Choosing third party property damage vs. comprehensive car insurance

18 October 2019

There are two main car insurance options worth considering: comprehensive car insurance and third party property insurance. Each has different levels of cover, but how do you know which is best for your situation?

Luckily, that’s where we come in.

What is the difference between comprehensive and third party insurance?

Comprehensive car insurance generally lives up to its name. It’ll cover you for a wide range of damage caused by an insured event like an accident, theft and weather events (think hail, fire and storms including cyclones). It also has your back if you cause any damage to someone else’s car and property. Third party insurance, on the other hand, only covers damage to another person’s vehicle and property.

An important thing to note: Compulsory Third Party (CTP) Insurance, or Green Slip, isn’t the same thing as third party car insurance. CTP covers your liability, and the liability of anyone else who drives your vehicle, for injuries caused to others in a motor accident. It doesn’t the cover the cost of damage to yours or anyone else’s car or property. When you drive in Australia, you need to have CTP insurance before you can register your car. In most places it’s rolled into your registration, but in NSW you need to purchase it separately.

Finding the right car insurance for you

Before you start shopping around for car insurance, it’s important to assess your car insurance needs so you don’t end up paying more than you should. To do this, you might like to consider:

  • Calculating the value of your car against your insurance premium and excess. Then decide which kind of car insurance is likely to give you the best combination of cover and value.
  • Whether you’ll require cover for fire and theft.
  • If you can afford the cost of repairing someone else’s vehicle. If the answer is no, some form of car insurance may be useful for your situation. Depending on the amount of damage and the type of car, repair costs could set you back thousands of dollars1.

We’ve compared the features of comprehensive and third party insurance, so you can see at a glance which option might be right for you.

Comprehensive car insurance

Though comprehensive car insurance may cost you more than third party property damage, it offers an extensive range of features and benefits. These include cover for:

  • ​the value of your car (amount covered) or your car’s market value (if you have chosen this option). If the market value option has been chosen it will be listed on your Certificate of Insurance,
  • damage caused to your car, regardless of fault,
  • damage that you’ve caused to someone else’s property or vehicle, and
  • theft and malicious damage.

Make sure you read the product disclosure statement prior to purchase. Features of comprehensive car insurance that are standard with some providers may not be with others. Check things like your entitlement to a hire vehicle while your car’s in for repair or whether there’s an option to include roadside assistance on your comprehensive cover.

Third party property car insurance

Third party property car insurance, sometimes called Third Party Property Damage, covers damage to other people’s vehicles and property. If your car is damaged in the same event, and the accident is your fault, it won’t be covered for repairs.

So, if the value of your car isn’t huge, third party car insurance may be enough cover for you. But if you think you’ll need to cover your vehicle, comprehensive car insurance might be worth considering.

Third party property car insurance with cover for fire and theft

This type of car insurance is third party property car insurance; however, you can choose to include cover for fire and theft. This means your car is covered if it’s stolen, or damaged by fire or attempted theft.
