VIC ROADS : "Children under 6 months must use a rearward-facing approved child restraint and travel only in the rear row. If your car does not have a rear row, this does not apply. However, a rearward-facing child restraint cannot be used in the front seat where there is a passenger airbag. A rearward facing child restraint allows a child to lie down and, in a crash, gives support and protection to the head and neck - the most vulnerable parts of a child's body."
