Australia has also begun to enforce new child car seat safety legislation to improve child passenger safety in every state and territory, beginning in 2025. The new guidelines are grounded on the recent research and best practices on safety and security internationally, which focus on the right type of seat, depending on child height and weight, better seat installation criteria and enforcement.
Major Changes in 2025 Child Car Seat laws
– Rear-Facing Seats: Children should also remain in rear facing car seats at least to the age of 2 years of age which is an increase of age limit to 1 year. Rear facing seats offer better support to cushion the head and neck of toddlers in case of accidents.
– Forward-Facing and Booster seats: The children between 6 months and less than 7 years old should use a forward-facing seat or booster seats that match the Australian standard AS/NZS1754:2025. The booster seats are required up to around 145 cm in height of the children.
– Height/Weight Over Age: The new regulations give height and weight of the children more importance than age itself to decide on the restraint. This compromise embraces different child development.
– ISOFIX Anchorage: New vehicles should have supported the use of the ISOFIX anchor systems which enable easier and safer child seat fitting. Where possible, parents should use ISOFIX since it provides better compliance and crash safety.
– Correct fit Checks: Child restraints must be properly installed to avoid abuse. The seats need to be inspected on a regular basis regarding wear and validity (usually after 10 years or after the accident).
– Taxi/Transport Rules: Taxis and ride-share vehicles must now offer a certified child seat to occupants under the age of 7, which will guarantee uniformity in safety measures across transportation modes.
– More Serious Consequences: Failure to comply may result in a fine up to AUD 750 and demotion, and even legal proceedings.

Government Support and Awareness
– Citywide car seat safety checks and a seat fitter are being extended at no or reduced costs.
– Awareness campaigns and workshops are used to educate the parents about new rules and safety best practices.
– There is need to label car seats clarifying that the seat was found to be in compliance with the 2025 standards to facilitate parental choice.
