Choosing a car seat is one of the first big safety decisions you make as a parent, and the shop shelves don’t make it easy. There are capsules, convertibles, harnessed seats and boosters, all with different age ranges and fitting systems.
We fit child seats for babies a few days old right through to seven-year-olds on boosters. Here’s the process we’d follow if we were buying a seat for our own family.
Step 1: Start with what NSW law requires
In NSW, every child under 7 must travel in an approved child restraint that suits their age and size. The minimums are:
- Under 6 months: a rear-facing seat (usually a capsule or a convertible seat in rear-facing mode).
- 6 months to under 4 years: a rear-facing seat, or a forward-facing seat with an inbuilt harness.
- 4 to under 7 years: a forward-facing seat with an inbuilt harness, or an approved booster seat.
- 7 and over: a booster or anchored safety harness until they’re tall enough for an adult seatbelt. The suggested minimum height for an adult belt is 145cm.
These are legal minimums. Safety groups recommend keeping children in each stage for as long as they fit, rather than moving them up early.
Step 2: Look for the AS/NZS 1754 label
To be legal in Australia, a child restraint has to meet the Australian/New Zealand Standard AS/NZS 1754. Approved seats carry a label saying so, both on the box and on the seat. Seats bought overseas or from international websites often don’t meet this standard, even if they’re excellent seats, so they can’t be used here.
Step 3: Use the shoulder height markers, not just age
Australian seats have shoulder height markers that show when your child fits the seat and when they’ve outgrown it. Children grow at different rates, so a tall 3-year-old may need the next seat before a smaller 4-year-old does. Check your child’s shoulders against the markers every few months.
Step 4: Make sure it fits your car
Not every seat suits every car. Some are wide, some need a lot of room behind the front seat when rear-facing, and some suit ISOFIX anchor points better than seatbelt installation. Before you buy, ask the store if you can try the display model in your own car. If you have more than one child, check that everyone can still reach their seatbelt buckle once the seats are in.
Step 5: Get it fitted properly
A good seat that’s fitted badly won’t protect your child the way it should. Transport for NSW recommends using an authorised restraint fitter or fitting station, and you can find one through Service NSW. If you fit it yourself:
- use either the seatbelt or the ISOFIX connectors, not both
- push down firmly on the seat while you tighten it
- attach the top tether strap if the seat has one
- check the harness isn’t twisted, and do the pinch test: if you can pinch the strap at your child’s shoulder, it needs tightening
Step 6: Be careful with second-hand seats
A hand-me-down can be fine, but only if you know its history. The seat should be less than 10 years old (check the date stamp or sticker), carry the AS/NZS 1754 label, have no cracks, mould or frayed straps, and come with its instructions. Never use a seat that has been in a crash. If you can’t confirm where it’s been, don’t use it.
Step 7: Keep little ones out of the front
In a car with two or more rows, children under 4 can’t sit in the front. Children aged 4 to 7 can only sit in the front if the back seats are already taken by younger children. Never put a rear-facing seat in a front seat that has an airbag.
What happens when your car seat stays at home?
This is where many parents get caught out: at the airport, on holiday, or on a night out when the family car isn’t coming.
Under NSW point-to-point transport rules, rideshare and hire car drivers must have children under 7 in an approved restraint, and they can turn you away if there isn’t one. Standard taxis only have to restrain babies under 1, so older children can legally ride with just a seatbelt. Legal isn’t the same as safe, though, and most standard taxis don’t carry child seats at all.
That’s what Sydney Baby Taxi is for. When you book a taxi with car seat through us, you tell us your children’s ages and we arrive with the right capsule, car seat or booster already fitted to Australian standards. We can fit up to three child seats in one car.
