How to check car insurance
There are 2 simple ways to check your car insurance: running a rego check and looking at your insurance policy.

You can confirm whether your car is insured online by visiting the website of your state or territory's vehicle registration department. Here's a list of the relevant websites:
If your car is registered in NSW, you can look up the CTP insurer for your vehicle by using Service NSW to check registration. For all other states and territories, CTP insurance (also known as 'Green Slip insurance or motor accident insurance (MAI)') is included with your registration. You can still check your car's CTP and MAI with your state or territory's car registration site.
Regardless of which state or territory you live in, you must buy CTP insurance when you register your vehicle. It is a legal requirement.
To check who your car is insured with, you can use the 'check registration' site of the state or territory your car is registered in. Registration checks are free and they include:
If you don't have CTP insurance or it is up for renewal in the next three months, you can use the Green Slip Check in NSW to get a CTP Green Slip quote comparison from all insurers. You'll need your driver's licence number or billing number and the vehicle's plate number to receive quotes.
While there are handy government websites to check who your CTP or MAI insurer is, the same doesn't exist for comprehensive car insurance. If you're not sure who you're insured with, you'll have to find any policy documents or communications you've had with your insurer.
A good place to start is to check your email inbox and see if you've received any letters of renewal or a policy certificate. Most insurers will send you confirmation and essential policy details by email, and you should be able to find these by searching your registration number. If you can't locate your details through email, your insurer may have sent you hard copies of your policy details. Take a look at where you keep all your important paperwork, your details may be easier to locate than you think.
If you're still unable to find your comprehensive car insurance documents, it might be helpful to contact your bank or check your statements. You'll likely have a standing order or direct debit arrangement set up with your bank account or credit card. These transactions will help you figure out who you've insured your car with.
To check if a car is registered, all you need to do is go to the check registration site of your state or territory:
In most cases, you can also call if you can't check your car registration online.

How can I find out who my car is insured with (comprehensive insurance)
Hi Max,
Unfortunately there is no national database of comprehensive policies, so the only way to know who your car is insured with is to locate a copy of your policy. You might be able to check your emails for the policy?
Hope this helps.
