What you need to do to register a car in Western Australia
Car registration in Western Australia is handled by the Department of Transport. You must register your vehicle before you drive it on public roads, and you'll need to renew that registration annually. The process involves providing proof of ownership, proof of identity, and proof that your car has passed a roadworthiness inspection — though new cars are exempt from this inspection for their first registration.
Registration is not optional and not free. The cost varies depending on your vehicle's tare weight (the weight of the car itself, not including cargo), its age, and whether you're registering it for the full year or a shorter period. You can register online, by mail, or in person at a Service WA centre.
Key Takeaways

- You'll need proof of ownership (the certificate of title or bill of sale), proof of identity, and proof of address to complete registration.
- The Department of Transport handles all registrations in Western Australia, and you can complete the process online, by post, or at a Service WA centre.
Getting a roadworthiness inspection before you register
A roadworthiness inspection — commonly called a pink slip in Western Australia — checks that your car meets safety and environmental standards. You'll need one before you can register a used vehicle, unless it's a new car being registered for the first time or you're renewing an existing registration for a car you already own.
Any licensed mechanic or inspection station can perform this inspection. The inspection covers brakes, lights, wipers, tyres, steering, suspension, and emissions. Once the inspection passes, the mechanic will issue you a pink slip certificate, which is valid for a set period. You then use this certificate when you register the vehicle.
If your car fails the inspection, you'll need to have the problems fixed and get a new inspection before you can proceed with registration. Keep the pink slip with you — you'll need to provide the inspection number and date when you register.
Documents you'll need to have ready
Before you start the registration process, gather these documents: proof of ownership (either the certificate of title from the previous owner or a bill of sale if you've just bought the car), your proof of identity (driver's licence, passport, or other government-issued ID), and proof of your current address (a recent utility bill, rental agreement, or bank statement).
If you're registering a used car, you'll also need the pink slip certificate from your roadworthiness inspection. If the car is financed, you may need a letter from your lender confirming they hold the security interest. Some lenders require their name to appear on the registration.
If you're registering the car in a business name rather than your own name, you'll need to provide the business registration details and proof of your authority to register vehicles on behalf of that business.
How to register online through the Department of Transport
The Department of Transport's online registration system is the fastest option if you have all your documents ready. Go to the Department of Transport website and select the vehicle registration option. You'll enter your vehicle's details — make, model, year, engine number, and chassis number — along with your personal information and proof of ownership details.
You'll upload scans or photos of your documents: proof of ownership, proof of identity, proof of address, and your pink slip certificate (if registering a used car). The system will calculate your registration fee based on your vehicle's tare weight. You can pay by credit card or debit card.
After you submit, the Department of Transport will review your process. If everything is correct, you'll receive your registration certificate by post within a few weeks. You can print a temporary registration document when ready after payment, which you can use while you wait for the official certificate to arrive.
Registering by post or at a Service WA centre
If you prefer not to register online, you can complete a registration form by hand and mail it to the Department of Transport with photocopies of your documents and a cheque or money order for the registration fee. The address for posting is on the Department of Transport website. This method takes longer — typically four to six weeks — because your process must be processed manually.
You can also visit a Service WA centre in person. Bring your original documents (not photocopies) and the completed registration form. Staff will check your documents, calculate your fee, and process your registration on the spot. You'll receive a temporary registration document when ready and your official certificate by post within a few weeks.
Service WA centres are located throughout Western Australia. You can find the nearest one on the Service WA website. Some centres require you to book an appointment in advance, so check before you visit.
Understanding registration fees and renewal
Registration fees in Western Australia are based on your vehicle's tare weight. A lighter car will cost less to register than a heavier one. The Department of Transport publishes a fee schedule on its website showing the cost for each weight bracket. You can look up your vehicle's tare weight in your owner's manual or by contacting the manufacturer.
Registration is valid for 12 months from the date it's issued. You can also register for shorter periods — three months or six months — if you prefer, though the per-month cost is higher. When your registration is about to expire, the Department of Transport will send you a renewal notice. You can renew online, by post, or at a Service WA centre using the same process as initial registration.
If you let your registration lapse, you cannot drive the vehicle on public roads. If you're stopped by police, you face a fine. To get back on the road, you'll need to renew your registration and may need a new roadworthiness inspection if too much time has passed.
What happens if your process is rejected
The Department of Transport may reject your process if your documents are incomplete, if the information doesn't match across documents, or if there's a problem with the vehicle's title. If this happens, they'll send you a letter explaining what's missing or incorrect.
Common reasons for rejection include a pink slip that's expired, proof of identity that's out of date, or a mismatch between the vehicle identification number on your documents and the number on the car itself. You'll have the chance to provide corrected documents or additional information. Once you've resolved the issue, you can resubmit your process.
If there's a dispute over ownership — for example, if the previous owner's name is still on the title — you may need to contact the Department of Transport directly to sort it out before you can register the vehicle.
Frequently Asked Questions
Do I need a roadworthiness inspection if I'm registering a brand new car?
No. New cars are exempt from the roadworthiness inspection requirement for their first registration. You'll still need proof of ownership (the manufacturer's certificate of title or bill of sale), proof of identity, and proof of address. After that first registration expires and you renew, you'll need a pink slip for subsequent renewals.
How long does it take to get my registration certificate after I explore?
If you register online or in person at a Service WA centre, you'll receive a temporary registration document when ready that you can use to drive. Your official registration certificate arrives by post within two to four weeks. If you register by post, the entire process takes four to six weeks.
What if I move house after I register my car?
You should notify the Department of Transport of your address change. You can do this online through the Department of Transport website or by contacting a Service WA centre. Your registration itself doesn't need to be updated, but your records should reflect your current address.
Can I register a car that's still being paid off?
Yes, but your lender may require their name to appear on the registration as the security holder. Check with your lender before you register — they'll tell you what documentation they need and whether they need to be listed. Some lenders provide a letter confirming they hold the security interest, which you'll include with your process.
What if my car fails the roadworthiness inspection?
You'll need to have the failed items repaired by a mechanic, then get a new inspection. Once it passes, you'll receive a new pink slip certificate. You can then proceed with registration. There's no limit to how many times you can get inspected — you just need one passing certificate to register.
