Roadworthy certificates in Australia explained
When you need a roadworthy certificate and what it actually coversA roadworthy certificate (RWC) is a legal document that shows a vehicle is safe to be driven on Australian public roads.
You’ll usually need one when you’re selling a car, re-registering it, or clearing a defect notice. It’s important to remember that a roadworthy doesn’t promise the car is mechanically perfect – it just confirms the essential safety items are up to standard.
Brand-new vehicles that have never been registered in any other country, Australian state or territory do not require an RWC.
Do you need a roadworthy certificate?
A roadworthy certificate (RWC) is issued by an authorised workshop, garage or service station that your state approves. Their job is to check that the vehicle meets minimum safety requirements at the time of inspection.
Different states use different names for the same thing. What is known as a roadworthy certificate in Victoria is a safety certificate in Queensland, a pink slip in NSW, a certificate of inspection in the ACT and a roadworthy inspection in the NT. Some states may update these names in the future.
Not every state requires an RWC when a used car is sold. NSW, Western Australia, South Australia and Tasmania don’t require one at the point of sale.
How roadworthy requirements work in real situations
If you live in a state where RWCs are required, the seller is usually the one who organises and pays for the inspection. Once issued, the certificate is normally valid for 30 days.
A roadworthy inspection focuses only on safety-critical parts of the vehicle. It doesn’t look at things like air-conditioning, power windows, or the general condition of the car. And if something breaks right after the inspection, it’s not covered by the certificate.
Important rules, limits and state differences
- Victoria and Queensland: You must have an RWC when selling a used vehicle
- ACT: Only required once the vehicle is more than six years old
- NT: Required once the vehicle is more than seven years old
- NSW, WA, SA, and Tasmania: No RWC needed when selling a used car
- NSW: Vehicles over five years old need an annual safety check (pink slip) at the time of registration renewal
- RWC validity: Usually 30 days; NSW pink slips last the full 12-month registration period
- Who supplies it: The seller, in most cases
- Cost: In Victoria, a roadworthy certificate inspection typically costs around $200, though the final price depends on any repairs needed
- Some commercial or farm vehicles, including tractors and quad bikes may be exempt depending on their specifications
What does a roadworthy inspection involve
A vehicle being tested for roadworthiness will be assessed on the condition of functional elements including:
- wheels and tyres
- steering, suspension and brakes
- seats and seatbelts
- lights and reflectors
- windscreen, and windows, including front wipers and washers
- vehicle structure including rust
- other safety-related items on the body, chassis or engine
Common questions
For how long is a roadworthy certificate valid?
In Victoria and Queensland, an RWC stays valid for 30 days. Other states have different rules depending on whether an RWC is required at all.
Can you sell a car without a roadworthy?
Yes – in all Australian states and territories except Victoria and Queensland.
When do you actually need one?
In states that require it, an RWC is needed to re-register a used vehicle when ownership changes.
What if the car is unregistered?
An unregistered vehicle can still pass a roadworthy inspection, no matter how old it is. But it must be registered before it can legally be driven on public roads. This requirement is especially pertinent for veteran and vintage vehicles.
What is a defect notice?
If police find safety issues during a roadside check, they can issue a defect notice. The car becomes illegal to drive until the vehicle is fixed.
Costs, fines or penalties
Driving a vehicle that doesn’t meet safety standards can lead to fines of more than $1000, loss of demerit points, licence suspension or even vehicle impoundment.
In Victoria, driving an unregistered four-wheel passenger vehicle attracts a $1018 fine.
