Car insurance in Australia is really two subjects wearing one name: the compulsory injury cover built into (or bought alongside) your registration, which differs in every state and territory, and the optional cover for vehicles and property, which works much the same everywhere. These are the questions we're asked most, answered briefly — each one links to the detailed guide where the full story lives. We've written a dedicated insurance guide for every state and territory: NSW, Victoria, Queensland, Western Australia, South Australia, Tasmania, the ACT and the Northern Territory — plus a look at how the rest of the world does it.
General information only — not financial advice. Cover differs between policies, so the Product Disclosure Statement (PDS), not the marketing page, is what a claim is decided on.
FAQs
Is car insurance compulsory in Australia?
The injury part is: every state and territory requires compulsory third party (CTP) cover, collected with registration everywhere except NSW, where you buy the green slip separately before registering. Cover for damage to vehicles and property is optional in every jurisdiction — legal to skip, expensive to regret.
What does CTP insurance actually cover?
Injuries to people hurt in a motor accident — treatment, and depending on the state, income support and lump-sum compensation. It pays nothing for damage to any vehicle or property, including your own. That distinction is the single most misunderstood fact in Australian car insurance.
Do I need to buy CTP separately, or is it part of my rego?
In NSW you buy a green slip from a licensed insurer before registering. Everywhere else it's collected with your registration payment — visibly in Victoria (the TAC charge) and invisibly in most of the rest. Our state guides cover each scheme's mechanics.
Which states let me choose my CTP insurer?
NSW (competitively priced — shopping around genuinely saves money), Queensland and South Australia (regulated panels, so prices sit close together), and the ACT. Victoria, Western Australia, Tasmania and the Northern Territory each run a single scheme with no choice on the compulsory part.
What's the difference between third party, fire and theft, and comprehensive?
Third party property damage covers what your car does to other people's vehicles and property, nothing on your own car. Third party fire and theft adds your own car, but only against fire and theft. Comprehensive covers both sides plus storm, hail, flood and vandalism, subject to the PDS. Moneysmart has a neutral rundown.
What is a no-fault scheme, and which states have one?
A no-fault scheme pays an injured person's treatment and support without first proving who caused the crash — single-vehicle accidents included. Victoria, Tasmania, the NT and the ACT run substantially no-fault schemes; NSW pays defined benefits regardless of fault for an initial period; and every jurisdiction now covers catastrophic injuries no matter who was at fault.
Am I covered if the crash was my own fault?
For your injuries: in the no-fault jurisdictions above, generally yes; in the fault-based ones, generally only if another party was at least partly responsible — with catastrophic injuries covered everywhere. For your car: only if you hold comprehensive cover. Third-party-only cover pays for the other side, not yours.
Is a car insured when I buy it with registration?
Only for injury compensation — the CTP travels with the rego in every state. No property cover of any kind comes with a purchased car, so arrange at least third party property cover before driving it home; most insurers can start a policy immediately by phone or online.
What happens to insurance when I sell my car?
The rego and its CTP stay with the vehicle. Your comprehensive or third party policy doesn't — cancel or transfer it once the sale completes, and most insurers refund the unused premium. Lodge your state's notice of disposal promptly so fines and liability follow the new owner.
What if I'm hit by an uninsured or unregistered driver?
For injuries, every state scheme has a nominal-defendant or equivalent mechanism so crash victims aren't left uncovered. For damage to your car, comprehensive cover responds and your insurer pursues the other driver; without it, recovering repair costs from an uninsured driver personally is possible but often slow and uncertain.
Does comprehensive insurance cover flood and hail?
Usually, but not universally — most mainstream comprehensive policies include flood and hail, while some budget products exclude or cap them. Given Australia's recent flood and hailstorm record, read those clauses in the PDS before choosing a policy on price alone.
Do modifications affect my insurance?
Yes — undeclared modifications are a common reason claims get contested, and declared ones can raise the premium or require a specialist insurer. Our modified cars guide covers how insurers treat them.
How can I pay less for car insurance?
The reliable levers: re-quote every renewal rather than rolling over, raise the excess to a level you could absorb, pay annually instead of monthly, keep the car garaged where possible, and check agreed versus market value on older cars. In NSW, compare green slips too — it's the one state where the compulsory part rewards shopping.
What about insuring a classic or a car that's off the road?
Specialist enthusiast policies work differently — agreed value negotiated upfront, limited-use pricing, and laid-up cover for cars under restoration. Our guide to insuring a classic walks through the mechanics and the questions to ask.
