I spoke to my car insurance agency as i was going to import one and they said if the car was involved in an accident and the seat didnt meet australian standards it would void the claim......PHI said the same thing...i can't speak for TAC as I didn't speak to them. You can also be fined if you are caught with one installed but then again I am not sure exactly how observant a police officer is going to be of the exact make and model carseat you have in the car at the time.

Be careful with buying overseas though, just because it rearfaces longer doesn't make it a safer seat...make sure to look very very carefully at all the safety and crash test ratings of the various seats.....some of them are worse than our forward facing seats.....some are really good options but some re really dodgy.
