The separation is happening. The tension is real, and so are the possibly, almost definitely passive-aggressive text messages. And now the hardest question of the lot is sitting in front of you, who do the kids live with, and when?
Here is the short answer. There is no single “right” arrangement, and there is no automatic 50/50 in Australia. A court does not start from equal time or equal say. It starts, and finishes, with one thing, which is the best interests of the child, or children, involved. This page walks you through the arrangements that actually work, which one tends to suit which situation, and how to lock an agreement in so it holds.
I’m the principal at Justice Family Lawyers and one of the firm’s child custody lawyers. I like to break down how the law actually works so you understand your position, not just the theory. Let me walk you through it, starting with a word that trips almost everyone up.
“Custody” is not really a legal word here
You will hear “custody” everywhere, but Australian family law stopped using it decades ago. Getting the words right matters, because the wrong words set the wrong expectations.
There are two ideas that do the work. The first is parental responsibility, which is who makes the big long-term decisions for a child, things like schooling, serious health matters, and religion. The second is who the child lives with and who they spend time with. That is the day-to-day arrangement.
Here is the catch most people miss. Sharing the big decisions does not mean sharing the time equally. You can have a real say in your child’s schooling and still not have the child living with you half the week. They are two separate questions. The government’s own plain-English guide at Family Relationships Online makes the same point.
What changed on 6 May 2024
This is the part a lot of pages still get wrong. The law changed, and plenty of older articles describe a system that no longer exists.
On 6 May 2024 the presumption of equal shared parental responsibility was removed, and the best-interests factors were rewritten. So there is no longer a starting assumption that decision-making is shared, and no starting assumption of equal or “substantial and significant” time. The court does not begin from a default and adjust. It begins from the child.
What a court actually weighs now
So what does a court look at? Not who is the “better parent”. It weighs a shorter, clearer set of things.
Safety comes first, the safety of the child and of each person caring for them. Then any views the child has expressed. Then the child’s developmental, psychological, emotional and cultural needs, and each parent’s capacity to meet them. And the benefit to the child of a relationship with both parents, where that relationship is safe.
Read that list again and notice the order. Safety is not one factor among many any more. It is the first thing on the page.
These best-interests factors sit in s 60CC of the Family Law Act 1975 (Cth).
The most common arrangements (and when each actually works)
Once you know the test, the schedules make more sense. Here are the ones we see most often, and a straight word on when each one holds up.
- Alternate weekends. The child lives mainly with one parent and spends alternate weekends with the other. Works when one home is the settled base and the other parent wants regular, reliable time without disrupting the school week.
- Week about (alternate weeks). One week with each parent. Works when parents live close, communicate reasonably, and the child is old enough to cope with a longer stretch away from each of them.
- Alternating weeks with a mid-week visit. Week about, softened by a dinner or overnight in the middle. Works when a full week feels too long between contact for a younger child.
- School-holiday split. The term-time base stays put and holidays are shared or alternated. Works well as the backbone for a parent who travels for work or lives further away.
- Two-two-three. Two days with one parent, two with the other, then three, rotating over a fortnight. Works when parents are close by and can handle frequent changeovers without friction.
- Nesting. The children stay in one home and the parents rotate in and out. Works as a short-term bridge while things settle, and rarely as a long-term answer, because it asks a lot of both parents.
Which arrangement suits which age
Age shapes what tends to work, but read this as a set of starting points, not a court rulebook.
| Child’s stage | What often works as a starting point | Why |
|---|---|---|
| Babies and toddlers | Shorter, more frequent time with each parent, homes kept close | Very young children track time through routine, not a calendar, so long gaps are hard |
| Preschoolers | Short blocks that can stretch to the occasional overnight | Growing memory and security make a night away more manageable |
| Primary school | Longer, more predictable blocks, and a week-about split can start to work | School and activities reward a steady, repeating routine |
| Teenagers | More flexibility, with real weight given to what they want | Their own schedule, friendships and views start to drive the arrangement |
These are developmental guides, not rules a court must follow. A court always comes back to the child’s best interests and the family’s real logistics, so treat the bands as a place to start the conversation, not a formula.
What a 50/50 arrangement really looks like
A lot of parents assume 50/50 is the default, or a right. It is neither. And in practice, it is far less common than people think.
According to the Australian Institute of Family Studies, only 3% of all cases result in children living primarily with their fathers after separation. Around 79% of kids mostly live with their mothers and just 7% of separated parents have a true 50-50 shared care arrangement.
That is not a comment on who deserves what. It is what the numbers actually show. A true split only works when a few things line up.
Think about the things that need to fall into place in order for a 50-50 arrangement to work. The parents need to live close to each other. They need to be able to communicate reasonably well. And the child needs to be able to switch between homes. And let’s be honest, some parents can barely communicate about school shoes without turning into an argument, let alone a whole 50-50 arrangement.
If you live twenty minutes apart, you can be civil about the handover, and your child copes well with two homes, 50/50 can be a good fit. If not, forcing it usually hurts the child more than it helps.
A real outcome
Theory only goes so far, so let me tell you about one of our own matters. A client of ours, we will call him Nathan, worked fly-in fly-out on a two-weeks-on, two-weeks-off roster. The other parent argued the roster was too unstable for him to have regular care, and on paper it looked that way.
