Every registered motor vehicle in New South Wales needs CTP insurance, also known as a green slip, before you can complete your vehicle’s registration. The importance of CTP greenslips in NSW goes beyond ticking a box for rego.
This compulsory third party CTP cover protects injured people after a motor vehicle accident and stops you from carrying medical expenses and compensation claims on your own.
The price gap between each CTP insurer can be $300 or more for the same NSW CTP insurance cover, so comparing matters.
Why is CTP Important in NSW?
CTP insurance compulsory exists for two reasons: it is the law, and it looks after people. The NSW CTP insurance scheme, run by SIRA (the State Insurance Regulatory Authority), makes sure every vehicle on the road has CTP cover in place before the driver can register their vehicle or renew it.
When a motor accident injures someone, CTP cover can pay for medical treatment, rehab, and some lost income for injured people, including passengers, other drivers, pedestrians, and other road users.
Without this cover, costs for injuries caused in a serious driving offence or everyday accident can run high, and you may be personally liable for compensation claims.
CTP looks after people. Car insurance looks after cars and property. The NSW CTP scheme spreads motor accident costs across all vehicles registered in the state, so road users get care when crashes happen.

What Does a CTP Green Slip Actually Cover?
A CTP green slip is compulsory third-party insurance that covers costs when people are injured in a motor vehicle accident involving your vehicle. Your green slip insurance responds to whether you are driving or another driver has permission to use your motor vehicle.
CTP insurance cover can help pay for:
- Medical expenses — ambulance, hospital, physio, counselling
- Medical treatment and rehab for motor accident injuries
- Part of lost income while injured people recover
- Some statutory benefits for at‑fault drivers (up to 52 weeks under the current NSW scheme)
CTP does not cover:
- Damage to your own vehicle
- Damage to other people’s vehicles or other vehicles
- Cover damage to other property or property theft
- Towing, hire cars, or repairs
If you want cover damage, cover loss, or protection for your own vehicle, you need extra cover such as third party car insurance (sometimes called third-party car insurance) or comprehensive car insurance.
Check your PDS — insurers vary on what each product includes.
CTP Cover vs Extra Cover in NSW
CTP insurance cover (NSW) | Needs extra cover |
Injuries sustained by road users in a motor vehicle accident | Damage to your own vehicle |
Medical expenses and some rehab costs | Damage to other people’s vehicles and other property |
Part of lost income for injured people | Property theft and non‑injury events |
Some benefits for at‑fault drivers under the scheme | Repairs, towing and hire car costs |

What Are the Green Slip Benefits for NSW Drivers in 2026?
Because CTP insurance is compulsory, it can feel like another registration fee. But your green slip offers more than a line on a renewal notice.
When a crash happens, current NSW CTP insurance means injured people can access medical expenses and support through the scheme instead of relying on someone to pay out of pocket.
- For drivers, that structure lowers the chance of being sued personally for injury costs, especially where a CTP claim involves long‑term care or complex compensation claims.
- Licensed insurers use dedicated claims teams who know the NSW CTP scheme, so injured people are guided through their CTP claim step by step.
- Some licensed insurers also bundle green slip insurance with other products, which can help car owners manage their insurance premium across CTP and car insurance in one place.
Any discounts usually apply to other policies, not the CTP premium itself, but the combined package can still help if you want extra cover.

