Child custody in Australia refers to the legal responsibility and decision-making authority that parents hold for their child after separation or divorce.
Under the Family Law Act 1975 (Cth), this concept is formally known as “parental responsibility” and determines both who the child lives with and who makes major decisions about their welfare, education, health, and upbringing.
In other words, child custody defines how parenting duties are divided after a relationship ends — ensuring that every decision prioritises the best interests of the child, as required by Australian family law.
Legally, child custody in Australia refers to the rights and responsibilities that determine how a child is cared for and who makes major decisions about their life after a separation or divorce.
The term “custody” is no longer used in Australian legislation — it has been replaced by “parental responsibility” under the Family Law Act 1975 (Cth).
This means that instead of deciding “who gets custody,” the law focuses on who holds decision-making authority (known as legal custody) and where the child lives or spends time (known as physical custody).
Both forms are assessed by the Federal Circuit and Family Court of Australia (FCFCOA) in line with the child’s best interests, as required under section 60CA of the Act.
In summary, child custody defines not ownership, but legal accountability — ensuring that each parent’s role supports the child’s welfare, safety, and development under Australian family law.
Australian courts and family lawyers recognise several key custody structures:
Each model is assessed under the guiding principles of safety, emotional security, and meaningful relationships with both parents where possible.

Child custody in Australia is determined by the Federal Circuit and Family Court of Australia (FCFCOA) according to the principles set out in the Family Law Act 1975 (Cth).
When parents cannot agree through Family Dispute Resolution (FDR), the Court makes a decision based on what is in the best interests of the child, as outlined under section 60CC of the Act.
To reach a determination, the Court considers a range of legal and factual factors, including:
Ultimately, the Court aims to make an order that provides a safe, supportive, and consistent environment for the child — balancing both parents’ roles while prioritising the child’s long-term welfare and development.
The distinction between legal custody and physical custody is fundamental:
A parent may share legal custody yet have limited physical custody if the child resides mainly with the other parent. Understanding this distinction is crucial when preparing consent orders or formal parenting plans with assistance from a find a family lawyer experienced in custody law.
Unmarried or de facto parents have identical legal obligations once paternity is established. Where both names appear on the birth certificate, each parent automatically holds equal parental responsibility.
However, disputes regarding time-sharing or major decisions may still arise. In such cases, parties must generally attempt FDR before filing proceedings. If unresolved, the FCFCOA can issue parenting orders setting out each parent’s rights, duties, and communication protocols.

A parent with primary custody or residence carries significant rights and duties, including:
These rights operate within the principle of shared parental responsibility unless the Court orders otherwise.
Under Australian family law, the best interests of the child form the central test for every custody and parenting decision made by the Court.
Section 60CC of the Family Law Act 1975 (Cth) outlines the legal criteria that determine what qualifies as being in a child’s best interests.
The Court gives primary consideration to two key factors:
In addition, secondary considerations help the Court assess the child’s overall wellbeing, such as:
Ultimately, the Court balances these factors to ensure that any custody order promotes the child’s safety, stability, and long-term emotional development — not the convenience or preference of either parent.
Yes. Custody or parenting orders may be varied if a material change in circumstances arises — for example, relocation, altered work commitments, or new risks to the child’s welfare.
Applicants must present credible evidence that the change serves the child’s best interests. Courts generally require parties to attempt mediation before returning to litigation, except in urgent or high-risk cases.

The Federal Circuit and Family Court of Australia is responsible for:
The Court’s role extends beyond dispute resolution — it safeguards children’s rights through consistent application of the Family Law Act 1975 (Cth) and procedural fairness principles.
Child custody is complex and emotionally charged. The following questions address common legal issues Australian parents face.
Child custody governs both living arrangements and parental decision-making. Legally, it falls under the concept of “parental responsibility.”
Custody may be sole, joint, equal-time, or primary residence with contact rights. The arrangement must satisfy the child’s best-interest standard.
The Court examines factors under section 60CC of the Family Law Act 1975 (Cth), focusing on the child’s safety, welfare, and need for stable relationships.
Yes. Once parentage is proven, unmarried parents share the same legal rights as married couples and can formalise arrangements through parenting orders.
Orders may be changed where circumstances significantly evolve. The applicant must demonstrate that variation benefits the child’s welfare.
Child custody law in Australia operates on a single foundational principle: the welfare of the child outweighs all other considerations. Every decision — from residence to parental authority — must comply with the Family Law Act 1975 (Cth) and be supported by clear evidence.
If navigating a parenting dispute, early legal advice is essential. The right representation can help structure enforceable agreements, reduce conflict, and protect the child’s best interests.
