The ultimate guide to baby and child car seats

Baby in an infant car restraint in Australia In Australia, by law, all children up to the age of seven years should be seated in a suitable infant or child car restraint when travelling in a car. But child safety is more than just following the law – there are many factors to consider when deciding what restraint to buy for your child and when to move them up to the next level of restraint.

The most important thing is that your child is in the car restraint appropriate for their size and they should remain in it for as long as they fit – even if they are older than what the law states. You should also take great care to ensure the seat is installed correctly and the child is properly secured.

The child restraint laws were introduced in all Australian states and territories to reduce the number of children being prematurely moved to the next level of child restraint (or to no child restraint at all) and to reduce the effects of serious injury or death in an accident.

Here is our ultimate guide to infant and child car restraints to help you make sure your child is as safe as possible while travelling in a car.

4 important things all parents MUST know about child car restraints

  1. All children must be, by law, in a child restraint until the age of seven.
  2. The seat must be the appropriate seat for the child’s size and age.
  3. The seat must be installed correctly. A poorly installed seat can be very dangerous.
  4. The child must be properly fastened and the harness properly adjusted.

How do I know which car restraint is the right one for my child?

The law specifies which type of car seat your child should be in. BUT, it is important to remember that child restraint laws are based on the child’s age to make them easy to follow and enforce. Your child’s seated height should also be considered when buying a car seat (or converting to the next type) to ensure they are in the right seat and are therefore as safe as possible. If you have a tall child you should ask for advice on which brands of child seat are best for taller children.

The law specifies that:

  • Babies aged up to six months – a rear-facing carseat or baby capsule
  • Children aged six months to four years – a rear-facing or forward-facing car seat with in-built harness.
  • Children four to seven years – Car seat with in-built harness or booster seat used with properly fastened and adjusted adult seatbelt.

There are many convertible carseats on the market – you can buy a rear-facing carseat that turns around to become forward-facing (to suit newborns to age 4+) as well as seats that convert into boosters (to suit ages 6 months – 8 years +).

Also, make sure your child car seat meets with the Australian/New Zealand Standard for child restraints (AS/NZS 1754), recently updated to include ISOFIX. When buying a child restraint, look for the standards approved sticker.

Why do children under the age of 7 need to be in a car seat?

There are a number of reasons that children under seven should be in a car seat:

  • Children in adult seatbelts are 3.5 times more likely to be significantly injured in a crash compared with children in a child restraint.
  • Seatbelts are designed for adults and do not offer enough protection for children. They can actually be harmful in the event of a crash and if used incorrectly or prematurely can increase the risk of injury or death.
  • Children are not big enough to be appropriately restrained by a seat belt alone. Their legs are not long enough to bend at the seat edge and so children slump, pushing the lap part of the belt up into the abdomen area instead of across the thighs. Also the sash part of the belt across the neck can result in serious injury in a crash.
  • Child restraints have inbuilt safety features to protect a child’s head and lower body, such as the wings on each side of the seat. Children in adult seat belts miss out on this customised safety that is designed specifically for their size and weight.

When can children sit in the front seat of a car?

The law is quite specific about when children can sit in the front seat of a car;

  • If a car has two or more rows of seats, then children under 4 years must not travel in the front seat.
  • If a car has two or more rows of seats, then children aged between 4 years and under 7 years must not travel in the front seat UNLESS all other seats are being used by children under 7 years. In this situation, a child may travel in the front seat using an approved booster seat with a properly fastened and adjusted seatbelt.
  • If a car only has one row of seats (eg. a utility or van) then a child can be seated in the passenger seat as long as they are in an appropriate child restraint. A child restraint anchorage point must be available to secure a child car seat for a child under 4 years and and a rear-facing seat should never be installed if there’s an airbag in that position.

How do I ensure my child is as safe as possible while travelling in a car?

It is important to remember that we use car seats to keep children safe – not just to follow  the law. There are many safety recommendations regarding child car seat safety that go beyond the law with the aim of keeping children as safe as possible.

Here are a few ways you can ensure your child is as safe as possible:

Keep them in their current seat for as long as possible

Keep them in their current seat until they outgrow it rather than transition them when they reach the age requirements by law. Newer car seats have shoulder height markers, which make it easier to see when a child has outgrown the seat. Once the child’s shoulders reach the highest marker, the child should move to the next type of restraint (or a more accommodating restraint of the same type), where their shoulders line up with (or are above) the lowest marker. In seats without shoulder makers, you should move your child up when their shoulders are higher than where the harness straps come out (at their highest point).

Remember that babies are safer when rear-facing

A child’s head is heavy and larger than an adults in proportion to the rest of their body. This means they’re at a greater risk of injury in an accident when forward-facing. If your child still fits into a rear-facing seat try to keep them there for as long as you can.

Use booster seats with lap-sash seatbelts

Secure your child in a seat with a built-in harness for as long as they fit, even if they’ve turned four years old. When they do move to a booster seat, only use it where a lap-sash seatbelt is available (not in the middle where sometimes only a lap belt is available).

Use high-back booster seats rather than booster cushions

Small booster cushions are not the safest option. Booster seats with a back and side wings offer more protection.

Don’t use old or damaged car seats

Restraints older than 10 years should not be used and second-hand restraints should be inspected for wear and degradation before use. Damaged restraints and those that have been in moderate to severe crashes – should not be used, and should be disposed of in a way that ensures they can’t be re-used.

