Western Australia calls the compulsory component Motor Injury Insurance, and it is provided by the Insurance Commission of Western Australia alone. It is built into your registration and there is no choice of provider.
Where Western Australia genuinely differs is not the compulsory part but the optional part, because the state's distances change which policy features actually matter.
The Insurance Commission provides Motor Injury Insurance to every registered vehicle, and separately administers a scheme providing lifetime treatment and care for people catastrophically injured in motor vehicle crashes, funded through the same registration charge. Neither pays anything towards vehicle damage.
In a compact state, towing limits and repairer networks are details. In Western Australia they are the policy. A breakdown on a highway hundreds of kilometres from the nearest town can exceed a standard roadside assistance towing allowance several times over, and a comprehensive policy's own towing and accommodation benefits become genuinely load-bearing rather than nice-to-have.
Perth premiums are moderate and behave like any other capital: density, theft and collision frequency. Outside it, the risk profile inverts — fewer collisions, but far higher consequences when something happens, and a much thinner network of repairers meaning longer off-road time. A hire car benefit is worth more here than the premium difference usually reflects.
It is already included. Motor Injury Insurance is provided by the Insurance Commission of Western Australia through your registration, and there is no separate policy to buy or insurer to choose.
It is Western Australia's name for compulsory third party cover. It covers injury to people arising from motor vehicle crashes and pays nothing towards vehicle damage.
Towing distance limits, hire car benefits and accommodation cover. In a state this large, those determine what actually happens after a breakdown far more than a small premium difference does.
Medicare Levy Surcharge thresholds and government rebate percentages are reviewed regularly, so this page does not quote them. For the current figures see the ATO and the government's privatehealth.gov.au.
