Child restraints for use in motor vehicles

Check Car seats for children for more information
The mandatory standard for child restraints for motor vehicles came into effect on 7 November 1978 and was last amended 19 September 2014. It covers various requirements for the design, construction, performance, user instructions, marking and packaging of child car restraints.

The amendment to the mandatory standard in September 2014 removed an early (2000) version of the Australian and New Zealand Standard AS/NZS 1754 from the scope of the regulation and replaced it with the 2013 version. As a result, the mandatory standard is now based upon the 2004, 2010 and 2013 versions of AS/NZS 1754.

Parents and carers use child car restraints to keep children safe inside cars.  Restraints are suitable for children usually up to 10 years old with shoulder height of 530 mm. They are fitted in the car and used with existing adult seatbelts.

Under the mandatory standard, a child car restraint is a device used together with an adult seatbelt to restrain a child car passenger and reduce the risk of their bodily injury or death in the event of a car accident.  It does not apply to child restraints designed for children with a disability or to features that already come with the car.

Types of child restraints

There are seven main types of child restraints under the mandatory standard. These are:

Type A: Rearward-facing or transversely installed restraint with a harness or other means of holding the child back



Type A: Rearward-facing only with ISOfix compatible connectors


 Type B: Forward-facing only with rigid ISOfix compatible connectors



 Type C: Forward-facing harness without a chair

Type E: A booster seat used in conjunction with a lap-sash seatbelt suitable for children approximately 4 to 10 years of age whose height is less than 138 cm.


Type F: A restraint that consists of either:

  • a booster seat used in conjunction with a Type C child restraint and a seatbelt, or with a lap-sash seatbelt, suitable for children approximately 4 to 10 years of age, or
  • a converter used in conjunction with a seatbelt, suitable for children approximately 8 to 10 years of age.

Type G: Forward-facing only up to approximately 8 years



Combination Type: Child restraints can also be a combination of the above types. For example, a Type AB or BE converter seat.

Type AB: Rearward-facing



Type AB: Forward-facing 


Type AB: Rearward-facing



Type AB: Rearward-facing with soft ISOfix compatible connectors



Type AB: Forward-facing with soft ISOfix-compatible connectors


Type BE: Booster mode with adult seatbelt


Type BE: With built in harness



Serious injury or death

When children are not properly restrained they are more likely to suffer serious injuries or die in car accidents. A 2007 Australian study confirmed that using adult seatbelts too early, using seatbelts incorrectly and using lap-only seatbelts all increase children’s risk of injury or death. Source: Medical Journal of Australia, June 2007.

Mandatory standard

The mandatory standard is based on the 2004, 2010 and 2013 versions of Australian and New Zealand Standard AS/NZS 1754 Child restraint systems for use in motor vehicles. 

AS/NZS 1754 is a voluntary standard except for those sections in the 2004, 2010 and 2013 versions specifically called up by the mandatory standard. Suppliers must comply with any one of these versions of AS/NZS 1754 with variations outlined in the mandatory standard, which you must consult for these details.

For complete information about all mandatory requirements for child car restraints, we strongly advise that you read Consumer Protection Notice No. 3 of 2014. This information is essential to ensure you and your business comply.

The current mandatory standard came into effect on 19 September 2014.

Does this apply to your business?

Under the ACL supply includes:

  • in relation to goods - (including re-supply) by way of sale, exchange, lease, hire or hire-purchase and
  • in relation to services - provide, grant or confer. 

This mandatory standard applies to anyone in the business of supplying child car restraints, including:

  • manufacturers
  • importers
  • distributors
  • retailers
  • hirers.

To allow for staggered implementation, there are some cases where a mandatory standard or ban prescribes different compliance dates for the manufacturing, importing and supply of a product. Manufacturers, importers and distributors should check for this detail in the mandatory standard before embarking on production, importation or distribution of these goods.


Complying with the mandatory standard

Some key requirements

The requirements noted below are key requirements only. They may help to give suppliers a general idea of the detail they must look up in the mandatory standard. This information may also assist consumers when they are choosing child car restraints.

While we provide some advice on this page to help you understand aspects of the mandatory standard, suppliers must not rely on this information as a complete guide to compliance.

Design and construction

Harnesses and straps

  • There must be upper tether straps to greatly reduce a child’s head jolting forward in a car accident.
  • Forward-facing restraints must have double crotch straps—that is, a minimum five-point harness. Note that single crotch straps can harm the child’s genital area during impact from an accident.
  • The harness should have a single-point adjustment so that the parent or carer can adjust it easily.
  • The harness adjusters must be self locking.
  • The harness should have a quick-release buckle so that the parent or carer can quickly and easily free the child from the restraint.


Covers and liners must be included in the restraint to:

  • cover any polystyrene that could be toxic to a child
  • ensure harnesses aren’t easily twisted or tangled so that they can restrain the child properly and comfortably.


  • Components and accessories must be rigid, not come off and not be sharp or otherwise harmful if a child can access them.
  • The anchoring system must meet certain size and dimension requirements to ensure the child restraint is compatible with different car seats.


  • Components must be durable enough to resist regular wear.
  • Webbing ends must not unthread.

Performance testing

  • Suppliers should have a wide-ranging, dynamic testing method in place that includes these simulated impacts:
    • frontal
    • side
    • rear
    • inverted.
  • Infant crash test dummies must be specially developed—they must meet certain requirements that make them especially flexible.
  • The harness adjustment must be tested for ease of use.


Each child restraint must come with instructions for installation, use and maintenance as well as general information. These instructions and information need to come in a booklet or sheet that must be:

  • attached to the child restraint and removable, or
  • provided in a pocket as part of the child restraint.

ExceptionType C:

For Type C restraints, the booklet or sheet must be in the package with the child restraint.


Suppliers must ensure each child restraint is permanently and legibly marked with various warnings.


The following warnings must appear on all child restraints:

  • Use the restraint exactly as shown in the instructions.
  • Supervision of children is needed because they may be able to undo buckles.
  • Do not alter or modify this restraint.
  • Repairs must only be done by the manufacturer or agent.
  • Do not allow the restraint to come into contact with polishes, oils, bleach and other chemicals.
  • Destroy the restraint if it has been in a severe crash, even if no damage is visible.


There are additional warnings required for each particular type of restraint. Check Table 6.2 in AS/NZS 1754 for specific additional marking requirements.


Child restraint packaging must display the relevant warnings as above.
