Frequently Asked Questions

Is CTP the same as car insurance?

No. CTP covers injuries to other people only. It doesn't cover damage to your car or their property. You need separate car insurance (comprehensive or third party property) for that.

Can I drive without CTP?

No. CTP is legally required to register a vehicle in every state. Driving unregistered means driving without CTP — which is illegal and financially reckless.

Why is my Green Slip so expensive?

In NSW, Green Slip prices vary by insurer, postcode, age, and vehicle type. Young drivers and drivers in high-claim postcodes pay more. Always compare at greenslips.com.au or the SIRA price check tool.
