Buying a car can be an exciting experience, but when it comes to purchasing a vehicle from interstate, things can get a little more complicated. Not only do you have to consider the logistics of getting the car home, but there’s also the matter of paperwork, registration, and compliance to ensure everything is above board.
If you’re considering buying a vehicle—whether it’s a car, motorhome, caravan, RV, or campervan—from outside your state, it’s important to understand what documents you’ll need, what rules apply, and how to handle the administrative process correctly. Getting this right can save you from legal headaches, unexpected costs, and a lot of stress down the line.
In this guide, we’ll break down the paperwork required when buying a car interstate in Australia, explain the key differences between states, and provide practical tips to make the process smooth and stress-free.
Why Buy a Car Out of State?
Many Australians choose to purchase a vehicle interstate for several reasons:
- Better deals or availability: The specific model you want may be cheaper or only available in another state.
- Unique vehicles: Classic cars, imported vehicles, or custom builds are sometimes only listed interstate.
- Wider selection: Interstate markets, especially in major cities like Sydney, Melbourne, or Brisbane, often have a greater range of cars to choose from.
- Specialised vehicles: Motorhomes, caravans, and campervans are sometimes more available in certain states due to travel and tourism demand.
While these advantages are appealing, they come with the added responsibility of sorting out paperwork and transportation.
Key Paperwork When Buying Interstate
Here are the main documents and requirements you’ll need to take care of when buying a vehicle from another state in Australia.
1. Proof of Ownership (Receipt or Invoice)
The first and most basic document is proof of purchase. Whether you’re buying from a dealership or a private seller, you’ll need a receipt or invoice showing:
- The names of the buyer and seller
- Vehicle details (make, model, VIN, engine number, registration number)
- Sale price and date of purchase
- Signatures from both parties
This document protects you legally and ensures that the ownership transfer is recorded properly.
2. Registration Papers
Each state issues its own registration certificates. When buying a car interstate, you should ensure that:
- The seller provides the current registration papers.
- The registration matches the vehicle details (check the VIN and engine number).
- If the registration is still valid, you may be able to transfer it into your name (although some states require a new registration in your home state).
In some cases, it’s simpler to purchase the car unregistered and organise registration in your own state. This may avoid the hassle of transferring registration across borders.
3. Roadworthy or Safety Certificate
Each state in Australia has its own requirements for roadworthiness certification:
- NSW: Requires a ‘pink slip’ (safety check) before registration transfer.
- VIC: A Roadworthy Certificate (RWC) is compulsory when selling a registered vehicle.
- QLD: A Safety Certificate must be provided by the seller for registered vehicles.
- SA, WA, TAS, NT, ACT: Requirements vary but generally roadworthy checks are required for registration or transfer.
If the seller provides you with a valid certificate from their state, you may still need a new certificate in your home state to finalise the registration. Always check the requirements with your state’s transport authority before committing to the purchase.
4. Vehicle Transfer Forms
When transferring ownership, you’ll need to lodge the appropriate transfer forms. Both the buyer and seller typically need to complete sections of the form. These are usually available online from your state’s transport authority.
For example:
- VIC: Notice of Disposal (by seller) and Transfer of Registration (by buyer).
- NSW: Notice of Disposal and Application for Transfer.
- QLD: Transfer of Vehicle Registration Application.
If the vehicle is staying registered in the seller’s state temporarily, you may need to complete the paperwork there before registering in your own state.
5. Identification Documents
As the buyer, you’ll need to provide proof of identity when registering the vehicle in your state. Typically, this includes:
- A driver’s licence (with current residential address)
- Additional documents if requested (such as utility bills or proof of residence)
If you’re registering under a company name, you may need to provide your ABN and business documents.
6. Insurance Documents
Car insurance is another important part of the paperwork. In Australia, you’ll need:
- Compulsory Third Party (CTP) insurance: Mandatory in all states, but included in registration in some jurisdictions (like NSW and QLD).
- Optional insurance: Comprehensive or third-party property insurance should also be arranged before you drive your new car home.
Make sure your insurance starts from the day of purchase.
7. Import Approval (If Applicable)
If you’re buying an imported vehicle that has been brought into Australia, you’ll need to check that it has the correct Vehicle Import Approval from the federal Department of Infrastructure. Without this, you won’t be able to legally register the car in any state.
Steps to Register an Interstate Vehicle in Your State
After collecting all the necessary paperwork, here’s the general process to register your new car in your home state:
- Obtain a roadworthy certificate in your state (even if you already have one from the seller’s state).
- Complete the registration application at your state’s transport authority.
- Provide proof of purchase and identity documents.
- Pay stamp duty and registration fees.
- Receive new licence plates (unless transferring existing plates is allowed).
Each state has slight variations, so it’s always best to check the official website of your state’s Department of Transport or Roads authority.
Common Pitfalls to Avoid
When buying interstate, many buyers overlook important details. Here are some common mistakes to watch out for:
- Not checking the PPSR (Personal Property Securities Register): This ensures the car isn’t under finance or stolen.
- Assuming the registration transfer is automatic: You usually need to actively apply and pay fees.
- Not budgeting for stamp duty differences: Each state charges different rates.
- Overlooking transport costs: If you can’t drive the vehicle back yourself, towing or freight can be an added expense.
- Failing to inspect the car: Photos can be misleading—if possible, inspect the vehicle or hire a professional inspection service before buying.
Special Considerations for Motorhomes, Caravans, RVs, and Campervans
Larger vehicles like motorhomes and caravans often involve more complex paperwork. In addition to the standard documents, you may need:
- Weighbridge certificate: To confirm the vehicle’s mass, especially if it’s been modified.
- Gas and electrical certificates: For caravans and RVs with built-in appliances.
- Modification plate or compliance plate: If the vehicle has been altered from its original design.
These documents are essential to meet safety and compliance requirements before registration.
Transporting Your Interstate Purchase
Once the paperwork is in order, you’ll need to consider how to get your new vehicle home. If it’s a standard car in good condition, you may be able to drive it yourself with temporary registration or an unregistered vehicle permit.
However, for larger vehicles like motorhomes, caravans, RVs, and campervans—or if the car is unregistered or not roadworthy—professional transport is often the safest and most practical option.
