Vehicle inspection in Australia is done on a state basis. Each state or territory has the authority to set its own laws pertaining to vehicle inspections, all (with the exception of the self-governing territory of Norfolk Island) have some form of inspection, either periodically or before a transfer of ownership. vehicle inspection is required before a vehicle can be registered for the first time, after a lapse in registration, if a vehicle has received certain modifications, or has been cited for safety faults (a yellow sticker) by the police.