Nathan nearly gave up, but instead he worked with us to build a practical plan that would be feasible for him and the kids. He started to align his off weeks with the school holidays. He built a system of consistent communication whilst he was away, and we managed to get him joint parental responsibility, which meant that he felt like he was still involved in the decision-making process of the kids.
The lesson is simple. A workable arrangement is built around the real logistics of your life, not around a 50/50 ideal that looks fair on a page. Get the shape right first, then make it stick.
Parenting plan, consent order or parenting order?
This is where a lot of people get caught out. You agree on an arrangement, you write something down, and you assume it is binding. Often it is not. Here is how the three options actually differ.
| Option | What it is | Legally binding? | How you get it |
|---|---|---|---|
| Parenting plan | A written agreement you both sign and date | No. It is a written handshake deal | Write it down, both sign it |
| Consent orders | The same kind of agreement, approved by a court | Yes | Agree, then file for the court’s approval |
| Parenting order | A decision the court makes when you cannot agree | Yes | Apply to the court |
A parenting plan is flexible and easy, and it counts for something if a dispute ever lands in court. But it cannot be enforced. Consent orders take the exact same terms you have agreed and make them court-approved and binding. That is what I like to call the holy grail: agreement plus enforceability, without a fight. A parenting order is what a court makes for you if you cannot get there yourselves.
How to apply for consent orders is set out by the Federal Circuit and Family Court of Australia.
How to make it official (the pathway)
If you want an arrangement that holds, the order of steps matters.
- Try family dispute resolution first. A trained mediator helps you work towards agreement, and in most cases this step comes before court, not instead of it.
- If it does not resolve, you are issued a section 60I certificate. That is the document that lets you file in court, so you will actually meet this one.
- If you do agree, lodge consent orders and turn the agreement into something binding.
- If you cannot agree, you apply for a parenting order and the family court process decides it for you.
There are limited exceptions to the dispute-resolution step, mainly family violence and genuine urgency, where you can go straight to court.
Wherever you are in Australia, this is the same pathway. The Federal Circuit and Family Court of Australia handles parenting matters nationally, so the process does not change from state to state.
The section 60I certificate is explained by the Attorney-General’s Department.
When safety is the concern
Sometimes the honest answer is that shared time is not safe, and that has to come first.
Safety is now the first thing a court considers. Where there is a real risk of family violence, abuse or neglect, shared care or unsupervised time may not be appropriate, and a court can order supervised time, reduced contact, or other protective measures. The point is not to punish a parent. It is to keep the child safe while their relationship with each parent is worked out.
If safety is your worry, say so clearly and early, and get advice on how to raise it the right way.
Safety as the first consideration is part of the 6 May 2024 changes to the best-interests factors.
What if the other parent won’t follow the arrangement?
Here is why the paperwork matters. A parenting plan cannot be enforced. Consent orders and parenting orders can.
A breach is when a parent does not do what an order requires, whether that is returning the child on time, sticking to the holiday schedule, or handing over for the other parent’s time. When an order is in place, a court can step in and enforce it. I have seen how quickly a friendly, informal deal can fall apart.
We had a client at our office, let’s call her Anna for anonymous sakes, and she had a parenting plan in place with her ex. Things were going well until he got into a new relationship and suddenly the pickup times were all off, holiday schedules were completely ignored and the agreement wasn’t being honoured. We then got involved and helped her turn that agreement into consent orders.
The plan on its own gave Anna nothing to enforce. The consent orders did.
The court’s compliance and enforcement process for parenting orders explains what happens when an order is breached.
Where to from here
There is no perfect arrangement, only the one that fits your child and your real life, and holds up when things change. Work out the shape that suits your situation, then get it in writing in a form that is actually binding.

Frequently Asked Questions
What are the most common child custody arrangements Australia parents actually use?
The most common child custody arrangements Australia parents use are alternate weekends, week-about (alternate weeks), alternating weeks with a mid-week visit, a school-holiday split, and the two-two-three rotation. Which one works depends on how close the parents live, how well they communicate, and the child’s age. There is no single default arrangement.
Is there a default 50/50 custody arrangement in Australia?
No. Equal time is not a default and not a right. A true 50/50 split only works when parents live close, can communicate reasonably, and the child copes well moving between two homes. A court decides on the child’s best interests, not on a fixed formula.
Is "custody" a legal term in Australia?
Not really. Australian family law talks about parental responsibility (who makes the big long-term decisions) and who the child lives with and spends time with. Sharing decision-making does not mean sharing time equally, which is why the two ideas are kept separate.
What custody arrangement is best for a young child?
For babies and toddlers, shorter and more frequent time with each parent usually works better than long stretches apart, because very young children rely on routine. These are starting points only. A court comes back to the child’s best interests and the family’s practical circumstances.
What changed in Australian child custody law in 2024?
On 6 May 2024 the presumption of equal shared parental responsibility was removed and the best-interests factors were rewritten. There is no longer any starting assumption of shared decision-making or equal time. The court works only from what is in the child’s best interests, with safety as the first consideration.
How do I make a custody arrangement legally binding?
A parenting plan you both sign is not enforceable. To make an arrangement binding, you file for consent orders, which take your agreed terms and have a court approve them. If you cannot agree, you apply for a parenting order and the court decides.
What happens if the other parent won't follow the arrangement?
If you only have a parenting plan, there is nothing to enforce. If you have consent orders or a parenting order, a breach can be taken back to court, which can enforce the order. This is the main reason to turn an informal agreement into orders.
