What Is CTP Insurance and Do You Actually Need It?

CTP insurance

If you’ve ever registered a car in Australia, you’ve probably heard of Compulsory Third Party (CTP) insurance. But do you really understand what CTP insurance covers and why we all need it?

Car insurance can be a confusing topic, especially when you consider the different types of policies available and the coverage they can provide. In this article, we’ll unpack important information about CTP insurance – also known as Green Slip insurance in NSW – including:

  • W​hat it covers
  • Why it’s mandatory when registering a car in Australia
  • How it differs across the states and territories
  • How it fits in with other ​types of car insurance.

What does CTP insurance cover?

In the event of an accident, CTP insurance helps cover at-fault drivers from compensation claims associated with injuries to other people or fatalities caused by that accident.1

“CTP insurance helps provide coverage for claims made by any passengers, pedestrians and other road users not at fault in a motor vehicle accident,” says Youi’s Head of Product – CTP, Glen Robinson.

“It covers costs such as treatment, care and rehabilitation, and may cover loss of income and damages in some states. In New South Wales, for example, there is also limited coverage for injuries to the driver at fault of the motor vehicle.”

CTP insurance is linked to your vehicle’s registration rather than individual drivers, which means anyone who drives your vehicle is covered by your policy. However, it’s important to note that CTP insurance only covers injuries caused by the accident. It doesn’t cover you for damage to your own vehicle, the third party’s vehicle or other property damaged in a car accident.

Is CTP insurance compulsory?

As the name suggests, CTP insurance is mandatory for all vehicles registered in Australia.2

This means you need CTP insurance to be registered to legally drive on public roads in Australia. In terms of car insurance, CTP insurance is the absolute minimum level of coverage required.

How does CTP insurance work in different states and territories?

Despite the fact that CTP insurance is a requirement in all states and territories, there are slight differences in how each state or territory handles the purchase of CTP and the cost to drivers.

“In some states, your CTP insurance is paid along with your vehicle registration, but in New South Wales your CTP needs to be purchased separately before you can register your vehicle,” explains Robinson.

“CTP insurance is privately underwritten by insurers in New South Wales, South Australia, Queensland and the ACT but in all other states in Australia, CTP insurance is managed by the government.

“Governments will also consider different factors in setting premium levels to ensure future scheme affordability, cover lifetime care benefits for seriously injured road users, and administrative expenses. This can lead to variations in premiums between states.”

Youi CTP is available in New South Wales and South Australia.

CTP insurance NSW: How does it work?

In New South Wales, CTP insurance is also known as a Green Slip, or CTP Green Slip, and must be purchased separately from a choice of insurers, including Youi, prior to registering your vehicle.3

Depending on the age of your vehicle, it might also need a safety check, known as a Pink Slip in NSW, before it can be registered.4

Green Slip premiums can differ based on a range of factors, including driver age, your driving record, your vehicle’s age and your claims history.5

Do I need other types of car insurance on top of CTP insurance?

CTP insurance is the only mandatory car insurance in Australia. However, depending on your personal circumstances, it could be worth considering taking out extra cover, such as Third Party Property Only, Third Party Fire & Theft or Comprehensive Car Insurance, for greater protection on the road.17
