The money you pay us toward your Compulsory Third-Party (CTP) insurance policy is called a premium. The amount you pay can change each year and you may wonder why. As a trusted insurer, we want to help you understand your premium. This guide gives you the facts: how your premium works, how we calculate it, and why it can change.

How your premium works

CTP insurance is compulsory in Australia and is needed to register your vehicle. However, each state and territory has its own scheme.

In NSW, CTP insurance is also commonly known as a ‘Green Slip’. It can be bought through Allianz using a number of risk factors to calculate fairly priced premiums as explained below.

In QLD and SA, CTP is paid for as part of the registration process. You can choose Allianz as your CTP insurer when you register your car or renew your registration.

In ACT, CTP is also paid for as part of the vehicle registration process. However, Allianz isn’t currently one of the insurers that can be selected.

In VIC, WA, TAS, and the NT, CTP insurance is government run and arranged through its own distribution network. It’s included in the price you pay each time you register your vehicle.

Limitations and exclusions

Our state-specific CTP insurance products provide different levels of base coverage and each have their own set of limitations and exclusions. These factors can influence how premiums are calculated and what is and isn’t covered under your policy.

Calculating your CTP premium

NSW

Insurance companies determine their own prices for CTP insurance in NSW in a competitive market and use a combination of factors to set premiums, before the addition of government charges and taxes. However, they are regulated by the State Insurance Regulatory Authority (SIRA). SIRA requires that NSW CTP insurers follow the rules and provide fairly priced premiums.

CTP premiums charged by an insurer must be enough to cover the costs of potential future claims as well as their operational costs. When setting the premium for each customer, the insurer will ask questions to determine what the likelihood is of a claim being made. These questions are known as rating factors and your answers will affect the premium you are charged.

When you apply for Allianz NSW CTP Insurance, we’ll ask you specific questions to better understand your risk profile and help ensure that we are offering you a fair price. It’s important that all customers answer them accurately to ensure that the correct premium is paid and there is no impact to their vehicle’s registration.

Details requested include:

  • Your vehicle make and model
  • The age and gender of the youngest licensed drivers
  • The use of the vehicle
  • Your driving history including demerits, licence suspension and at-fault claims
  • What other insurance you have on your vehicle
  • Where the vehicle is garaged
  • Any discounts you’re entitled to will be calculated and included in your base premium, before applying any additional government charges and taxes. Insurers aren’t permitted by law to offer additional discounts that aren’t included in the base premium (including any adjustments for endorsements).

We then add compulsory government charges and taxes to give us the final price.

In short, this is how we work out CTP premiums in NSW:

Allianz (base) premium + Compulsory Government charges = Your NSW CTP insurance premium
QLD & SA

In QLD and SA, the way insurers set pricing works differently. The relevant CTP regulator establishes the pricing framework and approved premium ranges for vehicle classes. Insurers may then set premiums within those approved ranges.

Unlike in NSW, insurers aren’t permitted to use their own rating factors to vary the price that’s charged to different customers.

Premiums can differ depending on whether or not your vehicle is used as part of a GST registered business in all states and territories. In SA, it can also vary depending on where you live. Prices are otherwise the same for all drivers that own the same type of vehicle

As with NSW, government charges are also included in the CTP premium.

Government charges added to your CTP premium

Like other insurers, Allianz must collect certain charges and taxes by law. These can make up a significant portion of your premium. These include:

Fund levy

The Fund Levy is separately applied to CTP premiums in NSW only. It’s a fee set by SIRA that varies based on vehicle type and garaging location. This means some people will pay more and others will pay less towards the Fund Levy. The Fund Levy is regularly reviewed and adjusted by SIRA to reflect the funding that’s needed to cover the services that the Levy is used to pay for from time to time.

The Fund Levy can be used for:

  • Ambulance and initial hospital care
  • Lifetime care for those with a severe injury
  • Preserving funding for future severe injury claims
  • Treatment and care services, provided by SIRA, for people who still need them more than five years after an accident
  • Funding the administrative costs of SIRA.

Your NSW Fund Levy will be separately identified on your invoice.

QLD and SA both have similar levies which are automatically included in the cost of CTP. These are used to fund:

  • State Schemes that provide for the lifetime care of severely injured road users
  • Claims made against unidentified or uninsured vehicles
  • The administrative costs of the CTP Regulator
  • The State transport administrators that support the CTP Schemes.

Goods and Services Tax (GST)

CTP insurance premiums are subject to GST. This means the total CTP premium you pay includes the GST rate set by the Australian Government. Changes in the GST rate affect the total price you pay for CTP.

Stamp duty

Stamp duty is a form of tax imposed by Australian state and territory governments. It applies to many kinds of transactions, including insurance policies. The rate of stamp duty varies between states and territories. The cost of stamp duty is typically factored into CTP premiums. It can differ depending on which state or territory the vehicle is registered in. CTP insurance is exempt from stamp duty in NSW.

Why is CTP Insurance compulsory?

CTP insurance is compulsory. It helps people who are injured or killed in a motor vehicle accident get compensation and support. It also means vehicle owners and drivers aren't left to cover the potentially high costs of causing those injuries.

It's important to know that CTP insurance covers personal injury claims only. It doesn't cover damage to vehicles, property, or losses covered by comprehensive car insurance.

Drivers who don't comply with the policy may be required to repay the costs of any CTP claim arising from an accident they cause.
