I agree - ADRs set the minimum standards for new vehicles in Australia - the States cannot over ride them from the point of setting lower standards but can require higher standards.
An example of this was Electronic Stability Control - may have changed now but was not an ADR requirement so vehicles could be sold in Aust without it but Vic said that any vehicle sold there had to have it - as a result some Chery models could not be sold in Vic but were elsewhere in Aust and a few 4wds like the Patrol had to seek exemptions.
Where any State legislation conflicts with Commonwealth legislation, Commonwealth legislation applies and overrides State legislation.
