Today, the majority of new cars on the market have ISOFIX but if you are looking at buying a used car, ISOFIX is not a guaranteed feature and fitment can vary based on the car’s specific manufacturing date, series, badge, or even trim level. So how can you identify ISOFIX (International Standards Organisational Fix) anchorage points on your car?
Since Australia came (late) to the ISOFIX party in 2012, manufacturers have gradually included the feature on their cars but even today it is not a mandatory feature for all new vehicles. So what is ISOFIX and does your car have it?
While Europe and the US have used ISOFIX since the early 2000s, ISOFIX legislation in Australia lagged behind the rest of the world with the adoption of the technology only coming under Australian/New Zealand Standards 1754, with manufacturers given the option of when (or if) to incorporate it in new models from late 2012, though ISOFIX specific child car seats were not available to buy in Australia until late-2014.
ISOFIX Australian standards

ISOFIX is a universal product standard used for safely attaching child safety seats in cars.
In Australia, all ISOFIX-compatible seats must meet the AS/NZS 1754 standards, and be up to date with AS/NZS 1754:2024, the most recent version published on 30 September 2024, as explained by ChildCarSeats. Some of these new changes include new detailed provisions for children with disabilities, ISOFIX weight limit increases and mandating lap-belt positioning devices. While America and Europe have adjacent ISOFIX child seat guidelines, it is illegal to use imported ISOFIX car seats in Australia.
How do I know my car is ISOFIX compatible?
There are a number of ways you can check ISOFIX compatibility in your car:
-
Check your car manual: Your user manual should specify whether the vehicle has ISOFIX fittings.
-
Find the ISOFIX symbol: Look for the ISOFIX symbol on your back seats. Different manufactures approach the aesthetics of concealing (or not) the small metal bar which is the ISOFIX anchor point, so if you don’t immediately see the symbol, it might be hidden behind a plastic cap or cloth flap.
-
Search for the anchor points: Look for the anchorage points (a small round bar mounted horizontally) usually found at the base of the back seat where the seat back and the lower cushion meet.
-
Contact your car manufacturer: Transport Victoria recommends contacting your car manufacturer or car dealer to ask if an ISOFIX car seat will be compatible with your vehicle.
What are the benefits of ISOFIX?
There are several benefits associated with ISOFIX seats:
-
Consumer Choice: The rigid bottom connectors and top tether strap allow for less movement. While ChildCarSeats emphasises that ISOFIX seats are just as safe as traditional child car seats which use adult seat belts in the installation, they provide parents with greater choice on the kinds of seats they can use for their child.
-
Easier to install: ISOFIX uses a click-in and click-out system, making it easier to correctly install and adjust your children’s car seats and switch the child seat between different vehicles.
-
Reduced installation errors: The ISOFIX connectors attach directly to anchor points in your car, meaning there’s less room for error during installation. Lower installation errors means a higher likelihood of your child being adequately protected in the event of a collision.

Safety information for child car seats
All child safety seats sold in Australia must follow the standards set out in AS/NZS 1754.
All national child car seat laws and regulations must be followed in all states and territories across Australia
Top tether strap
Top tether straps are mandatory Australian Design Rule items for child car seats including ISOFIX compatible child car seats.
A top tether strap stops the car seat from rolling forward in a crash, separate from ISOFIX low anchorages or vehicle seatbelts, as explained by ChildCarSeats.
ISOFIX low anchor points

The lower anchor points in a vehicle’s ISOFIX system are designed to connect to the child seat’s lower attachment points. These connectors can be either rigid or flexible, depending on the model of the ISOFIX car seat, according to ChildCarSeats.
