To legally drive a car in Australia, the vehicle needs to be registered. Registering a vehicle requires it to have a Compulsory Third Party (CTP) insurance policy in place. CTP insurance is attached to a car, not to an individual, so if you’re buying a second-hand car, it will often already have CTP insurance in place.
Beyond the CTP insurance, you aren’t required to hold car insurance to drive a car in Australia. However, some car loans and other car finance arrangements may require you to hold a car insurance policy as part of the car loan’s terms and conditions.
If you do choose to take out insurance on your car, you could select a more basic Fire & Theft policy, or a Comprehensive policy that provides more in-depth coverage. Generally, the more thoroughly a policy covers your car, the more the policy may cost.
