Car insurance in Australia ranges from compulsory third party through to comprehensive cover, and what's compulsory varies by state. This page is general information, not a quote.
CTP (green slip) insurance
Compulsory third party insurance, sometimes called a green slip, covers injury to other people if you're at fault in an accident, and is generally required to register a vehicle — in some states it's bundled with registration, while in others (like NSW) you choose your own CTP insurer separately.
Third party property versus comprehensive
Third party property cover generally pays for damage you cause to someone else's vehicle or property, but not your own car — comprehensive cover extends to your own vehicle as well, for theft, fire, and accident damage regardless of fault.
What affects your premium
Premiums are generally affected by your driving history, the car's make, model and age, where you live and park, and your chosen excess — a higher voluntary excess typically lowers the premium but increases your out-of-pocket cost when you claim.
Key takeaways
Compare comprehensive quotes even if only third party property is compulsory in your state — the cost difference is sometimes smaller than expected relative to the extra cover.
