential for partner visa eligibility. The Department of Home Affairs requires both parties to commit to a shared life that excludes all others. Consequently, polygamous relationships, where one person has multiple spouses, do not satisfy the criteria for a partner visa. Furthermore, polygamous marriages are not legally recognized in Australia.
This applies equally to de facto relationships. If a person is in an ongoing de facto relationship with more than one partner at the same time, this would not meet the "exclusion of all others" requirement for a partner visa, in the same way that a polygamous marriage would not.
Individuals from polygamous marriages may encounter several challenges when applying for visas under Australian immigration law, including recognition issues, documentation difficulties and extended processing times.
Here are some practical steps to help navigate the challenges of applying for visas under Australian immigration law:
It is also worth noting that family violence provisions under the partner visa program, which allow a visa to proceed in certain circumstances even if a relationship has broken down due to family violence, operate separately from the polygamy issue. If family violence is a factor in a polygamous relationship breakdown, this should be raised directly with a migration lawyer, as it may affect the available options.
For individuals in polygamous relationships who wish to migrate to Australia, navigating the visa application process can be challenging due to the legal requirement for monogamous relationships. However, there are potential legal pathways and alternatives to consider:

Importance of Transparency and Honesty: It is critical to be completely transparent and honest throughout the visa application process. Any attempt to conceal or misrepresent the facts, such as the existence of a polygamous marriage, can lead to serious consequences, including visa refusal or future restrictions on applying for visas. Providing full disclosure about past or present relationships—whether polygamous or not—ensures that the Department of Home Affairs can accurately assess the situation. This also enhances the credibility of the application and shows good faith, which is crucial when dealing with complex legal matters.
