Insurance Commission of WA
If you have been injured in a motor vehicle crash, you can claim for support when: you were driving a vehicle, and the driver of the other vehicle caused the crash (ie they were at fault) OR you were a passenger, pedestrian or cyclist/scooter rider and the driver of the vehicle was at fault. The vehicle that caused the crash needs to be registered in Western Australia to make a claim. You may not be able to claim if: you were totally at fault a pedestrian, cyclist or scooter rider caused the accident the person at fault was the driver of a vehicle licensed in another state or territory. If the vehicle at fault is unidentified or unlicenced, you may still be able to claim. In the case where you sustained catastrophic injuries because you were at fault or no-one driving was at fault, you can claim under the Catastrophic Injuries Support Scheme.
