❓ Baby Car Seat FAQ

Here’s our baby car seat FAQ, where we try to answer the questions parents have but keep getting confusing answers to. We’ve also listed the individual state government pages where you can read more in-depth information about baby car seats and the law.

If you find any errors, please don’t hesitate to contact us so we can correct the information for other parents.

📅 Booking & Service

What is your service area? ＋
Please refer to our Service Area page.
Can I install my baby car seat myself in Melbourne? ＋
Yes, you can install your own baby car seat — however, many installations aren’t as straightforward as parents believe. What do you do when the seat is contoured and hard to fit, when the back seat is reclined, when you can’t find the anchor point, or when the tether strap keeps falling between the seats, making the fitting loose and unstable? These are problems an accredited ACRI fitter deals with daily, and only ACRI fitters know how to properly resolve them. In Melbourne, contact your nearest ACRI fitter on 0420 516 587.
Do I need a child car seat installation certificate? ＋
As accredited ACRI members, we provide a certificate of installation. Some hospitals may ask to see it, so keep it in your maternity bag for safe keeping.
How long does the child seat installation take? ＋
Each installation is allocated 30 minutes — covering an explanation of how the restraint works, you experiencing how to use it, and the actual installation.
What are your child restraint fitting costs? ＋
Please refer to our Mobile Baby Car Seat Fitting Cost page.
Are all child restraint fitters the same? ＋
No. Some fitters may have done the course years ago and not kept their knowledge up to date. Others may have been approved by RACV, VACC, or even VicRoads — a separate process to ACRI training, and not as comprehensive.

🔧 Isofix & Standards

What is Isofix? ＋
The Australian/New Zealand Standard for child restraints (AS/NZS 1754) was amended to allow manufacturers to include Isofix-compatible lower attachment connectors on rearward and forward-facing restraints. These can be a pair of rigid or flexible connectors, built in at the time of manufacture, connecting to the vehicle’s Isofix low anchorages. Note: not all vehicles are fitted with Isofix anchorages. For more, see our Understanding Isofix article.
What is an “approved child restraint”? ＋

Approved child restraints comply with Australian Standard AS/NZS 1754 and must be correctly anchored using an approved anchorage system. All restraints sold in Australia must meet the strict requirements of AS/NZS 1754, covering materials, design, construction, performance, testing, and labelling — it’s illegal to sell a restraint that doesn’t comply. Restraints bought overseas won’t meet the Australian Standard, and it’s illegal to use them here. Restraints approved to the earlier E46 standard may still legally be used, but aren’t recommended, since they’re old and may have deteriorated to the point of being unsafe.

Look for these labels on a genuinely approved restraint:

Can I use my 10-year-old baby car seat? ＋
There’s no law prohibiting restraints older than 10 years, but manufacturers strongly recommend against it: there’s no way to guarantee an older restraint still performs as originally intended, and the Australian Standards have been significantly improved over updates in 2000, 2004, 2010, and 2013 — older restraints won’t meet these newer design features. If a restraint over 10 years old fails in a crash, your child faces higher injury risk, and your insurance payout may also be reduced for not following the manufacturer’s recommendations.
Can my child use an adult seat belt at 7 years of age? ＋
Children aged 7 to 16 must travel in either an approved child restraint or a properly adjusted, securely fastened adult seat belt — the right choice depends on your child’s size. The average 7-year-old can’t fit an adult seat belt correctly; in fact, most children can’t wear one correctly in most vehicles until they’re 10 to 12 years of age. More information from RAA.

🚗 Seating Position Law

Can children ride in the front seat? ＋

In any vehicle with two or more rows of seats, the law requires: children under 4 must sit in the rear. Children aged 4 to 7 may sit in the front, but only if all rear seats are already occupied by children up to the same age.

Small car exception: if it’s genuinely impossible to fit a third restraint between two others, a child aged 4 to 7 can move to the front row, provided they’re correctly restrained in an age-appropriate restraint.

In a vehicle with only one row of seats, children may travel in that row provided they’re correctly restrained in a size-appropriate, approved restraint, fitted to the manufacturer’s instructions — including attaching the upper tether to an anchorage point (this excludes restraints like foam boosters that don’t have an upper tether).

Commercial vehicles with only one row (e.g. vans like the Toyota Hiace, or utes like the Ford Ranger) aren’t required to have anchorage points, though it may be possible to have one fitted. If your vehicle doesn’t have anchor points, contact RAA or ACRI to find your nearest anchorage installer.

Rear-facing restraints must never be used in a seating position fitted with an airbag. Child restraint manufacturers warn against this, and most vehicle manufacturers warn against placing children under 12 in airbag-fitted positions — since airbags are designed for adult safety, these warnings should be followed.

📜 State-by-State Child Restraint Laws

What are the laws regarding child restraints in my state? ＋

🪑 Restraint Types

What are shoulder height markers? ＋

Since AS1754:2010 was approved, shoulder height markers have been added to all child restraints, making it easier for parents and carers to tell if a restraint still suits their child, and when it’s time to move to the next type or mode (e.g. rear-facing to forward-facing).

Baby capsule or convertible car seat? ＋
Many parents prefer a capsule for the first six months — the benefit is not disturbing your baby’s sleep when transitioning from car to pram. Another great advantage: all you need is a second base in the grandparents’ car, making it much easier if they need to pick up your child from childcare in an emergency. Hiring a second base costs approximately $65–$85 for a couple of months, compared to several hundred dollars for a convertible car seat. A capsule should ideally go on the passenger side — the narrow centre position and the split in the back seat can make it unsafe to install in the middle, where the upper tether may fall between the split. 📋 This page gives a $65–$85 range; the other FAQ page (and the About Us page) states a flat $65. Worth confirming which is accurate.
Should the car seat installation be rock hard? ＋
Many parents believe it should — some fitters even claim no one can install it firmer than they can. Fact: it doesn’t need to be rock hard. Making it rock hard actually compromises the installation and your child’s safety, since a rock-hard seat belt can no longer absorb energy from an emergency stop. A good installer will explain this rather than chase maximum firmness.
Is an extended harnessing (Type G) seat safer? ＋

What is extended harnessing? The child stays in a 6-point harness until they reach a torso length of 51cm — much safer than a standard lap-sash belt, the same reason racing drivers use a 5- or 6-point harness. It was introduced because many parents were moving children into boosters prematurely: old enough (around 4) but not tall enough for the sash to sit correctly across the shoulder rather than near the neck.

Three criteria for a good extended harnessing seat:

  1. A hassle-free harness (no manual re-threading)
  2. Easy one-handed harness adjustment
  3. A good recline angle, to help prevent head flop while sleeping

Seats meeting this criteria include the Maxi Guard, Maxi Guard Pro (around $120 more, with thermo fabric), Infa Grandeur (also an A4 rear-facing restraint), and Infa Evolve.

In this fitter’s opinion, the Maxi Cosi Luna doesn’t meet this criteria and isn’t as good value as the alternatives above.

Compared to boosters: extended harnessing is safer overall. A booster needs the correct age and height first, while an extended harnessing seat can be used immediately once forward-facing, keeping the safety benefit of a 6-point harness throughout.

Can I use a seat belt extender? ＋
It’s not recommended — seat belt extenders haven’t been tested with child restraints, and introduce another possible point of failure. A better solution is a Type G restraint (like the Britax Maxi Guard or Infa Evolve Origin), which keeps your child in the harness until approximately 8 years of age.
