Co-parenting can refer to the shared responsibility of raising a child by both parents, even after separation or divorce. In the context of family law, co-parenting ensures that both parents continue to play an active role in their child’s life, despite the breakdown of their relationship. It prioritises the child’s best interests, ensuring that they receive care, guidance, and support from both parents.

An Example of Healthy Co-Parenting

Two parents, Sarah and Mark, who have recently separated but share care of their 8-year-old son, Liam. They both agree on a parenting plan that allows Liam to spend weekdays with Sarah, as she lives closer to his school, and weekends with Mark.  Both parents treat each other with respect and courtesy.

To ensure consistency, Sarah and Mark communicate regularly about Liam’s schoolwork, discipline issues, extra-curricular activities, and any health concerns. Even though they live in separate homes, they make decisions together about Liam’s education and healthcare as some examples, ensuring he has a stable and supportive environment. Both parents attend Liam’s school events and share the responsibility of transportation, without involving him in any disagreements they might have.

This approach allows Liam to benefit from the care and involvement of both parents while maintaining a sense of routine and security.  

Legal Considerations when it comes to Co-Parenting

In Australia, co-parenting comes with significant legal responsibilities. Under the Family Law Act 1975, if a parenting order is in place providing for joint decision-making about major long-term issues, then both parents must make certain important decisions about their child’s upbringing together. These decisions can include matters like education, healthcare, and religious upbringing. However, joint decision-making about major long-term issues does not necessarily mean equal time spent with the child, as this is determined by what is in the best interests of the child.

It can be useful for parents to formalise parenting arrangements, either through a Parenting Plan or applying for a Parenting Order, to avoid misunderstandings and ensure that everyone involved knows their responsibilities.

  •  A Parenting Plan is a written agreement between the parents, which can be flexible but is not legally enforceable. 
  • A Parenting Order by consent is made by the court with the agreement of both parents and is legally binding and enforceable. 

For families facing disputes or complex situations, seeking legal advice can be helpful. Daykin Family Law offers expert guidance to help parents reach fair, legally sound parenting arrangements that take into account the best interest of the child. With a focus on minimising conflict and prioritising the child’s well-being, Daykin Family Law ensures that families can navigate co-parenting with clarity and support.

Co-Parenting and Child Support

Financial responsibility is a crucial aspect of co-parenting, and both parents are expected to contribute to the costs of raising their child, even after separation. Child support is designed to help cover essential expenses such as schooling, healthcare, and daily living costs. The amount each parent contributes typically depends on factors such as income, the number of children, and the time spent with each parent.

It’s important to ensure that child support arrangements are appropriate and meet the child’s needs. For more details on how child support is calculated and what obligations co-parents may have, you can read our blog on How Much is Child Support in Australia?. Understanding these financial responsibilities helps create a stable environment for the child, ensuring their well-being is always prioritised.

Parents can also enter into private agreements regarding child support. Read more about this option.

Tools and Tips for Successful Co-Parenting

Maintain Open Communication

Clear, respectful, and regular communication is key to ensuring both parents stay informed about their child’s needs and activities. Use email, messaging apps, or scheduled calls to keep conversations focused and constructive.

Use Co-Parenting Apps

Several apps are designed to help manage co-parenting logistics, such as shared calendars, expense tracking, and communication. Apps like OurFamilyWizard and 2Houses can assist in organising schedules and keeping everything documented for smooth communication and understanding.

Create a Consistent Routine

Consistency is important for children, especially after a separation. Creating a structured routine for your child that is upheld in both households can lead to co-parenting success. This includes meal times, bedtimes, and school activities. Consistency reduces stress for the child and helps them adjust to the new family dynamics.

Set Boundaries

While co-parenting requires communication, it’s essential to set clear boundaries about each other’s personal lives. Respecting these boundaries ensures a more harmonious co-parenting relationship, allowing both parents to focus on their child’s needs.

Seek Mediation When Necessary

Disagreements are bound to happen, but when they become difficult to resolve, consider seeking mediation. Family mediation provides a neutral space where parents can address conflicts and come to mutually beneficial agreements.

