Repair and re-register the vehicle while interstate
If you own a light vehicle that's been written-off interstate, it must be repaired, inspected, and registered interstate before you can apply for NSW registration. You'll need to follow the rules that apply for written-off vehicles in that state.
Get the vehicle inspected by the Vehicle Identity & Inspections Unit (VIIU) in NSW
The Transport for NSW Vehicle Identity & Inspections Unit inspects all interstate registered written-off vehicles before they are registered in NSW.
