CTP insurance is mandatory in all Australian states and territories. New South Wales calls it green slip insurance, and NSW is the only place where you buy it as a separate policy and pick your own insurer. Everywhere else, the premium is collected with your vehicle registration.
That one difference is why green slip prices matter so much to NSW vehicle owners and barely register anywhere else.
What CTP Insurance Covers
CTP insurance covers personal injury claims when someone is hurt or killed in a road accident involving your vehicle. It pays for medical treatment, rehabilitation, lost income and care, and it protects you from the cost of certain injuries you cause to other people: drivers, passengers, riders, cyclists and pedestrians.
It pays nothing toward vehicle damage. Two other insurance products handle that:
- Third party property insurance covers damage you cause to other people’s vehicles and property.
- Comprehensive insurance covers other people’s vehicles plus your own car.
Neither one is compulsory, and neither replaces CTP.
Two more slips get muddled with green slips in NSW. A pink slip is the annual safety inspection report for older registered vehicles. A blue slip is the unregistered vehicle inspection, needed at first registration in NSW, when bringing a used car in from interstate, and when registration has been expired more than three months.

New South Wales: The Only Competitive Green Slip Market
Six insurers issue CTP green slips in NSW: AAMI, Allianz, GIO, NRMA Insurance, QBE and Youi. Allianz absorbed the old CIC Allianz licence in March 2019, and Youi joined as the sixth green slip provider in December 2020. Older guides still listing CIC Allianz are out of date.
Each private insurer sets its own prices inside a framework the State Insurance Regulatory Authority oversees. The statutory cover is identical no matter who you buy from, so the same vehicle can attract six different quotes for the same protection.
Green slip prices vary based on vehicle and driver details. What moves your premium:
- Vehicle class: passenger vehicles, light vehicles and light goods vehicles are rated separately, and a ute often costs more than a sedan.
- Garaging postcode.
- Age of the youngest listed driver.
- Driving history, including recent demerit points and any driving offence.
- Previous personal injury claims.
- GST registration, since an input tax credit entitlement changes what you pay.
A good driving record and a clean claims record usually put you near the cheapest prices available for your vehicle. Young drivers and those with poor driving history pay more, which is exactly when comparing prices earns its keep.
You can compare green slip prices before purchasing by using our green slip calculator. Green slips are mandatory for vehicle registration in NSW, so do this before your expiry date. Miss the deadline by more than three months and your registration is cancelled, which means new plates, a blue slip and a full 12-month policy.
Victoria
Victoria’s government underwrites CTP through the Transport Accident Commission. The Transport Accident Charge appears as its own line on your registration renewal, alongside the registration fee and insurance duty. Rates are set by vehicle class and garaging risk zone, with concessions for eligible pensioners. There is no separate policy to buy and no insurer to select.
Queensland
Queensland’s CTP is included in vehicle registration fees, but you nominate which insurer holds the policy. Three private insurers hold licences from the Motor Accident Insurance Commission: Suncorp (AAI), Allianz and QBE. RACQ left the scheme in October 2023, and neither AAMI nor NRMA underwrites Queensland CTP.
Insurers file premium rates within floors and ceilings that MAIC sets, so the spread between cheapest and dearest is narrow compared with NSW. Queensland CTP is fault-based, with a separate no-fault scheme covering catastrophic injuries from July 2016.
South Australia
South Australia switched to a market model where CTP stays in your registration but you choose the insurer. Five approved insurers operate: AAMI, Allianz, NRMA, QBE and Youi. Youi entered the scheme in July 2022, and SGIC — which older articles still name — now trades as NRMA Insurance. The CTP Insurance Regulator supervises the scheme.
Western Australia
Motor injury insurance on WA registered vehicles covers injuries caused to others in a crash anywhere in Australia. The Insurance Commission of Western Australia is the sole compulsory motor injury insurer, and it assesses claims on fault. Premiums arrive with registration fees, and a catastrophic injuries scheme was added from July 2016.
Tasmania
CTP is included in vehicle registration costs, with the premium automatically included in the registration fee. The Motor Accidents Insurance Board is the single provider. MAIB also issues CTP-only cover for vehicles that do not need Tasmanian registration, such as some off-road vehicles.
