Long story short

1
Your compulsory third-party (CTP) insurance details are linked to your rego

They can be checked online for free. For other policies, dig into your desk drawers or emails for policy documents.

2
CTP insurance is compulsory and varies across states and territories

It covers people, not property, and you can’t legally drive without it. In NSW it’s called a Green Slip and must be purchased separately.

3
Third-party car insurance helps you if you damage someone else’s property

It can help you avoid paying thousands out-of-pocket if you’re at fault in an accident.

4
Comprehensive car insurance covers the most and costs the most

It protects your car even if you’re at fault and often includes features like hire car cover or optional extras like reduced excess for window and glass repairs.

What are the different types of car insurance?

Compulsory third-party (CTP)

In a nutshell, compulsory third-party (CTP) insurance covers people, not property. If a car causes an accident that results in personal injury or loss of life to a third party, CTP insurance can cover compensation costs, medical treatment, loss of income, and more. 

CTP insurance is required by law if you want to drive in Australia, and each state or territory takes its own approach to it. For instance, it’s known as a Green Slip in NSW, the Transport Accident Commission (TAC) charge in Victoria, a Motor Accident Injuries (MAI) policy in the ACT – you get the idea. 

So, if you’re researching CTP policies, it’s a good idea to start with how CTP insurance works in your state or territory.

Third-party property

As the name suggests, third-party property insurance covers damage caused by your car to someone else’s car or property. In most cases, a third-party property policy won’t cover damage to your own car.

Third-party, fire, and theft

A third-party, fire, and theft policy offers the same level of cover as third-party property and then some. That is, it might cover your car for fire damage or if it’s stolen and not recovered.

Comprehensive car insurance

A comprehensive policy is the highest level of car insurance you can buy. Unlike third-party car insurance or CTP insurance, comprehensive car insurance covers accidental damage to your car regardless of who’s at fault. 

If you check your car insurance and think you could do better than your current policy, try a car insurance comparison tool to compare car insurance. With iSelect you can compare car insurance policies from a range of insurers and set yourself up with one in minutes – whether that’s a bare-bones third-party property policy or a fully-loaded comprehensive policy with heaps of valuable features and optional extras.

How can I check if my car is insured?

Before we get into the ‘how’, let’s quickly nut out the ‘why’. Typically, you’d do a car insurance check to: 

  • check a car’s compulsory third-party (CTP) cover
  • review your car insurance policy’s coverage or price
  • help decide whether to upgrade or downgrade your cover
  • remind yourself who you’re insured with (it happens!). 

With that out of the way, here’s how you’d typically check your car insurance. 

How to check CTP insurance

Your CTP and rego go hand in hand. You can do a free online CTP insurance check for a car by simply keying in its rego on the state or territory’s website for vehicle registrations. 

How to check comprehensive or third-party car insurance

Unlike CTP insurance details, which are publicly available for registered vehicles, your individual comprehensive, third-party, fire, and theft, or third-party property policy is more of a private matter (as it should be!). 

If you have any one of these three types of policies, here are some ways you could check your insurance. 

Search your email inbox for items like renewal notices, certificates of currency, policy documents, or even your car’s rego. And be sure to check for the most recently dated emails.

Sometimes your insurer might have sent you physical copies of your policy details. So, maybe try rummaging through your home office or console table for documents or unopened envelopes. 

Your bank or credit card statements may also hold clues to who your insurer is – maybe keep a sharp eye out for the direct debits.  

What should I do if my car is uninsured?

First off, if your car is registered, it’s highly unlikely that you’re driving around without compulsory third-party (CTP) insurance. That’s because either it’s included in your rego or you need it to register your vehicle or renew its registration. 

If you find out that you somehow don’t have CTP insurance, you’ll need to buy a CTP policy before you can drive your car – whether that means paying your rego in Victoria, buying a Green Slip in NSW, or otherwise. 

That said, if your insurance stops at CTP, you may want to consider taking out additional car insurance. Here are some reasons why it could be savvy to consider higher levels of cover: 

  • CTP insurance doesn’t cover damage to property, and going out-of-pocket for accidental damage repairs could be expensive.
  • Weather damage from storms, floods, or hail isn’t covered by CTP (or third-party car insurance). And given Australia’s history with extreme weather events, it might be wise to weather-proof your cover!
  • Being a safe driver isn’t enough to prevent the unexpected prang. There’s also the risk of theft or damage due to vandalism or fires.
  • Even if you’re not at fault and your car is damaged in a bingle, there’s a chance that the at-fault driver won’t have car insurance, refuses to cooperate, or drives away without stopping.
