Overview of Australia’s 2025 Child Seat Rules
In 2025, Australia’s child car seat laws will undergo significant changes aimed at improving the safety of young passengers. The updated regulations emphasize the proper use of child seats based on a child’s age, height, and weight. These changes are in line with global best practices for child passenger safety and aim to reduce injuries and fatalities in car accidents.
The new rules make it clear that rear-facing seats are essential for younger children, and booster seats must be used until children reach a certain height. These measures are designed to ensure that every child is appropriately restrained, offering maximum protection in the event of an accident.
New Requirements for Child Car Seats
The new rules for child car seats in 2025 are designed to ensure that children are safely restrained according to their size and age. The following categories outline when each type of seat should be used:
Rear-Facing Restraints for Infants
Children under the age of 2 must be secured in a rear-facing child car seat. Rear-facing seats are considered the safest option for young children because they offer the best protection for their head, neck, and spine in the event of a crash. Experts recommend keeping children rear-facing for as long as possible, ideally until the age of 4.
Forward-Facing Car Seats
Once children turn 2, they may transition to a forward-facing car seat with an inbuilt harness. However, it is recommended that children remain in forward-facing restraints for as long as possible, until they outgrow the seat’s weight and height limits. Forward-facing seats provide additional protection for older children while still supporting their bodies during travel.
Booster Seats for Older Children
Booster seats are now required for children until they reach a height of 145 cm. This height requirement ensures that the seatbelt fits properly across the child’s lap and chest, reducing the risk of injury during a crash. Children under this height should not use a regular adult seatbelt. Parents should ensure that booster seats are used correctly and that children are seated properly, with the seatbelt crossing the middle of their chest and hips.
Transitioning to Seatbelts
Once children reach 145 cm, they may begin using an adult seatbelt, provided it fits properly. The seatbelt should sit low across the child’s hips, with the shoulder belt crossing the middle of their chest and not their neck. A simple “5-step test” can help parents determine if their child is ready to safely use an adult seatbelt:
- The child’s back is against the seat.
- The child’s knees bend comfortably at the edge of the seat.
- The lap belt fits low across the child’s hips.
- The sash belt crosses the middle of the child’s shoulder and chest.
- The child can maintain this position throughout the entire trip.
Penalties for Non-Compliance
The Australian government takes child seat safety seriously, and there are significant penalties for failing to adhere to the new child seat rules. Parents and caregivers who do not use the correct restraints may face fines and demerit points. For example, in Queensland, fines can reach up to $1,200 for incorrect child restraint usage, with repeat offenders facing higher penalties.
In New South Wales, a fine of $350 is imposed for non-compliance, along with 3 demerit points. Double demerit points apply during holiday periods to further deter unsafe practices. These penalties reflect the seriousness with which authorities are treating child passenger safety.

Ensuring Proper Installation
Proper installation of child restraints is critical to ensuring maximum safety. In Australia, it is recommended that parents have their child seats installed by a qualified technician or at an authorized fitting station. Regular checks should be performed to ensure that the restraint is securely fastened and that the harness is positioned correctly.
Additionally, it’s essential not to modify or add accessories to a child seat unless they are approved by the manufacturer. Misuse or incorrect installation can reduce the effectiveness of the restraint in a crash.
Exemptions and Special Considerations
While the updated child seat laws apply to most parents, there are some exceptions:
- Medical Needs: Children with medical conditions or disabilities may require special car restraints. In such cases, parents should obtain a medical certificate and follow recommendations for appropriate restraint devices.
- Taxis and Ride-Sharing Services: In taxis or ride-sharing vehicles, parents can use their own child seats. Drivers are not required to provide them, though some services may offer them upon request. Parents should always check with the service provider ahead of time.
