De Facto Partner Visa Australia: Rules, Cohabitation Requirements, and Exceptions

Australia's partner visa system recognises two types of relationships: legally married couples and de facto couples. For de facto applicants, there is an additional legal hurdle that married couples do not face — a mandatory cohabitation requirement that has ended many otherwise genuine applications before they even began. Understanding exactly how this requirement works, and when it can be legally bypassed, is essential before you decide when and how to apply.

The 12-Month Rule

Regulation 2.03A of the Migration Regulations 1994 requires that a de facto relationship must have existed for at least 12 months immediately before the date the partner visa application is lodged. This is a strict condition. It is not 12 months of knowing each other, 12 months of being in a romantic relationship, or 12 months of being exclusive. It is 12 months of being in a de facto relationship — which the Department of Home Affairs treats as requiring actual cohabitation and mutual commitment to a shared life.

If you fall short of this threshold by even a week, the application will be refused. The Department does not exercise discretion on the timeline itself — the criterion is a bright-line rule.

This is where many couples run into trouble. A common scenario: two people meet, begin a relationship, maintain separate residences for the first several months while seeing each other regularly, then move in together. If they apply for a partner visa six months after moving in, they typically do not have 12 months of de facto relationship history in the Department's view, even if the total relationship duration is over a year. The 12 months is counted from when the relationship reached the threshold of a genuine de facto partnership — which the Department ties closely to cohabitation.

What Counts as a De Facto Relationship

Under Section 5CB of the Migration Act 1958, a de facto relationship exists when two people are not legally married to each other, are not related by family, and have a mutual commitment to a shared life as a couple on a genuine domestic basis — living together or, if not living together, not separated on a permanent basis.

The key phrase is "genuine domestic basis." The Department does not require that you live under the same roof for every single day of the 12 months. Periods of temporary separation — for work, travel, or family obligations — can be accommodated if you can demonstrate that the de facto relationship continued through those periods via communication evidence, financial remittances, and continued integration of financial and household arrangements.

What the Department will not accept is a relationship that is primarily long-distance without a history of actual cohabitation. If you have been together for two years but have never lived together in the same country, you likely do not have a qualifying de facto relationship for visa purposes.

Applying Without Having Lived Together: The Relationship Registration Option

Here is the legal exception that changes the calculus entirely. Regulation 2.03A includes a waiver of the 12-month cohabitation requirement for couples who have formally registered their relationship with an Australian state or territory government authority.

Every Australian state and territory allows couples to register their de facto relationship officially — in NSW through the Registry of Births, Deaths and Marriages; similarly in Victoria, Queensland, South Australia, Western Australia, and the ACT. A registered relationship certificate from any of these authorities effectively substitutes for the 12-month cohabitation history, allowing a couple to lodge a partner visa application without satisfying the time requirement.

This is not a loophole. The registration process itself requires evidence that the relationship exists and that both parties genuinely consent to the registration. What it does is remove the temporal barrier while preserving the requirement to prove the relationship is genuine and continuing under the Four Pillars framework. You still need financial evidence, household evidence, social evidence, and commitment evidence — the registration simply means you can seek these assessments without first waiting 12 months.

For couples where religious or cultural traditions prohibit cohabitation before marriage — a common scenario among South Asian couples, for example — relationship registration is frequently the recommended pathway to avoid both waiting an extended period and compromising cultural or family expectations.

Partner Visa Without Living Together: Practical Strategies

Some couples genuinely cannot live together before applying — due to immigration status, geographic constraints, or cultural reasons. Beyond relationship registration, the key strategies are:

Demonstrating the de facto relationship through evidence other than cohabitation. If you have been in a genuine committed relationship with documented financial interdependence, regular communication, visits, and social integration — but lived separately for legitimate reasons — you can make the case that the de facto relationship predates the cohabitation. This requires a thorough explanation in your personal statements and strong corroborating evidence across all other pillars.

Considering the married couple pathway instead. If you are engaged and plan to marry, applying for a Prospective Marriage Visa (Subclass 300) to travel to Australia to marry may be a more direct route than trying to establish a de facto relationship from offshore. After marrying in Australia on the Subclass 300 visa, you transition into the onshore 820/801 system as a married couple, without the 12-month de facto cohabitation requirement.

Applying as a married couple. If the relationship has reached the point where marriage is the plan, marrying before lodgement and applying as a married couple removes the de facto cohabitation requirement entirely.

Evidence for De Facto Partner Visas

The evidentiary burden for de facto applications is arguably higher than for married couples, because the relationship lacks the legal anchor of a marriage certificate. Case officers need to be persuaded through documentary evidence that the relationship meets the statutory definition.

The strongest evidence for de facto cohabitation is a joint lease in both names, or a lease in one name with supporting documentation showing both partners actually live there — utility bills, official government correspondence, bank statements sent to the shared address. Bank statements showing shared expenses over the 12-month period, ideally from a joint account or through cross-transfers between individual accounts, are critical.

Communication evidence matters here too. A consistent, daily pattern of contact throughout the 12-month period — not just in the most recent months before lodgement — helps establish when the de facto relationship began and demonstrates continuity.

Same-Sex De Facto Relationships

Australia fully recognises same-sex de facto relationships under the partner visa framework. Following the legalisation of same-sex marriage in December 2017, same-sex couples have equal access to both the married and de facto pathways and are assessed under identical criteria. No additional evidence requirements apply specifically because of the nature of the relationship.

Navigating the de facto rules is one of the more technically complex parts of the partner visa application, particularly for couples who have lived apart, come from cultures where cohabitation before marriage is not practised, or are caught by the 12-month timing requirement. The Australia Partner Visa (820/801) Guide covers de facto relationship evidence strategies in detail, including how to use relationship registration, how to document a relationship that spans multiple countries, and how to address gaps in cohabitation evidence through the Four Pillars framework.
