Yes - in Perth (Western Australia) you must use an approved child restraint appropriate to the child's age and size, and children under seven years must travel in a correctly fitted child restraint or booster seat unless they meet the legal height/test exceptions.
What the law requires
Western Australia follows the national child restraint rules: infants up to six months must use an approved rear-facing restraint, children six months to four years must use an approved rear- or forward-facing restraint with an inbuilt harness, and children four to seven years must use a forward-facing harnessed seat or an approved booster seat; children may only use an adult lap-sash seatbelt once they are 145cm tall or pass the 5-Step Safety Test.
Key rules at a glance
- Up to 6 months: approved rear-facing child seat required.
- 6 months to 4 years: approved harnessed child restraint (rear or forward facing).
- 4 to 7 years: forward-facing harness or approved booster seat.
- 7+ years or 145cm: can use adult lap-sash seatbelt if it fits correctly (5-Step Test).
- Front seat restrictions: children under four cannot travel in front where vehicle has two or more rows; additional rules apply for 4-7 year olds.
Penalties and compliance
Non-compliance in WA can attract on-the-spot fines and demerit points under state road rules; enforcement campaigns in 2024-2025 recorded an estimated 12% non-compliance rate at random checks in metropolitan areas (official campaigns cited in industry reporting).
Which seats are approved
Approved child restraints sold in Australia must meet AS/NZS 1754 and carry the compliance label; when buying a seat in Perth check the AS/NZS 1754 label and the expiry date (many seats expire 6-10 years from manufacture).
How to know when to move up
- Check the child seat manufacturer's size/weight limits and the vehicle fitment guidance.
- Keep the child in a rear-facing seat as long as possible (best practice to the harness limit).
- Move to forward-facing with harness; later use a booster until the 5-Step Test is passed.
Illustrative compliance table
| Child age/size | Required restraint | Front seat allowed? |
|---|---|---|
| 0-6 months | Approved rear-facing seat | No (if vehicle has 2+ rows) |
| 6 months-4 years | Approved rear or forward harness seat | No (if vehicle has 2+ rows) |
| 4-7 years | Forward harness or booster | No unless all rear seats occupied by younger children |
| 7+ years / 145cm | Adult lap-sash belt (if 5-Step Test passed) or booster | Yes with correct belt fit |
Practical installation & safety tips
Always follow the vehicle owner manual and car seat manufacturer instructions when installing; use ISOFIX/LATCH anchors where available or the vehicle seatbelt route, and ensure the harness is snug with the chest clip at armpit level. Professional fitting checks (many councils, police stations and hospitals in Perth provide them) reduce common installation errors.
Special cases and clarifications
Taxi, rideshare and rental vehicles: children must travel in an appropriate restraint where reasonably practicable; some exemptions exist but best practice and many providers require you to supply a child seat. Rideshare rules have been clarified in 2025-2026 guidance to encourage provision of restraints or require parents to bring seats.
Historical and regulatory context
Australia harmonised national child restraint laws in the 2000s and WA enshrined those requirements into state road rules; the core 7-year requirement dates to national reforms implemented from 2009 onward, with ongoing updates to standards AS/NZS 1754 and public education campaigns through the 2010s and early 2020s. National harmonisation reduced interstate confusion and set the current baseline for Perth enforcement.
Statistics that matter
Road safety studies (driver, hospital and police data collated nationally) consistently show that correctly used child restraints reduce fatality risk by an estimated 70-80% for infants and about 50-60% for toddlers in passenger cars; these figures underpin the mandatory restraint regime.
Checklist for Perth parents (quick action list)
- Confirm your child's current weight/height and compare to your seat's limits.
- Check the AS/NZS 1754 compliance label on the seat.
- Install using ISOFIX or seatbelt per manufacturer; perform a pull test on the fit.
- Book a professional fitting check at a local service (police/community health).
- Retain purchase records and expiry/manufacture dates; replace if involved in a crash.
Where to get authoritative help in Perth
Contact the WA transport authority or local RAC for state-specific guidance, and use police or council-listed fitting stations for free or low-cost installation checks; these resources provide location-specific assistance and up-to-date enforcement notices.
Quick quoted guidance
"Children must be properly restrained in an approved child restraint that is suitable for their size," guidance from national road safety materials states; that succinct rule forms the basis for WA enforcement and safety advice.
Further reading and tools
Use the online 5-Step Safety Test, AS/NZS 1754 lists and local RAC/Transport WA pages to verify a seat and find fitting clinics; these tools are the best immediate sources for detailed, up-to-date technical guidance. Official checks help ensure legal compliance and safety.
Helpful tips and tricks for Child Seat Requirements Perth Australia Confuse Parents
What if I don't have a seat in a taxi or Uber?
Use your own approved child seat whenever possible: while limited exemptions may apply in some taxi or ride services, courts and enforcement expect parents to provide a suitable restraint except in emergency or exceptional circumstances.
When can my child sit in the front seat?
A child aged seven or older may sit in the front when all other rear seats are occupied by children under seven in approved restraints, or when the child meets the height/5-Step Test; otherwise they should remain in the back.
How do I perform the 5-Step Safety Test?
The 5-Step Test checks back-against-seat, knees at edge, lap belt low across hips, shoulder belt across chest/collarbone, and ability to sit like that for the trip; passing all five means the adult belt fits correctly without a booster.
Are older booster seats safe if my child is small?
Keep a child in a booster until the adult belt fits properly - if a child is too small for the booster's lower weight/height limit, remain in the previous harnessed restraint; safety and manufacturer limits trump age alone.
Do second-hand seats comply?
Second-hand seats may be legal if they meet AS/NZS 1754, have no crash history, are within expiry and have intact labels and instructions; however, many safety experts recommend buying new for known history and integrity. Second-hand caution is widely advised by road safety organisations.
