Trailer rego in the ACT
What a trailer needs before Access Canberra will register it, when an inspection is required, what the fee cut actually was, and how to check a rego before you buy. Queanbeyan readers: the NSW rules are at the end.
Every trailer on the road
Access Canberra requires light trailers (under 4.5 tonnes gross vehicle mass) and caravans to be registered to be used on the road. There is no small-trailer exemption in the ACT. Heavy trailers over 4.5 tonnes go through a separate process and are not covered here.
When Access Canberra wants to see the trailer
Brand new from a dealer or builder
No Vehicle Identity Check is needed. Access Canberra does say a brand new trailer or caravan needs an ACT roadworthy inspection before it is registered at a Service Centre. A new trailer bought interstate is treated the same way: bring it home on an unregistered vehicle permit, pass the inspection, register it.
Newly built trailers and the RAV
Access Canberra no longer issues VINs for new trailers. A newly built trailer has to carry a VIN and compliance plate from a maker with Australian Government (ROVER) approval, and be listed on the Register of Approved Vehicles, before the ACT will register it. A proper builder does this as part of the build and hands you the paperwork. If a seller cannot show you the RAV entry, you are looking at a trailer that may never be registrable.
Used, last registered in the ACT
An inspection is only needed if the trailer is more than 6 years old (from the month and year of manufacture), has been unregistered for more than 12 months, or had its registration cancelled. Otherwise it is a transfer, not an inspection.
Used, last registered interstate
An inspection is needed regardless of age. A used trailer may also need a Vehicle Identity Check.
Home built
The long road: ROVER approval, a VIN marked on the compliance plate, a RAV entry, a weighbridge ticket for the empty trailer showing the VIN and tare, an inspection at the Hume station or an authorised inspection station, then the Service Centre. Inspection fees apply at each step.
The fee cut, and why rego is not free
Before the 2024 ACT election, Labor promised that the smallest single-axle trailers (tare up to 250 kg) would go from $104 a year to free. What was introduced was smaller and temporary: a cut of up to $150 (to $0 where the fee was $150 or less) for light trailer registration periods starting between 1 September 2025 and 31 August 2026, applied automatically at renewal. That year has ended. From September 2026 the ordinary fees apply again.
Fees are set by weight, so a heavier trailer costs more every year. Under the ACT fee determination that took effect on 1 July 2026, the lightest band (tare 250 kg or less) is $104.90 a year and the next band (251 kg to 764 kg, which covers most 6x4 and 7x4 box trailers) is $271.50. The full bands are in what a trailer costs to own. That is one reason not to size up "just in case": see choosing a trailer. The amount for your trailer is on the renewal notice, and ACT rego can be renewed online at any hour with a card.
Checking a trailer's rego
Search the numberplate through Access Canberra's registration check. Then look at the trailer itself: the plate on the drawbar should match the paperwork, the compliance plate should be present and readable, and the VIN on it should match both. A trailer with no identifying details can be genuinely hard to register, and a trailer unregistered for more than 12 months will need an inspection before it is yours to tow. Our buying a used trailer notes cover the chassis and coupling checks.
Queanbeyan, Jerrabomberra, Googong, Bungendore: the NSW rules
A trailer is registered where it is garaged, so most of our neighbours deal with Service NSW. The rules are different enough to matter.
Registering an unregistered trailer
Lodge the registration form at a Service NSW Centre with an original blue slip (an Authorised Unregistered Vehicle Inspection) issued no more than 42 days earlier. Trailers over 2 tonnes ATM need a heavy vehicle inspection report instead. A weighbridge ticket is needed if the tare cannot be confirmed from a specification sheet, if the trailer was imported, or if it has had a major change.
Renewing: the pink slip
Once a trailer is more than 5 years old, counted from the month and year on its compliance plate, NSW needs a yearly safety check (pink slip) from an Authorised Inspection Scheme station to renew. The report is valid for 6 months. Trailers with a tare under 251 kg and no brakes, and caravans under 411 kg tare, are exempt from the yearly check. The renewal notice says whether one is due.
Camper trailers and caravans
NSW gives caravans and camper trailers from 255 kg to 4.5 tonnes a 40 per cent reduction on the vehicle tax, and exempts them from stamp duty.
