As the name implies, Compulsory Third Party or CTP insurance is a mandatory requirement to drive in Australia. Every state and territory requires a CTP insurance policy to be in place to register a vehicle to be legally driven. In some states and territories, you can choose your CTP insurer, while in others the CTP insurance is included as part of the registration process, and paid for alongside the other registration fees.
CTP insurance offers the most basic level of car insurance cover – it only covers the cost of medical bills for third parties injured in an accident where you are the at-fault driver. For example, if you crashed into another car and injured the other driver, your CTP insurance policy should cover the cost of their hospital stay.
