Cover types, costs and 2026 rules

CTP in each state, the three types of private car insurance, what sets your premium and the consumer rules in force in 2026.

Australian car insurance has two layers. Compulsory third party (CTP) is tied to your registration and covers injuries to people. It is run or regulated by each state and territory, so the way you buy it and what it pays differ between Sydney, Melbourne, Brisbane, Adelaide, Perth, Hobart, Canberra and Darwin. Everything else is optional private insurance: third party property, third party, fire and theft and comprehensive.

The guides in this section explain each layer, then look at the price itself: the rating factors insurers use, the GST and state stamp duty added on top, and whether agreed value or market value suits your car. A separate guide summarises the consumer protection rules that apply to car insurance as of October 2026, from the duty to take reasonable care to renewal notices and unfair contract terms.

Start with the overview of car insurance in Australia if you are not sure which cover you need, or go straight to CTP by state if you are renewing your rego. Figures in examples are illustrative, not market prices; always check the Product Disclosure Statement (PDS) and your state's official CTP site.
