Also, they're from Australia and I've heard that their car seat laws are inadequate. It was probably the norm then. Her memorial page...

It says that "currently a child over the age of ONE is legally allowed to be moved into a child booster and restrained only by an adult [belt]

[edit] Australian Regulations
AS1754By law every child restraint sold in Australia must carry the Australian Standard AS/NZ1754 sticker (pictured right). Most overseas child restraints, including restraints from countries such as the UK and USA, do not comply with these Standards and cannot legally be used in Australia.
Children under one must be restrained in a suitable, approved child restraint.
Passengers aged one year and over, but under 16 years, must occupy a seat fitted with a seat belt or suitable child restraint, if such a seat is available.
The responsibility for children under 16 years using restraints correctly rests with the driver. Penalties for drivers not ensuring their passengers, under the age of 16, are properly restrained involve a fine of $165 and three demerit points or, if convicted in court, a fine of up to $500 and three demerit points. Possible suspension or cancellation of licence may also apply.[2]
Exemptions to the law:
If a child under one is travelling in a taxi and a suitable restraint is not available, provided the child does not travel in the front seat.
If a child is travelling in a police or emergency vehicle.
If a child has a medical condition or physical disability that makes it impractical to use a child restraint, and the driver has a certificate from a doctor indicating this is the case.[3]
How sad for these Australian kids.