When You Should Seek Legal Advice When Co-Parenting

While co-parenting can often be managed amicably, there are certain situations where seeking legal advice is necessary to ensure the best outcome for both parents and children.

Disagreements on Parenting Arrangements

If parents are unable to agree on where the child will live, how much time they will spend with each parent, or other key issues, legal advice can help resolve disputes. A family lawyer can guide you through dispute resolution processes such as mediation, or assist in drafting a Parenting Plan or applying for a Parenting Order.

Concerns About Child Safety

If there are concerns about your child’s safety due to family violence, neglect, or abuse, it’s crucial to urgently seek legal help immediately. Family lawyers can assist in applying for court orders to ensure the child’s protection, including urgent applications if needed.

Changes in Circumstances

If there has been a significant change in circumstances – such as relocation, changes in employment, or health concerns, that affects existing parenting arrangements, seeking legal advice can help you navigate the necessary adjustments or amendments that may need to be proposed or applied for in relation to court orders.

Breach of Parenting Orders

If the other parent is not following the agreed Parenting Plan or court-ordered arrangements, legal action can be necessary. A lawyer can help with enforcement of the existing orders, negotiate new terms, or take necessary legal action to ensure compliance in some circumstances.

Relocation or Travel Disputes

If one parent wishes to relocate or take the child overseas, and the other parent does not agree, legal advice should be sought. This ensures that any moves comply with family law.

What is Child Support?

Child support is a financial obligation paid by one parent to the other, aimed at contributing to the everyday living expenses of their children following separation or divorce. Its core purpose is to ensure that children maintain a standard of living that closely resembles what they might have enjoyed had their family remained intact. This system underscores the principle that both parents bear equal responsibility for their children’s expenses and financial security and generally leads to more positive outcomes for children who are in this situation through no fault of their own.

In Australia, child support is predominantly governed by the Child Support (Assessment) Act 1989, alongside the Family Law Act 1975 (Cth) in some cases. These pieces of legislation establish the rules for assessing, collecting, and transferring child support payments, ensuring that the process is transparent, and considers the financial capacity of each parent. The Department of Human Services (DHS), through its Child Support Program, administers these laws, providing a structured approach to help parents manage their child support arrangements efficiently and equitably.

How Is Child Support Calculated?

To determine the child support amount, the DHS uses a child support assessment formula that examines the situation of both parents. There are six different formulas used to calculate the child support amount, which can be difficult to understand – but that’s OK, we’re here to help! 

In most cases, the annual amount of child support will be calculated using Formula 1, the Basic Child Support Formula. This formula is used for single child support assessments where only the parents provide care for the children and neither parent has another child support assessment case.

How to Calculate Your Child Support

Let’s look at the steps to calculate child support. After outlining the initial steps, we go through an example with Bob and Mary and their child support costs for their 9-year-old daughter – jump to this if you want a more concrete explanation! If we use the Basic Child Support Formula as provided by the Australian Government’s Guides to Policy, child support is calculated as follows:

1. Identify the child support income for each parent

Start by determining the child support income for each parent. You calculate this by looking at a parent’s taxable income and subtracting the amount each parent would need to support themselves individually.

2. Calculate the combined child support incomes for a total child support income

Add both parent’s child support incomes together for a total.

3. Calculate each parent’s income percentage

Divide each parent’s child support income by the total child support income to get their income percentage.

4. Determine each parent’s percentage of care

This is the amount of time each parent spends caring for the child which influences the support calculation, with more significant care responsibilities potentially reducing the financial obligation.

  • Below regular care: 0% to 13% of the time is equal to 0 to 51 nights a year or 0 to less than 2 nights fortnightly.
  • Regular care: 14% to 34% of the time is equal to 52 to 127 nights a year or 2 to 4 nights a fortnight.
  • Shared care: 35% to 64% of the time is equal to 128 to 237 nights a year or 5 to 9 nights a fortnight.
  • Primary care: 65% to 86% of the time is equal to 238 to 313 nights a year or 10 to 12 nights a fortnight.
  • More than primary care: 87% to 100% of the time is equal to more than 313 nights a year.

