Keeping children safe on the road is every parent’s top priority. From 2025, Australia has updated its child car seat regulations to ensure better protection for infants, toddlers, and young passengers. These changes align with the latest safety research and require families to review their current car seat setups.
Below is a clear breakdown of what’s new, what parents should do, and how to stay compliant.
Key Updates to the 2025 Child Seat Laws
The revised laws emphasize age- and height-appropriate restraints for longer periods. They also align across most states under national safety standards, though some small variations remain.
Main changes include:
- Rear-facing seats used longer – infants and toddlers must remain in rear-facing restraints at least until age 2, with some states recommending even longer.
- Forward-facing to booster transitions clarified – booster seats remain mandatory until a child reaches 145 cm in height.
- Adult seat belt use only after 145 cm – children below this height must stay in boosters regardless of age.
- Stricter compliance enforcement – fines and demerit points apply for misuse or non-compliance.
Age and Height Guidelines
| Stage | Requirement | Approx. Duration |
|---|---|---|
| Rear-facing | Mandatory until at least age 2 | 0–2 years (longer recommended) |
| Forward-facing with harness | After outgrowing rear-facing seat | ~2–7 years |
| Booster seat | Required until child reaches 145 cm | ~7–12 years |
| Adult seat belt | Only if 145 cm+ and belt fits correctly | 12+ years |
Tip: Always check your seat’s weight and height limits in addition to these age rules.
Correct Installation Matters
Improperly installed seats are one of the biggest risks in car accidents. Parents should:
- Follow the manufacturer’s installation guide carefully.
- Ensure harnesses are snug and correctly positioned.
- Use the right seat-belt path for the seat type.
- Visit local council or child safety centres offering free installation checks.

- Check your child’s height, weight, and age regularly.
- Replace old or expired car seats that don’t meet 2025 standards.
