As Sydney comes alive for the 48th Sydney Gay and Lesbian Mardi Gras – running from 13 February to 1 March 2026, with the iconic Parade lighting up Oxford Street on Saturday 28 February – it is a powerful reminder of how far Australia has come in recognising and protecting LGBTIQA+ individuals and families.
This year’s theme, ECSTATICA, celebrates joy as power and resistance. With over 12,000 marchers, 200-plus floats, and hundreds of thousands of spectators expected along the parade route, Mardi Gras remains one of the most significant celebrations of pride, diversity, and progress in the world.
At Sarah Bevan Family Lawyers, we have spent over two decades standing alongside LGBTIQA+ individuals and families as they navigate the unique legal challenges that can arise in relationships, family formation, and separation. Our principal, Sarah Bevan, was instrumental in achieving the passage of the landmark Equality Legislation Amendment (LGBTIQA+) Act 2024 in NSW – particularly through her involvement in the Parliamentary Enquiry relating to surrogacy law reform.
Whether you are celebrating love this Mardi Gras season or working through a difficult transition, this guide covers the key family law issues that LGBTIQA+ individuals and families in Australia should know about.

ToggleAustralian family law has made significant progress in recognising and protecting the rights of LGBTIQA+ individuals and families. The Family Law Act 1975 (Cth), combined with state legislation, governs most matters relating to relationships, property, parenting, and family formation – and since the passage of marriage equality in December 2017, same-sex couples are afforded identical legal protections to heterosexual couples in all aspects of family law.
For a comprehensive overview of how these laws apply to LGBTIQA+ families, visit our dedicated LGBTIQA+ and Family Law page.
Understanding where the law stands today is easier when you appreciate the milestones that got us here:
Since December 2017, same-sex couples have been able to legally marry in Australia. The law applies equally regardless of the sex or gender of the parties. According to the Australian Bureau of Statistics, 4,746 same-gender or non-binary marriages were registered in Australia in 2024 (a 4.1% increase on the prior year) representing approximately 3.9% of all marriages.
If you were married overseas in a same-sex ceremony before 2017, your marriage
Not every couple chooses to marry, and the law recognises this. Since 2008, same-sex de facto couples in Australia have essentially the same rights as married couples under the Family Law Act 1975 in relation to property settlements, spousal maintenance, and parenting. A de facto relationship is generally established where two people live together on a genuine domestic basis and are not legally married.
The recognition of de facto relationships means that if your relationship ends, you can apply for property division and parenting orders through the Federal Circuit and Family Court – just as a married couple would.
The question of whether marriages involving a transgender person are valid has been addressed by both legislation and case law. In Australia, a marriage is valid regardless of whether one or both parties have transitioned gender during the marriage. For more on this topic, read our article on whether marriages involving a transgender person are valid.
The Equality Legislation Amendment (LGBTIQA+) Act 2024 further strengthened protections by allowing people in NSW to change their registered sex through an administrative process without requiring surgery, bringing NSW into line with every other Australian jurisdiction.
Relationship breakdown is difficult regardless of the nature of the relationship. For LGBTIQA+ couples, separation can sometimes carry additional complexities, including navigating legal parentage of children conceived through assisted reproduction, managing shared assets acquired during a period when the law did not fully recognise same-sex relationships, and dealing with family or community dynamics that may be complicated by sexual orientation or gender identity.
If you are going through a separation, our experienced family law team is here to provide compassionate, specialist advice tailored to your circumstances.
The divorce process for same-sex couples is identical to that for heterosexual couples. You must:
ABS data shows that in 2024, approximately 2.9% of all divorces granted in Australia were for same-sex marriages. As same-sex marriage has only been available since late 2017, these numbers are still emerging – but the process and rights are exactly the same.
For more information, read our guide on same-sex divorce in Australia.
When an LGBTIQA+ relationship ends, whether through divorce or the breakdown of a de facto relationship, both parties have the right to seek a just and equitable division of property. The Family Court considers the same factors for all couples:
Property division can be formalised through consent orders (if both parties agree) or through court determination if agreement cannot be reached. Couples may also consider entering into a Binding Financial Agreement (BFA) either before, during, or after a relationship, which is similar to a prenuptial agreement.