Northern Territory
The Motor Accidents Compensation Scheme is a no-fault scheme covering treatment, rehabilitation and support for people injured in a motor vehicle accident. It sits inside your registration. The Motor Accidents Compensation Commission administers the scheme and has appointed TIO, a Northern Territory division of Allianz Australia Insurance Limited, as claims manager.
Australian Capital Territory
The Australian Capital Territory calls its scheme Motor Accident Injuries insurance, which replaced CTP for accidents from February 2020. Four private companies hold MAI licences: AAMI, APIA, GIO and NRMA Insurance. Premiums are bundled with registration, and the Motor Accident Injuries Commission reviews insurer rates and conduct.
Why Prices Vary So Much Between States
The underwriting model explains most of the gap. Government-managed schemes show less variation in CTP pricing because one body sets one rate per vehicle class. Where private insurers compete, each applies its own rating factors, and the spread widens.
CTP pricing in New South Wales is competitive and moves with individual risk. A clean record works in your favour. Recent demerit points or a young driver on the policy work against you, and that is precisely when checking all six prices is worth ten minutes.
People Also Ask
These are the questions NSW and interstate drivers ask most about green slips and CTP insurance. Every answer reflects the licensed insurer lists and scheme rules current at July 2026.
1. Is CTP insurance compulsory in every Australian state?
Yes. CTP insurance is mandatory in all Australian states and territories. Only New South Wales makes you buy it as a separate green slip before registering. In Victoria, Queensland, South Australia, Western Australia, Tasmania, the Northern Territory and the ACT, the premium is collected with vehicle registration.
2. Which insurers sell green slips in NSW?
Six insurers hold SIRA licences to sell CTP green slips in New South Wales: AAMI, Allianz, GIO, NRMA Insurance, QBE and Youi. Allianz took over the former CIC Allianz licence in March 2019, and Youi became the sixth licensed insurer in December 2020.
3. What does CTP insurance cover?
CTP insurance covers personal injury claims when someone is killed or injured in a road accident involving your vehicle. It pays for medical treatment, rehabilitation, lost income and care for injured people, including passengers, cyclists and pedestrians. CTP covers no vehicle or property damage, which needs third party property insurance or comprehensive insurance.
4. Why do green slip prices differ between insurers?
Each licensed insurer sets its own green slip prices inside the framework SIRA regulates. Insurers weigh vehicle type, garaging postcode, the youngest driver’s age, driving history and past claims differently, so identical cover produces six different quotes. Comparing prices at every renewal is the only way to see the gap.
5. Can I compare CTP prices outside New South Wales?
Only partly. In Queensland, South Australia and the ACT you pick an insurer from a licensed list, but regulators cap the premium range tightly. Victoria, Western Australia, Tasmania and the Northern Territory each run one government scheme, so no competing prices exist to compare.
6. Who sets green slip prices in NSW?
Insurers set their own green slip prices. The State Insurance Regulatory Authority regulates the NSW CTP scheme, approves insurer premium filings and publishes the Green Slip Price Check so drivers can view every licensed insurer’s quote side by side. SIRA does not set the prices itself.
7. What is the difference between a green slip, a pink slip and a blue slip?
A green slip is your CTP insurance policy. A pink slip is the annual safety inspection report required for older registered vehicles. A blue slip is an unregistered vehicle inspection, needed at first registration in NSW, for interstate transfers, and when registration has been expired more than three months.
8. What happens if my green slip expires?
No vehicle can be registered without a current green slip, and driving unregistered is illegal. Once registration lapses past three months it is cancelled, and starting again requires a blue slip and new plates. Lapsed CTP also leaves you personally liable for injuries you cause in a road accident.
Compare Green Slip Prices in NSW
If your vehicle is registered outside NSW, your CTP premium already arrives with your registration and there is nothing to shop around for. Check your state’s regulator in the table above for further details and contact details.
If you drive on New South Wales roads, you need a green slip before registration, and what you pay depends on which of the six insurers you choose. Our green slip calculator pulls current rates from every approved provider, including at-fault cover options.
When you buy an eligible green slip through Greenslips4Earth through our environmental partner,trees are planted. The planting is funded by us as the provider, so it is not added to your CTP insurance premium and it does not change the regulated price you pay.
