CTP insurance costs vary depending on your state or territory, vehicle type, registration category and the way the local scheme is administered. In some places, CTP is included in the registration process or set under a regulated scheme, while in others you choose an approved insurer and prices can differ. Your registration renewal notice or the relevant state transport authority will show the applicable amount. Check the official government website for your state, or contact an approved CTP insurer, for a current quote based on your circumstances.