For specialist advice on property division, visit our same-sex property settlement page.
Separation and relationship changes often mean existing wills and powers of attorney need updating. Marriage automatically revokes a prior will in most Australian states, which means both entering into and ending a marriage should prompt a review of your estate planning. Our team can assist LGBTIQA+ individuals and couples with wills and powers of attorney as part of a comprehensive approach to protecting your interests.
Building and protecting rainbow families is one of the most rewarding (and legally complex) areas of LGBTIQA+ family law. Whether you are becoming a parent through surrogacy, donor conception, adoption, or co-parenting arrangements, understanding your legal rights is essential.
Surrogacy is one of the most common pathways to parenthood for LGBTIQA+ individuals and couples (particularly for gay men and single people). Sarah Bevan is one of Australia’s leading experts in both domestic and international surrogacy law, with landmark achievements including securing the first parentage orders in NSW allowing a same-sex couple to be named on a child’s birth certificate born through a surrogacy arrangement.
There are important legal distinctions to understand:
For specific surrogacy LGBTIQA+ advice, visit our same-sex surrogacy page, or read about the laws relating to international surrogacy for Australians.
Donor conception is another common pathway to parenthood for LGBTIQA+ families. Whether you are using a known or anonymous donor, having a legally sound agreement in place is critical to establishing parentage, protecting all parties, and avoiding disputes down the track.
Key legal points include:

Adoption by same-sex couples is legal in all Australian states and territories. In NSW, both single people and couples – regardless of sexual orientation – are eligible to apply to adopt. For LGBTIQA+ step-parents seeking to formalise their relationship with a partner’s child, step-parent adoption provides a legal pathway to full parental recognition.
Adoption remains a complex and often lengthy process in Australia. For specialist guidance, read our comprehensive guide on adoption in Australia.
When LGBTIQA+ relationships involving children break down, the Family Court makes parenting orders based on the best interests of the child – the same standard applied to all families. The court can make orders about:
It is important to note that a person does not need to be the biological or legal parent of a child to apply for parenting orders. The Family Court can make orders in favour of any person who is “concerned with the care, welfare or development of the child.” This is particularly relevant for LGBTIQA+ families where the family structure may not fit traditional legal definitions.
Family violence occurs in all communities, including LGBTIQA+ relationships. Research suggests that LGBTIQA+ individuals may experience domestic and family violence at rates comparable to or higher than the broader population, but may face additional barriers to seeking help – including fear of outing, lack of recognition by services, or minimisation of abuse in same-sex relationships.
If you are experiencing family violence, our team can assist with apprehended violence orders, safety planning, and ensuring that violence is appropriately considered in parenting and property proceedings. We also have information on coercive control in family law, which became a criminal offence in NSW from 1 July 2024.
The passage of this Act in October 2024 represented the most significant package of LGBTIQA+ law reform in NSW history. Our principal, Sarah Bevan, played a pivotal role in the reform process, particularly through her expert contributions to the Parliamentary Enquiry on surrogacy law — drawing on her decades of experience as one of Australia’s foremost surrogacy and fertility law specialists.
Key changes introduced by the Act include:

Understanding the size and diversity of Australia’s LGBTIQA+ community helps illustrate why inclusive family law matters.
Community size: In December 2024, the Australian Bureau of Statistics released its first-ever estimates of Australia’s LGBTI+ population. The ABS found that approximately 4.5% of Australians aged 16 and over – more than 900,000 people – identify as LGBTI+. Among younger Australians aged 16 to 24, that figure is closer to 10%.
Same-sex marriages: Since marriage equality became law in December 2017, tens of thousands of same-sex couples have married in Australia. In 2024 alone, 4,746 same-gender or non-binary marriages were registered (a 4.1% increase on 2023).
Same-sex families with children: According to Census data, the number of children living in same-sex families has grown significantly (from 3,400 in 2001 to more than 10,500 by 2016). The 2026 Census, which will for the first time include questions on gender and sexual orientation for people aged 16 and over, is expected to provide a much more detailed picture.
