car seat laws Australia — every state and territory
milly is a child passenger safety advocate and mum of two who has researched car seat regulations across all Australian states and territories.
Australian car seat laws are based on national rules (Australian Road Rules, Rule 266), so the core requirements are the same in every state and territory. the rules are based on your child's age and determine which type of restraint they must use, and where they can sit in the car.
where states differ is in fines, demerit points, and a few local details. tap any state below for the full breakdown including fines, exemptions, and fitting advice.

what is ISOFIX?
ISOFIX is an international standard for attaching child restraints directly to a car's chassis using built-in anchor points, rather than relying on the seatbelt alone.
since November 2014: all child restraints sold in Australia must be ISOFIX-compatible, and all new passenger vehicles must have ISOFIX anchor points fitted.
ISOFIX provides a more secure and easier installation — look for the ISOFIX-compatible label when purchasing a child restraint. if your car was built before 2014, check your vehicle manual to see if ISOFIX points have been fitted.
taxi and rideshare exemptions
children under 7 are exempt from child restraint requirements in taxis and rideshare vehicles (e.g. Uber, Didi, Ola) if no restraint is available. however, they must sit in the back seat.
children under 1: must be held by an adult passenger in the back seat if no child restraint is available.
tip: if you frequently use taxis or rideshare, consider a portable travel harness or lightweight booster seat that you can carry with you. your child is always safest in a proper restraint.