Continue using a car seat until the child is 145cm

You child isn’t necessarily ready to use an adult seat and seat belt just because they’ve turned 7. If they aren’t tall enough to use the adult seat it is safer to keep them in a booster seat until they are. In general a child will not fit properly in an adult seat belt until they are about 145cm tall. There’s a five-step test to help you know when your child is ready to move into an adult seat in the car.

How do I know my child car restraint is properly installed?

A child car seat isn’t an easy thing to install correctly – especially if you’ve never done it before or if you are sleep-deprived! Here are some tips on making sure your child car seat is installed properly.

1. Have your child car seat professionally installed.

It is best to have your restraint professionally installed and have the installer talk you through the important steps. Most nursery stores will be able to install a seat you’ve bought from them and you can contact your local motoring authority for details of approved fitters. Some motoring organisations – and some safety bodies, such as Kidsafe and Australian Red Cross will also check or fit seats depending on which state you live in.

2. Read the instructions carefully and keep them handy

Child car seats can be complicated and for your child’s safety you should definitely read the instructions. Some seats have pockets to store the instructions too. Keep the instructions handy as you’ll need them if you move the seat or convert it to the next type of seat. All car seats are different too, so don’t assume that because you’ve installed one type of seat you know how to install another.

3. Make sure the car seat belt is correctly threaded through the back of the car seat

Check your instructions to see exactly how the seat belt should be threaded through the back of the seat.

4. Make sure straps are tight, but not too tight

In a rearward-facing seat the top tether should be connected to the car’s anchor point tight enough to remove any slack but not too tight that it lifts the seat off the car’s seat at the front. In a forward-facing seat you should have the teether strap connected to the car’s anchor point and pulled tight enough to hold the top of the seat in place.

5. Make sure the child restraint sits neatly on the seat of the car

Some backseats in some cars are on quite a steep angle making it difficult for a child restraint to sit neatly on the seat. You can place rolled up or folded towels underneath to stop in moving around on the seat.

How do I make sure my child is properly secured in the carseat?

1. Before installing the seat adjust the shoulder straps to suit your child

Pop your child in the carseat and adjust the shoulder straps so that they come from above the child’s shoulder. If their shoulder is higher than the point at which the straps come out of the seat then the straps will need to be moved a notch higher. If they’re already at the highest point you’ll need to find a seat that can accommodate a taller child. Or failing that move them up to the next type of car restraint.

2. Make sure the harness strapped aren’t twisted

Be careful to put the harness straps in correctly when adjusting them (take notice of how they are before you undo them to adjust). They should not be twisted. Twisted harness straps can injure a child in an accident. To help keep them straight you can loosen the harnesses when you take the child in and out of the seat.

3. Make sure the harness is tight and the child secured

You should be able to place your finger under the harness so that it isn’t too tight. The child should not be able to move his or her arms out from under the harness.

What about children and babies travelling in taxis?

A child under the age of 7 is safest when travelling in a capsule or child restraint correct for it’s age/size. Where possible, it is best if you can supply your own car seat when intending to travel in a taxi to ensure that your child is safe along with being more cost effective. All taxis should have the correct anchor point for fitting the restraint, but it is advisable to call the taxi company in advance to check.

Taxi companies may be able to provide child restraints if they are given sufficient notice. A surcharge is the norm for the hire of the child seat and you will often have to pay for the taxi to collect the seat from a depot or taxi company’s headquarters. Your journey will be metered from the car seat collection point, to wherever you are picked up and then onto your final destination. Check all charges with your taxi company in advance and ensure that you book your vehicle well in advance (at least an hour).

Older children (up to age 7 years) must use a child restraint if one is available.

The rules for travelling in taxis with very young children do vary from state to state in Australia. It is advisable to check with taxi companies when booking and to order a child seat in advance. Customer service desks at airports (in Australia and internationally) should be able to assist you with booking taxis with child car seats if you are not able to pre-book a taxi prior to your arrival. Links to specific laws in each state are at the bottom of this article.

Information about Australian car seats for overseas visitors

All child restraints used in Australia must comply with current Australian standards – one of the main features of which is the use of a rear strap to an anchor point. Australian child restraint standards are some of the most stringent in the world and most overseas child restraints do not comply with these standards and cannot legally be used in Australia – this includes restraints from countries such as the UK and USA.

It is advisable to hire a child restraint in Australia from a reputable hire service rather than bringing your own from overseas.

    The problem is that becoming a parent triggers a whole host of paranoid scenarios. As you’re installing the car seat, your mind wanders. You start to think about the worst car accidents you’ve ever been in or seen, and how you might protect your baby best from that kind of trauma. You worry about whether or not you’ve strapped the base down tightly enough, or (once the baby is born), if you’ve strapped him or her down tightly enough! When driving with the child, you become much more cautious, and (in my experience) far more likely to rail about someone speeding by you than in the past. I believe I will worry till my youngest goes to college…

    Finding the right fitting car seat is so important to protecting loved ones! We are expecting a child soon and we want to make sure that we have the right seats to be able to take her (or him) where ever we need to go. I was unaware that children up to 7 needed these types of seats, but the know you know the better! At least we found this out now.