5. Determine the cost percentage

Based on the care percentage, use the chart to identify the extent to which each parent contributes to the child’s costs through direct care.

0-13%0-511Less than regular care0%

66-86%238-31310-12Primary care76%
87-100%314-36513-14More than primary care100%

6. Calculate each parent’s child support percentage

This step involves subtracting the cost percentage from the income percentage for each parent,  to calculate the child support percentage. This determines who pays and who receives child support.

If the child support percentage is negative, this parent will receive child support.

If the child support percentage is positive, this parent will pay child support.

There may be different arrangements for different children, therefore there may be different support percentages for each child.

*Steps 7 and 8 use only the positive child support percentage.

7. Work out the cost of each child

Work out the cost of each child based on the parents’ total combined child support income and by using the charts below:

8. Calculate child support amount

Multiply the positive child support percentage by the cost of the child to determine the annual rate of child support that will be paid.

These steps are designed to ensure that child support payments are equitable and reflect the financial capabilities of each parent, the needs of the child, and the practicalities of the care arrangements.

Example

Now, let’s look at an example.

Bob and Mary are calculating their child support payments. Bob makes $99,841 per year, and Mary makes $59,841. Now let’s go through the formula step by step.

  1. Identify the child support income for each parent.

The self-support amount is defined as taxable income minus one third of the MTAWE (Male Total Average Weekly Earnings). The self-support amount will be the same for both parents. In 2025, the MTAWE is $89,523, meaning the self-support amount is $89,523 / 3 = $29,841.

 BobMary
Taxable Income$99,841$59,841
Self-support amount$29,841$29,841
Child support income$70,000 ($99,841 – $29,841)$30,000 ($59,841 – $29,841)

Bob’s child support income is $70,000 and Mary’s is $30,000.

  1. Calculate the combined child support incomes.

$70,000 + $30,000 = $100,000

  1. Calculate each parent’s income percentage.

  • Bob: ($70,000 / $100,000) x 100 = 70%

  • Mary: ($30,000 / $100,000) x 100 = 30%

  1. Determine each parent’s percentage of care.

Bob cares for the child 3 nights each fortnight, while Mary cares for the child the remaining 11 nights. Bob is a regular carer, and Mary is the primary carer.

  1. Determine the cost percentage.

Using the standard cost percentage table, Bob’s cost percentage is 24% and Mary’s is 76%.

  1. Calculate each parent’s child support percentage.

  • Bob: 70% – 24% = 46%

  • Mary: 30% – 76% = -46%

Since Mary’s child support percentage is negative, she will receive child support.

  1. Work out the cost of each child.

Bob and Mary have one child aged 9. With a combined child support income of exactly $100,000, they fall within the $89,524 to $134,285 bracket. The cost calculation is $14,324 plus 12 cents for each dollar their combined child support income exceeds $89,523.

Calculation:

  • $100,000 – $89,523 = $10,477

  • $10,477 x $0.12 = $1,257.24

  • $14,324 + $1,257.24 = $15,581 (rounded)

The annual cost of their child is $15,581.

  1. Calculate child support amount.

Bob’s payment is calculated as follows:

  • $15,581 x 46% = $7,167 annually

This means Bob must pay $7,167 per year in child support to Mary, approximately $137.83 per week.

For the latest details on minimum and maximum child support payments and specific conditions, parents should directly refer to Services Australia for accurate and up-to-date guidelines.

Child support is generally updated each financial year or when Services Australia receives new income details. It may also change if care arrangements shift.

Yes. Parents can enter into a Binding Child Support Agreement or a Limited Child Support Agreement. These give both parents more certainty and control over how payments are made.

If a parent doesn’t supply income details, child support services can use a provisional income to estimate payments or may be able to obtain the information through the tax office.

Child support usually ends when a child turns 18. Support may continue into adulthood if the child is completing secondary school or has a disability that affects their ability to support themselves.

Child support payments are designed to cover the comprehensive expenses associated with raising a child. These expenses encompass the child’s accommodation, education, medical care, and overall welfare.

The objective is to guarantee that children benefit from sufficient economic support from both parents, addressing their requirements like apparel, nutrition, accommodation, and involvement in after-school activities.
