Polyamorous Relationships and the Law in Australia

Polyamory and Australian Family Law

The traditional view of romantic and sexual relationships has changed significantly, embracing diverse expressions of love and commitment. One such expression is polyamory, where individuals form relationships with multiple partners with the knowledge and consent of everyone involved. While polyamory may seem unconventional, the Family Law Act 1975 (Cth) can apply to non-monogamous de facto relationships if certain criteria are met.

Non-monogamous relationships, including throuples, are becoming more visible in society. A throuple is a committed relationship involving three people, offering an alternative to traditional monogamy. As ethical non-monogamy gains recognition, it is important to understand how Australian family law interacts with these dynamics. With the right guidance, navigating these issues becomes easier.


What is a De Facto Relationship?

Australian law recognises a de facto relationship when two people live together on a genuine domestic basis without being legally married or related by family. Under section 4AA of the Act, couples who have lived together for at least two years usually meet the threshold. However, couples who live together for less than two years or on a less than full-time basis may still qualify if other factors support the existence of the relationship.


Polyamory and the Family Law Act

Polyamorous relationships can fall under the Family Law Act if two of the people are married or if they satisfy the requirements of a de facto relationship. The Act does not limit the number of partners a person may have, other than in cases of marriage, prohibited relationships, or age restrictions.


Legal Considerations for Polyamorous Relationships

Determining whether a polyamorous relationship qualifies as a de facto relationship often requires close examination. Courts assess many factors, including:

  • the existence of a sexual relationship,

  • financial independence or interdependence,

  • the public aspects of the relationship, and

  • the care and support of children.

Judges use these considerations to decide if someone is in one or more de facto relationships and/or married at the same time.

In addition, the law sometimes treats ongoing affairs or mistress relationships (and their equivalents) as relevant if they represent substantial, long-term relationships.


Recognising and Protecting Polyamorous Relationships in Australia

In 2009, lawmakers amended the Family Law Act 1975 (Cth) by adding sections 4AA(5)(a)-(b). These provisions gave the Court broader powers to recognise de facto relationships between people of any sex, whether or not they were also married or in another de facto relationship.

Although the statute provides clear authority, defining a de facto relationship outside traditional structures can still be challenging. Each case depends on its unique facts, and courts weigh a wide range of considerations. Case law highlights just how complex these determinations can become, especially when de facto relationships overlap with marriages or other partnerships.


Protecting Your Assets

Because of these complexities, you may want to clearly define your relationship arrangements and consider a binding financial agreement to safeguard your assets. For people in polyamorous relationships, such agreements can be especially valuable, since multiple partners might otherwise have legal claims.
