CTP Insurance in Australia: What you need to know

Key points

• CTP Insurance is mandatory and covers injury, not vehicle damage.
• Compare providers in eligible states to save money.
• CTP rules, claims, and premiums vary by state and vehicle type.

What is CTP Insurance?

Compulsory Third Party (CTP) Insurance is a legal requirement for all registered vehicles in Australia. It covers compensation costs if you injure or kill someone in a motor vehicle accident but doesn’t cover vehicle or property damage. For that, you need comprehensive or third-party property insurance.

Also known as Green Slip in NSW, CTP is your legal safety net and helps protect you from financial fallout. However, not all CTP policies are created equal – comparing them could save you more than money.

How CTP Insurance works in each state and territory

CTP vs. other car insurances

Green Slip compare: How to find the best CTP policy

In states like NSW, you can compare CTP Green Slip providers based on a range of search criteria, including:

• Price (varies by factors such as age, location, driving history)
• Claims process 
• Customer satisfaction 
• Discounts (some insurers offer bundles with other policies) 

Use tools like the SIRA Green Slip comparison tool to compare quotes and performance.

What happens if you don’t have CTP Insurance?

Driving without CTP Insurance is illegal and could result in:

• Fines and penalties 
• Vehicle registration cancellation 
• No cover if you injure someone 

Important: Even with CTP, if you’re found to be driving recklessly or under the influence, you could still be sued personally – especially if your state doesn’t offer at-fault driver protection.

Roundup: Getting the most out of your CTP Insurance

Follow these practical tips to help you better understand how to manage your CTP Insurance:

1. CTP doesn’t cover your car 

CTP only covers injuries to other people — not damage to your vehicle or property. For that, you’ll need third-party property or comprehensive insurance.

2. You can still be sued 

Even with CTP, if you're found to be driving recklessly or under the influence, you could still face legal action. Some states offer limited protection for at-fault drivers, but not all.

3. CTP premiums vary by risk factors 

Your premium is influenced by your age, gender, driving history, vehicle type, and where you live. Safer drivers and less risky vehicles often pay less.

4. You can switch CTP providers (in some states) 

In NSW, QLD, and SA, you can choose your CTP insurer. In other states, it’s bundled with your registration and not open to choice.

5. CTP claims process varies 

Each state/territory and insurer has its own claims process. Some offer online claims, while others require forms or phone calls. Visit your state/territory’s CTP authority website for step-by-step instructions.

6. CTP discounts or bundles 

Some insurers offer discounts if you bundle CTP with other policies, like comprehensive car or home insurance. It’s worth asking when comparing quotes.

7. CTP for motorcycles and commercial vehicles 

Premiums and coverage rules differ for motorcycles, taxis, rideshare vehicles, and commercial fleets. Make sure you’re covered correctly for your vehicle type. Check with your state/territory authority for tailored policies.

Conclusion

Whether you're a new driver or just due for rego renewal, understanding CTP Insurance is essential for staying safe – and legal – on Australian roads. While it’s mandatory, that doesn’t mean it’s one-size-fits-all. From comparing Green Slip providers to knowing what’s covered (and what’s not), a little knowledge can go a long way. Take the time to compare, bundle smartly, and check your state/territory’s rules. Your wallet and peace of mind will thank you.
