Child Car Seat Rule Changes in Melbourne – Laws Explained
As a parent, your child’s safety is your highest priority, especially on the road. New changes coming into effect in 2025 are set to make Victoria’s streets even safer for our youngest passengers. The Melbourne Child Car Seat Rule 2025 introduces stricter, clearer guidelines that every parent and guardian must know. While adapting to new rules can feel daunting, these updates are designed with one clear goal: to provide the highest level of protection for your child in the event of a collision.
Understanding these changes from the new booster seat mandate for children under 145 cm to compulsory ISOFIX anchors is not just about avoiding penalties; it’s about giving you the peace of mind that comes from knowing your child is secured by the latest and most effective safety standards.
Summary of Key Child Car Seat Rule Changes in Melbourne
1. Stricter Booster Seat Rules (Height-Based)
- New Rule: Children must use a booster seat until they reach 145 cm in height, regardless of their age. This means a 9 or 10-year-old who is under 145 cm will still need a booster.
- Reason: Ensures the vehicle’s adult seat belt fits correctly over the child’s shoulder and lap, providing proper protection in a crash.
2. Mandatory ISOFIX Installation
- New Rule: All newly purchased child car seats must have ISOFIX connectors.
- Reason: ISOFIX provides a more straightforward and secure installation by anchoring the seat directly to the vehicle’s chassis, reducing the risk of incorrect installation with a seatbelt.
3. Taxi and Rideshare Requirements
- New Rule: All taxi and rideshare drivers must have at least one approved child restraint available for families traveling with children.
- Reason: Standardizes child safety across all forms of transport, closing a previous loophole where parents often had to travel without a seat in these vehicles.

This table summarizes the phased implementation of the new laws:
| Age Group | Seat Type | Key Requirement | Law Effective Date |

Action Steps for Melbourne Parents
- Measure Your Child’s Height: The most significant change for many will be the 145 cm height rule for booster seats. Measure your older children to see if they are affected.
- Check Your Current Seats: Ensure your existing car seats are not expired, damaged, or recalled. They must comply with the Australian/New Zealand AS/NZS 1754 standard (check the label).
- Consider an ISOFIX Seat: If you are purchasing a new seat, you must now choose one with ISOFIX. Check your vehicle’s manual to confirm it has ISOFIX anchor points.
- Get a Professional Check: The Victorian Road Safety Authority is offering free inspection camps. Use them to ensure your seat is installed correctly and meets the new standards.
- Plan for Taxis/Rideshares: You can now expect a child restraint to be available when booking a taxi or rideshare. It is the driver’s legal responsibility to provide one.
