Although there is currently no law prohibiting the use of restraints older than 10 years, it is strongly recommended by the manufacturers not to do so; for the following reasons: It’s not possible to guarantee a restraint that’s older than 10 years will perform as it was originally intended to do so. The Australian Standards have been improved significantly in past years with updates occurring in 2000, 2004, 2010 and 2013. Older restraints will not meet new improved design features. If you choose to use a restraint over 10 years and it fails in a crash, not only are you putting the child at higher risk of injury, but you may also see your insurance payout reduced for failing to follow the recommendations of the manufacturer.