Real Experiences from NSW drivers
Driver | What changed | Why it mattered |
Jack | CTP linked with Service NSW by 9 am next day, at a lower price | Fast renewal, no extra calls or paperwork |
Andrew | Saved $250+ on his CTP insurance renewal using the calculator | Same NSW CTP cover, less spent |
Asif | Paid almost $300 less for his green slip | Quick online purchase plus savings |
Jack from NSW had a worry-free experience last month despite initial concerns. His CTP green slip came through the next morning at 9am – and cost $20 less than the initial estimate.
“Everything was smooth and great,” he shared. His NSW CTP insurance was processed overnight and connected seamlessly with Service NSW for his vehicle registration.
Andrew saved over $250 on his annual CTP insurance renewal.
“Amazing prices!! Great customer service!” he wrote in his review. By comparing all six insurers through Greenslips 4 Earth’s calculator, he found a CTP green slip quote that beat his previous insurer by hundreds. His purchase added another tree to the 30,000+ already planted across NSW.
Asif Ali discovered massive savings, almost $300 less than his previous year’s green slips.
The process took minutes: “Very simple and easy to pay,” he noted. His light vehicle now has competitive NSW CTP premiums while his purchase supported native habitat restoration.
The CTP insurance documents electronically arrived immediately, ready for his renew registration process.
What Happens If You Don’t Have a Green Slip?
If you drive without a valid CTP green slip in NSW, your vehicle’s registration is not current, and you are driving an unregistered motor vehicle.
Transport for NSW can issue fines, cancel your vehicle’s registration, and apply penalties. In some cases, it may be treated as a serious driving offence or a driving offence on your record.
The bigger risk is money. Without compulsory third-party CTP, you may be personally responsible for medical expenses, lost income, and other compensation claims for injured people if a motor vehicle accident involves your car.
Even if you have paid for a green slip, it needs to match your registration period. Keep an eye on your due date and register your vehicle on time.
With and Without CTP
If your CTP is current | If your CTP has lapsed |
Vehicle’s registration can be renewed | Vehicle may be unregistered in NSW |
Scheme covers costs for eligible injuries caused in an accident | You may carry the cost of compensation claims personally |
You avoid registration‑linked penalties | You risk fines and driving offence penalties |
What Makes Your CTP Insurance Premium Higher?
Under SIRA rules, each CTP insurer can vary its insurance premium within set bands. Price moves with risk. Key factors:
- Driving history: a serious driving offence or multiple infringements can lift your CTP premium
- Claims history: at‑fault claims from earlier motor accidents sit on your record and raise costs
- Vehicle details: vehicle’s age, body type, and garaging postcode all matter
- Registration period: a 6‑month vs 12‑month registration period changes how much you pay at once
- Registration fee and fund levy: a levy is built into every CTP policy to support lifetime care for people with very serious motor accident injuries
Information Gain: What This Looks Like for a Real Driver
Say you are a 22‑year‑old P2 driver in western Sydney, driving a 2018 Corolla. Your driving history is clean, but your age and licence type push you into a higher‑risk band.
Your postcode adds to the base rate because accident frequency is above the state average. On top of that, the fund levy (currently around $169 for Sydney metro light vehicles) is added to every CTP policy.
By comparing all six CTP insurers through the calculator, you might find a gap of $200–$300 between the cheapest and most expensive quote for the same statutory cover.
That gap is why learner drivers, young drivers and car owners with older vehicles benefit most from comparing before they pay.

Is CTP the Same as Car Insurance?
No. CTP insurance and car insurance do different jobs, and most NSW car owners need both.
Type of cover | What it protects | When you buy it |
CTP green slip (compulsory third party) | Injured people after a motor vehicle accident | Before you register your vehicle in NSW |
Third party car insurance | Other people’s vehicles and other property | Optional — you choose |
Comprehensive car insurance | Your own vehicle, plus third party damage and property theft | Optional — common for newer cars |
CTP sits underneath these policies as the compulsory third-party layer every vehicle on NSW roads must have, whether or not the driver adds extra cover.
How Does CTP Work Across Australian States and Territories?
Every state and territory in Australia has a form of compulsory third party insurance or MAI insurance. The goal is the same (protect injured people) but the rules differ.
- In New South Wales, CTP is a separate CTP green slip sold by licensed insurers.
- In Queensland, the Motor Accident Insurance Commission oversees CTP.
- In Victoria, the Transport Accident Commission manages motor accident compensation.
- South Australia, Western Australia, the Australian Capital Territory and the Northern Territory each run their own versions of third party CTP insurance or MAI insurance.
If you drive across states and territories, your NSW CTP cover usually still applies to injuries, but claims may go through a different authority.

People Also Ask About Greenslips Prices and Concerns
These are some of the most common questions NSW drivers ask about CTP green slips, answered based on current SIRA and NSW Government rules.
1. Does CTP follow the car or the driver?
CTP insurance attaches to the vehicle, not the driver. If your motor vehicle is involved in an accident, the CTP policy on that vehicle responds regardless of who was driving (as long as they had permission). That is why your CTP green slip is tied to the vehicle’s registration, not your licence.
2. Can I choose my own CTP insurer in NSW?
Yes. NSW is one of the few states and territories where you pick your own CTP insurer from the licensed insurers approved by SIRA. There are currently six — AAMI, Allianz, GIO, NRMA, QBE and Youi. Statutory CTP insurance cover is set by the scheme, so the core benefits are the same across all insurers. The main differences are price, service, and any bundling options.
3. Does my NSW CTP cover me if I drive interstate?
Your NSW CTP green slip covers injuries to other people caused by your vehicle anywhere in Australia. However, cover for your own injuries depends on the CTP laws of the state or territory where the crash happened, not your NSW policy. In some states, you may only be covered if someone else was at fault. SIRA recommends considering private health or travel insurance for additional protection when driving interstate. Check with SIRA or the local motor accident authority for full details.
4. How long do I have to report a CTP claim in NSW?
You have 28 days from the date of the motor vehicle accident to lodge a CTP claim if you want back‑dated statutory benefits (lost income and medical treatment) from the day after the accident. If you miss that window, you still have up to 3 months to lodge, but you may lose early pay for lost income.
5. What does CTP protect that car insurance doesn’t?
CTP protects injured people, medical expenses, medical treatment, rehab and lost income after a motor accident. Car insurance (third-party car insurance or comprehensive) protects vehicles and property. CTP does not cover damage to your own vehicle, other people’s vehicles, or other property. Car insurance does not cover personal injury claims. Most NSW car owners need both.
