Green Slip vs Comprehensive Insurance: What Each Covers

A lot of people find out what their green slip doesn't cover at the worst moment, standing next to a dented car. The green slip is compulsory, so it feels like "the" car insurance. It isn't. It covers injuries to people, and nothing about the cars. This guide sets out the four types of car insurance side by side, using SIRA's and Moneysmart's descriptions as we read them on 30 October 2026.

It does not consider your objectives, financial situation or needs. We are not an insurer or broker, we don't sell green slips and we don't recommend any insurer. SIRA (the State Insurance Regulatory Authority) is the official source of green slip information in NSW, so check its website or your insurer before you act. Facts were checked on 30 October 2026.

The short answer

A green slip is compulsory third party (CTP) insurance. SIRA says it covers your liability for injuries or death caused to other people by your vehicle, and it doesn't cover damage to vehicles or property. You need it to register most vehicles in NSW.

Comprehensive insurance is the opposite end. It's optional, and it covers damage to your car and other people's cars or property, even if you caused the crash, plus theft, fire and weather damage, subject to exclusions.

So the dividing line is simple: people on one side, cars and property on the other.

The four types of car insurance

The federal government's Moneysmart car insurance guide (updated 23 October 2026) describes four main types.

A few points the table can't show:

• Comprehensive cover can be agreed value or market value. Moneysmart explains that an agreed value is fixed between you and the insurer and may reduce each year, while market value is set by the insurer at the time of the claim.
• Exclusions differ between policies. Moneysmart gives examples such as wear and tear, intentional damage and damage caused by an unlicensed, drunk or drug-affected driver.
• None of the property policies replace CTP. You still need a green slip to register, whatever else you hold.

"Third party" means two different things

This is where most of the confusion starts. "Third party insurance" can mean compulsory third party (the green slip) or third party property damage. They share two words and cover completely different things.

• Compulsory third party is about people: injury or death caused by a vehicle.
• Third party property is about things: damage your car causes to other people's cars or property.

So if someone says "I've got third party", it's worth asking which one. A driver with only a green slip has no cover for damage to anyone's car.

What happens after a crash if you only have a green slip

Picture a crash you caused, with damage to two cars and a sore neck for the other driver.

• The other driver's injury. That's what CTP is for. The injured person can claim through the CTP scheme. Our CTP claims guide explains how.
• Their car. Your green slip won't pay for it. Without third party property or comprehensive cover, the repair bill may fall to you.
• Your car. Your green slip won't pay for this either.

Moneysmart gives the example of a driver with only CTP who hit a new sports car and had to take out a $20,000 personal loan to cover the repairs. Its point is that damage to other cars can be expensive, and CTP doesn't touch it.

Injury cover reaches further than many people expect, though. SIRA says the current scheme gives drivers and third parties some cover regardless of fault, unless the driver is charged with a serious driving offence. Our guide to CTP injury benefits explains what can be claimed and when benefits are limited.

Does comprehensive insurance cover injuries?

Moneysmart describes comprehensive cover in terms of damage to cars and property, theft, fire and weather, not injuries to people. Injury cover for NSW crashes comes through the CTP scheme, which is why a registered vehicle still needs a green slip when it also has comprehensive cover. Some policies come with extras, so the product disclosure statement is the place to check what a particular policy includes.

How comprehensive cover can affect your green slip price

Here the two products do meet. SIRA's How prices are set page (updated 15 January 2026) lists whether you have comprehensive insurance among the rating factors insurers may use for green slips. Other factors on the list include drivers' ages, driving history, demerit points, claims history, vehicle age and where the vehicle is parked.

How much it matters, if at all, is up to each insurer within SIRA's rules. It doesn't change the cover. SIRA says all green slips give the same level of CTP cover, though the prices may differ. SIRA's free Green Slip Price Check shows CTP quotes from all licensed insurers. It compares green slips only, not comprehensive or property policies. See our green slip cost guide for how prices are built.

Questions Moneysmart suggests asking yourself

Moneysmart doesn't tell you which type to buy, and neither do we. It does suggest some questions to think through, including:

• Could you manage without your car if it was damaged, stolen or written off?
• Could you afford to repair or replace your car without insurance?
• Could you afford the cost of other cars or property you damaged by accident?
• Is your car parked on the street or at higher risk of theft?
• If the car is financed, does the lender require a minimum level of insurance?

Moneysmart also notes that if you want cover for repairs to your own car after a crash you cause, you usually need comprehensive insurance.

What this means for you

Your green slip deals with injuries. Everything to do with repairing or replacing cars sits with separate, optional policies. When you look at what you hold, check the full name of each policy rather than the words "third party".

If you're looking into property cover, Moneysmart's guide explains the options, and the product disclosure statement for any policy sets out what it does and doesn't cover.

Frequently asked questions

Does a green slip cover damage to my car?

No. A green slip covers injuries to people. It doesn't cover damage to your car or anyone else's car or property.

Is a green slip the same as third party insurance?

It's compulsory third party insurance, which covers injuries. Third party property insurance is a different, optional policy that covers damage to other people's cars and property.

Do I need a green slip if I have comprehensive insurance?

Yes. Comprehensive is optional property cover. You still need CTP to register most vehicles in NSW.

Is comprehensive insurance compulsory in NSW?

No. Of the four types Moneysmart describes, only CTP is compulsory.

Can having comprehensive insurance change my green slip price?

It can. SIRA lists having comprehensive insurance among the rating factors insurers may use, but how each insurer applies it varies.
