car seat law checker — is my child legal? (Australia)

this calculator provides estimates based on published government rates and formulas. your actual entitlement may vary based on your full circumstances. always check with Services Australia for a precise figure.
how the rules work: Australian Road Rule 266 applies nationally. states and territories can add rules, but the age-based minimums are the same everywhere. all restraints must comply with AS/NZS 1754.
sources: Australian Road Rules, Kidsafe Australia, state transport authorities (Transport for NSW, Department of Transport VIC, TMR QLD, etc.).
professional fitting: Kidsafe and authorised restraint fitters can check your installation. book via kidsafe.com.au — even correctly chosen restraints are often installed incorrectly.
this tool gives a clear verdict based on the age-based rules. it does not replace fitment checking. always have new restraints professionally checked and re-check after moving vehicles.
