There's no automatic rule that children go to one parent — the law starts and ends with what's best for the child.
When a relationship ends and children are involved, the hardest question usually comes first: where will the children live, and how much time will they spend with each parent? Australian family law doesn't start from either parent's rights. It starts and ends with one question — what is in the best interests of this child?
There is no automatic 50/50, and no rule that “mum always gets the kids.” Equal time is one possible outcome, not a starting assumption. What matters is the individual child's safety, needs and circumstances — not a formula applied to everyone.
Two different things often get confused. “Parental responsibility” is about who makes the big long-term decisions — school, serious health, religion. “Living arrangements” are about who the child lives with and spends time with day to day. You can share one without sharing the other.
What the court weighs. Safety comes first — protecting a child from harm and from exposure to family violence. After that: the benefit of a meaningful relationship with both parents where it is safe, the child's own views (given weight according to age and maturity), and the practical realities of each home.
You don't have to go to court. Most parents reach their own arrangement — either an informal parenting plan, or formal consent orders that a court can approve without a hearing. In most cases you are expected to attempt family dispute resolution (mediation) before applying to court, though there are exceptions, including where there is family violence or genuine urgency.
The arrangements that last are the ones built around the child rather than the conflict. If you're separating, get advice early, keep the focus on the children, and write down what is already working — it is far easier to formalise a routine that works than to rebuild one after a dispute.
