ROVER registration guide for DIY caravan builders

The rules for newly built caravans and trailers changed from 1 July 2023. For a DIY caravan builder, the important point is this: the caravan or trailer generally needs a Commonwealth approval and an entry on the Register of Approved Vehicles (RAV) before your state or territory registration office can register it.

This does not mean DIY caravan building is impossible. It does mean the paperwork moved from the old self-certification style into the Australian Government's ROVER system. Use this page as a plain-English guide only. The official ROVER pages and your state or territory registration authority are the final source for your build.

1. What changed after July 2023?

ROVER stands for ROad VEhicle Regulator. It is the Australian Government online portal used for Road Vehicle Standards approvals.

Under the current low ATM trailer rules, caravans, dog trailers, pig trailers and other trailers with an Aggregate Trailer Mass (ATM) of 4.5 tonnes or less need the correct approval pathway before they are provided to the Australian market or registered for road use.

The old system relied heavily on a trailer identification plate and self-certification against VSB 1. The newer system requires vehicle and compliance information to be listed on the RAV. The RAV entry is what your state or territory registration process will look for before registration can be completed.

2. Which ROVER pathway applies?

For a home-built caravan or camper trailer with an ATM of 4.5 tonnes or less, the pathway will usually be one of these:

Concessional RAV entry approval: generally aimed at manufacturers or importers providing four low ATM trailers or less in a 12-month period. This is the pathway most relevant to a one-off DIY caravan or trailer build.
Vehicle type approval: generally required when a manufacturer or importer provides more than four low ATM trailers to the Australian market in a 12-month period.

If you are building a motorhome, importing a vehicle, modifying an existing registered vehicle, or doing anything outside a normal low ATM trailer build, do not assume this guide covers your case. Start with the official ROVER information and your state registration authority.

3. Before you start the application

The best time to think about registration is before the caravan is finished. ROVER is not just a formality at the end. You need to be able to show that the trailer is designed and built to comply with the applicable national road vehicle standards.

Before applying, gather the practical details of the build:

Make, model or identifying description for the trailer.
ATM, tare mass target and basic dimensions.
Axle, suspension, coupling, tyres, wheels and brake details.
Lighting, reflectors, safety chains and drawbar details.
Evidence that the build complies with VSB 1 Revision 6 and any relevant Australian Design Rules.
Photos, drawings, receipts or component information that support the application.

The more clearly you know what you are building, the easier the application will be. If you are still planning the caravan, work through the design, chassis, suspension, body, plumbing, gas and electrical decisions before relying on a registration path.

4. What happens in ROVER?

To use ROVER, you create an account and start the relevant application in the online portal. The form asks for applicant details, vehicle details, compliance information and declarations. Fees may apply.

For a low ATM trailer concessional RAV entry approval, the official ROVER guide explains what information and documentation must be included. Read that guide before starting the form, because the wording and required evidence can change over time.

During assessment, the department may request more information or clarification. Keep an eye on the application inside ROVER and respond to any requests. Do not assume the caravan can be registered until the approval and RAV entry steps are complete.

5. After ROVER approval

Once the Commonwealth approval process is complete and the caravan is entered on the RAV, the state or territory registration process still needs to be completed. That step is handled by your local registration authority, not CaravansPlus.

Depending on where you are registering the caravan, you may need items such as:

Evidence of the RAV entry.
A VIN or vehicle identification marking completed as instructed.
A weighbridge ticket showing tare weight.
An inspection or roadworthy check.
Receipts, identity documents, forms and registration payment.

State and territory requirements vary, so check the current registration page for your location before booking an inspection or towing the caravan to a registration office.

6. Common traps for DIY builders

Leaving compliance until the end: VSB 1 details such as dimensions, overhang, lights, brakes, coupling, chains, tyres and guards are much easier to solve during the build than after paint and fit-out.
Using old forum advice: A lot changed after July 2023. Check current official pages rather than relying on older self-certification advice.
Confusing ROVER with state registration: ROVER/RAV approval and state registration are linked, but they are not the same step.
Choosing the wrong pathway: A one-off DIY trailer is different to a business building or importing multiple trailers.
Not keeping records: Photos, component information, receipts and build notes can be useful if questions come up during the approval or inspection process.

CaravansPlus cannot complete your ROVER application or register your caravan for you. Use the official ROVER guides and your state or territory registration authority for the current legal process.

Good luck with the build. The process is more formal than it used to be, but the aim is still straightforward: build the caravan so it complies, keep the evidence, get the correct ROVER/RAV approval, then complete the registration step with your state or territory authority.
