In an effort to enhance road safety for children, the Australian government has updated its child car seat regulations for 2025. These changes are designed to ensure better protection for children in the event of an accident, based on research into the effectiveness of various types of restraints. Here’s what you need to know about the updated child seat rules, including the new guidelines on child seat types, usage, and compliance.

The updated child seat regulations for 2025 reflect the Australian government’s ongoing commitment to improving road safety for children. By adhering to these new rules, parents and caregivers can provide the safest travel environment for young passengers. It is essential for all Australian drivers to stay informed about these updates and ensure that their children are correctly restrained according to age, size, and weight. The new rules are designed to protect the most vulnerable passengers on the road – our children – and to reduce the risk of injury in the event of a car accident.

Key Changes in the Child Seat Laws for 2025
The updated child seat regulations in Australia for 2025 provide clearer guidelines to help parents and guardians choose the correct restraints for their children, depending on age, height, and weight. The following changes are significant:
1. Rearward-Facing Seats for Infants
- Under 6 months: Children must be seated in rearward-facing seats, which offer the highest level of protection for infants. This is especially important for the child’s head, neck, and spine during a collision.
- 6 months to 2 years: If possible, children should remain in rearward-facing seats for as long as their size allows, as this position continues to provide critical protection.
2. Forward-Facing Seats
- From 2 to 4 years: After 2 years of age, children can switch to forward-facing seats with a built-in harness. Parents should ensure the child seat complies with AS/NZS 1754 standards, which is mandatory in Australia for all approved child restraints.
3. Booster Seats
- From 4 to 7 years: Children in this age group should use booster seats to ensure that the seatbelt fits properly across the child’s chest and hips. Booster seats must be used until the child is tall enough to safely wear an adult seatbelt.
4. Adult Seatbelts
- 7 years and older: Children may use adult seatbelts, but only if they meet the 5-step test. This test ensures that the lap belt fits across the child’s lap and the shoulder belt fits across the chest. The recommended height for using an adult seatbelt is generally 145 cm.
Other Important Guidelines
Front Seat Restrictions
- Under 4 years: Children cannot sit in the front seat of vehicles equipped with airbags unless all rear seats are occupied by children under 7 years.
- 4 to 7 years: Children in this age group may sit in the front seat, but airbags must be deactivated, and the seatbelt must be used correctly.
- Under 12 years: Children should not sit in the front seat of a vehicle with airbags unless absolutely necessary.
Correct Installation
- One of the most common errors parents make is incorrect installation of child seats. In 2025, there is an emphasis on ensuring that child restraints are installed properly, either using the ISOFIX system or a seatbelt.
- It is recommended that parents have their car seats checked by a professional installer to ensure proper fitting and safety.
Who is Responsible for Ensuring Correct Use?
It is the driver’s responsibility to ensure that children are seated in the appropriate restraints. This includes ensuring that the seatbelt or car seat is correctly installed and that children are properly restrained. Failure to comply with the law can result in fines and demerit points.
Why These Changes Were Necessary
According to the Australian Transport Safety Bureau (ATSB), child restraints are one of the most effective ways to protect young passengers in the event of a crash. In 2025, these updates reflect new evidence about the efficacy of different types of car seats. In particular:
- Rearward-facing seats offer the best protection for infants.
- Booster seats ensure that seatbelts fit properly for children who have outgrown forward-facing seats.
- Ensuring children use the correct seat for their size and weight significantly reduces the risk of injury.
How Parents and Carers Can Prepare
- Check for Compliance: Ensure your child’s seat meets the Australian/New Zealand Standard AS/NZS 1754. This standard applies to all approved child restraints.
- Adjust as Needed: As your child grows, adjust the harnesses, headrests, and seat positions to fit their size. Don’t switch to a seatbelt or booster seat too early.
- Installation: If you’re unsure whether the car seat is installed correctly, visit a professional or a certified installation service.
- Avoid Second-Hand Seats: Always check the history of second-hand seats. If the seat has been in a crash, or is more than 10 years old, do not use it.
Enforcement and Penalties
Parents and guardians who fail to comply with the new child restraint laws could face fines and demerit points. Ensuring that your child is in the correct restraint not only promotes safety but also helps avoid legal consequences. The fines for non-compliance can be substantial, making it imperative for all drivers and carers to understand and follow the updated rules.
