CTP Insurance in Australia: What It Covers (and Doesn't)
CTP insurance is compulsory for every registered vehicle in Australia, but it does not cover what most people think. What you actually get, state by state.
By Timothy Hirou GaschereauPublished 10 min read
Most Australians assume their rego covers them. It does not, not really. CTP insurance, the cover baked into or attached to your registration, is one of the most misunderstood parts of owning a car here. People confuse it with comprehensive and assume it covers damage. It does not, and that misunderstanding can cost tens of thousands of dollars.
Here is the plain-English version of what CTP actually is, what it does and does not cover, how it works differently in every state, and why you almost certainly need more cover on top. General information only, not advice, and we do not recommend specific insurers.
🎯 The essential: CTP (Compulsory Third Party) is mandatory for every registered vehicle; you cannot register without it. It covers your liability for injuries or death you cause to other people, and nothing else. It does not cover damage to any vehicle or property (including your own car), so it is very different from comprehensive. In NSW, QLD and the ACT you buy it separately (a "green slip"); in VIC, SA, WA, TAS and NT it is bundled into your rego. For real protection, most drivers add third party property damage or comprehensive.
What CTP insurance is
CTP stands for Compulsory Third Party insurance, the legal minimum motor cover in every state and territory. It covers your legal liability for injuries or death caused to other people in an accident involving your car: pedestrians, passengers, cyclists and people in other vehicles.
The "third party" is the injured person: you are the first party, your insurer the second, the injured person the third. CTP exists so that person can get treatment and compensation regardless of whether you could personally afford to pay.
What CTP does NOT cover (the big misconceptions)
This is the part that matters most, so bluntly:
- Not your car. Not a scratch, not a write-off.
- Not someone else's car or property. Reverse into a fence or a parked car and CTP is irrelevant.
- Not theft or fire.
- Not your own injuries in fault-based states if you caused the crash.
The classic trap: you rear-end a Ferrari and the driver is injured. CTP covers their medical bills, which is exactly its job. But the Ferrari's $40,000 in panel repairs? Entirely your problem, unless you also have third party property damage or comprehensive. This catches drivers out every day.
The four tiers of car insurance (where CTP sits)
Think of car insurance as a ladder. CTP is the bottom rung, and the gap to the next rung is big:
| Cover type | What it adds | Compulsory? |
|---|---|---|
| CTP (Compulsory Third Party) | Injuries/death you cause to other people | Yes |
| Third party property damage | Damage you cause to others' vehicles and property | No |
| Third party fire and theft | The above, plus your car if stolen or fire-damaged | No |
| Comprehensive | All of the above, plus damage to your own car | No |
ASIC Moneysmart cites a real case of a CTP-only driver who hit a sports car and faced a $20,000 personal loan for the repair. If you could not absorb a large repair bill, it is worth at least third party property damage. See our guide on how to compare car insurance.
How CTP works by state
CTP is not a national scheme; each state runs its own, with different administrators, fault rules and ways of paying:
| State | How you get it | Scheme |
|---|---|---|
| NSW | Buy a green slip from a licensed insurer (shop around) | No-fault (minor) + fault (serious) |
| VIC | Included in rego via the TAC charge | No-fault |
| QLD | Choose an insurer at registration (limited choice) | Fault-based |
| SA | Bundled into rego (Motor Accident Injuries Scheme) | No-fault |
| WA | Bundled into rego (ICWA) | Fault-based |
| TAS | Bundled into rego (MAIB charge) | No-fault |
| NT | Bundled into rego (MACC) | Fault-based |
| ACT | Buy from a licensed insurer (some choice) | No-fault |
Fault vs no-fault matters: in a no-fault scheme, injured people can claim regardless of who caused the crash; in a fault-based scheme, they generally must prove the other driver was at fault, and an at-fault driver's own injuries may not be covered. Rules are complex and change, so check your state's authority.
How much CTP costs
Cost varies by state, vehicle, driving history and location. Where you buy it separately (NSW, QLD, ACT) you pay a premium directly to a licensed insurer: in NSW, typical passenger-vehicle green slips often land somewhere around $500 to $900 depending on your risk profile and postcode. Where it is bundled into rego (VIC, SA, WA, TAS, NT), the CTP component is part of your total registration fee and is not a standalone price you can shop around.
Where you can compare (NSW, QLD, ACT), it is worth it: NSW's SIRA runs a Green Slip Price Check tool, and a few minutes of comparison can save a meaningful amount each year.
How to buy or renew CTP
- Bundled states (VIC, SA, WA, TAS, NT): you pay it automatically when you register or renew. Nothing extra to do.
- Green-slip states (NSW, QLD, ACT): get a CTP policy from a licensed insurer before you can complete registration. In NSW, buy the green slip then register through Service NSW; in QLD, choose your insurer at rego.
Driving without valid CTP means you are unregistered and uninsured: fines apply, and you are personally liable for any injuries you cause, potentially without limit. Not a risk worth taking.
Common misconceptions
- "My car is covered if I crash." No, CTP covers injuries to people, not vehicle damage.
- "I am covered if I get injured." Only in no-fault states; in fault-based states an at-fault driver may not be able to claim.
- "CTP covers property damage." No, that needs third party property or comprehensive.
- "All states work the same." No, the process, administrators and fault rules differ everywhere.
- "If I have CTP I am fully insured." No, CTP is the floor, not the ceiling.
❓ Frequently asked questions
Is CTP insurance compulsory in Australia?
+
Yes. Compulsory Third Party insurance is mandatory for every registered vehicle in every state and territory. You cannot legally register a car without it. In some states it is bundled into your registration fee; in others (NSW, QLD, ACT) you buy it separately before completing registration.
What does CTP insurance actually cover?
+
Your legal liability for injuries or death you cause to other people in a motor accident, including pedestrians, passengers, cyclists and people in other vehicles. It does not cover damage to any vehicle or property.
Does CTP insurance cover damage to my car?
+
No. CTP does not cover damage to your car, to another person's car, or to property of any kind. For vehicle damage you need third party property damage or comprehensive car insurance on top of your CTP.
What is a green slip?
+
A green slip is the common name for CTP in NSW (and sometimes QLD), historically printed on green paper. In NSW you must buy a green slip from an authorised insurer before you can register, and you can compare prices with the SIRA Green Slip Price Check tool.
How is CTP different from comprehensive car insurance?
+
CTP covers injuries to other people only. Comprehensive covers your own car (accident, weather, fire, theft) plus damage you cause to other people's vehicles and property. CTP is the legal minimum; comprehensive is the most complete cover.
What happens if I drive without CTP insurance?
+
Your vehicle is unregistered, so you face fines and, far more seriously, you are personally liable for any injuries you cause to others, which can run to hundreds of thousands of dollars with no insurance behind you. It is one of the biggest financial risks a driver can take.

The bottom line
CTP protects other people from your mistakes; it does nothing for your car or their car. It is the legal minimum, not a complete insurance solution. Know which system your state runs, compare the green slip if you can, and unless you could shrug off a $20,000-plus repair bill, add at least third party property damage on top. That gap between the bottom rung and the next one is where the real financial risk lives.