Mardi Gras by the numbers: The Sydney Gay and Lesbian Mardi Gras began on 24 June 1978 when around 1,000 people gathered at Taylor Square for what was intended as a peaceful street celebration. Police violence and the arrest of 53 participants that night sparked a movement. Today, the Mardi Gras Parade attracts over 12,000 marchers, more than 200 floats, and an estimated 300,000 or more spectators – making it one of the largest LGBTIQA+ events on earth.
Language in this area is evolving, and respectful, inclusive terminology matters.
LGBTIQA+ stands for Lesbian, Gay, Bisexual, Transgender, Intersex, Queer/Questioning, Asexual, and other diverse identities (represented by the “+”). It is the most broadly inclusive term and is used in Australian legislation, including the Equality Legislation Amendment (LGBTIQA+) Act 2024.
Same-sex is a commonly used legal and statistical term, particularly in the context of marriage and divorce data. The ABS has progressively shifted from “same-sex” to “same-gender” in its reporting since 2022 to better reflect the distinction between sex and gender, and to include non-binary individuals.
Gay and lesbian remain widely used and understood terms, but they do not capture the full diversity of the community – including bisexual, transgender, intersex, non-binary, and other identities.
In a legal context, we use the terminology that is most accurate for the situation. When discussing broader community rights and protections, we use LGBTIQA+ as it is the most inclusive term recognised in Australian law.
Sarah Bevan Family Lawyers has been at the forefront of LGBTIQA+ family law in Australia for over two decades. Here is what sets our firm apart:
Yes. Since the passage of marriage equality in December 2017, all legal same-sex marriages – including those performed overseas – are recognised in Australia. You can apply for divorce through the Federal Circuit and Family Court provided you meet the standard eligibility criteria: at least 12 months’ separation, and that you or your spouse are an Australian citizen, permanent resident, or ordinarily resident in Australia for at least 12 months before filing.
The Family Court applies the same “best interests of the child” test to all families, regardless of the parents’ sexual orientation or gender identity. The court considers factors such as the benefit of the child having a meaningful relationship with both parents, the need to protect the child from harm, and the views of the child (depending on their age and maturity). A person does not need to be the biological parent to be recognised as a parent or to apply for parenting orders.
Surrogacy and donor arrangements involve a complex intersection of state and federal law. Our firm can assist with drafting and advising on surrogacy agreements, sperm donor agreements, and egg donor agreements, as well as applying for parentage orders after birth. The recent changes under the Equality Legislation Amendment (LGBTIQA+) Act 2024 have expanded the availability of parentage orders for families formed through overseas commercial surrogacy.
Same-sex de facto couples have essentially the same rights as married couples under the Family Law Act 1975 in relation to property settlement, spousal maintenance, and parenting orders. You can apply to the Federal Circuit and Family Court for a property settlement if you have been in a de facto relationship for at least two years, or in certain other circumstances (such as where there is a child of the relationship or where significant contributions have been made).
Yes. Same-sex couples can enter into a Binding Financial Agreement (BFA) — the Australian equivalent of a prenuptial agreement — before, during, or after a marriage or de facto relationship. BFAs set out how financial matters will be handled in the event of separation, and can provide certainty and protection for both parties. Each party must receive independent legal advice for a BFA to be binding.
Australian family law currently recognises marriages and de facto relationships (including same-sex relationships), but does not provide specific recognition for polyamorous or multi-party relationships. However, the Family Court has broad powers to make orders in the best interests of children, and property claims can arise between any two people who were in a de facto relationship. If you are in a non-traditional relationship structure and are concerned about your legal position, we recommend seeking specialist legal advice early.
As the 48th Sydney Gay and Lesbian Mardi Gras lights up our city, we celebrate the extraordinary progress that has been made – from a protest march of around 1,000 people on Oxford Street in 1978, to one of the world’s largest and most spectacular celebrations of LGBTIQA+ pride and visibility.
But legal rights and protections remain essential. Whether you are navigating separation, building a family through surrogacy or donor conception, protecting your assets, or planning for the future, having a family lawyer who understands the unique challenges facing LGBTIQA+ individuals and families makes a real difference.
