What a trailer costs to own around Canberra
Not the purchase price: the running cost. Registration on both sides of the border, injury insurance, optional cover, wear parts, storage, and what letting the rego slide costs. Every figure has a named source; anything without one is marked as an estimate.
Registration is the only fixed bill
A light box trailer has one bill that arrives whether you use it or not: registration. Everything else is optional (insurance, paid storage) or depends on how hard the trailer works (bearings, brakes, tyres). For a typical 7x4 the government's share is roughly $85 to $270 a year, depending on which side of the border you live and what the trailer weighs empty.
Access Canberra: fees by tare weight
The ACT fee determination DI2026-146 sets 12 month fees for trailers up to 4.5 tonnes GVM. For registration periods starting on or after 1 September 2026 the lighter bands are:
- Tare 250 kg or less: $104.90
- More than 250 kg and less than 765 kg: $271.50
- 765 kg to less than 976 kg: $348.80
- 976 kg to less than 1,155 kg: $384.30
- 1,155 kg to less than 1,505 kg: $431.30
Bands continue up to $1,587.90 for a tare of 4,325 kg to 4,500 kg. Trailers are excluded from the road rescue fee, and the 2 per cent discount for paying in full is for cars, not trailers. A first ACT registration adds a one-off $71.50.
The cut that was not free rego
Before the 2024 election, ACT Labor promised that single-axle trailers up to 250 kg tare would go from $104 a year to free. What was legislated was a cut of $150, or to $0 where the fee was $150 or less, for registration periods starting from 1 September 2025 to 31 August 2026. That made the smallest band $0 and the next band $121.50 for one year. From 1 September 2026 the ordinary fees above apply again. The process itself is covered at trailer rego in the ACT.
Queanbeyan, Jerrabomberra, Googong: the Transport for NSW bill
NSW splits the bill into an $84 a year registration fee plus motor vehicle tax by tare weight. On the current NSW Government table a privately used trailer up to 254 kg pays $0 tax, 255 kg to 764 kg pays $156, and 765 kg to 970 kg pays $278. Business use is dearer in every band ($137 for the lightest).
Caravans and camper trailers
Privately registered caravans and purpose-built camper trailers from 255 kg to 4.5 tonnes get an automatic 40 per cent cut to the tax, so the 255 kg to 764 kg band drops from $156 to $94. They are also exempt from stamp duty. A plain box trailer gets neither.
Inspections
An unregistered trailer needs a blue slip no more than 42 days old: $42 without brakes, $60 with. From 5 years after the compliance plate date, most trailers need a yearly pink slip to renew: $27 without brakes, $41 with, from 1 July 2026. Trailers under 251 kg tare with no brakes are exempt from the yearly check.
Injury cover comes with the car, damage cover is optional
Neither the ACT nor NSW asks for a separate injury policy on a light trailer. GIO's ACT guidance is that a roadworthy trailer or caravan is covered by the Motor Accident Injuries insurance of the registered vehicle towing it, and Allianz says the same of the tow vehicle's green slip in NSW. That cover is for people hurt in a crash, not the trailer. If it is reversed into at the tip or stolen from the driveway, only an optional trailer policy pays. NRMA and Allianz both sell one. We found no published premium range worth quoting, so get two quotes.
The costs that depend on use
Bearings and brakes
A yearly check is the baseline, as our servicing guide sets out. Parts are cheap: a bearing kit for a common light axle was $26.45 at Bunnings when checked. Labour is the cost and varies by workshop, so the yearly service is an estimate until you ask for a price.
Tyres age out
A box trailer rarely wears its tread off. Tyrepower's guidance is that most trailer and caravan tyres should be replaced after about 5 to 6 years regardless of tread, because the rubber hardens. Read the date code on the sidewall.
Storage
In the driveway it costs nothing but space and weather, which a galvanised trailer handles better than a painted one: see galvanised vs painted. National Storage has outdoor stands at Queanbeyan and Hume; prices are not published online, so ring first.
The cost of an unregistered trailer
In the ACT, a trailer unregistered for more than 12 months needs a roadworthy inspection before Access Canberra will register it again: $51.10 for a trailer up to 4.5 tonnes, plus $21.70 for a re-examination within a month, on the fee schedule current at 1 July 2026, plus a $60.20 re-registration surcharge. Using it on the road unregistered carries a $750 infringement under the Road Transport (Offences) Regulation 2005, and the injury cover above assumes a registered, roadworthy trailer. In NSW the path back is a blue slip at $42 or $60.
A 7x4 box trailer, 12 months, private use
Many 7x4 single-axle box trailers sit near the 250 kg line, and the compliance plate decides the band, so both are shown. Estimates are labelled.
Garaged in the ACT
Registration $104.90 (tare 250 kg or less) or $271.50 (251 kg to 764 kg), from 1 September 2026. Injury cover: $0 extra, carried by the tow vehicle. Inspection: none while the rego is kept current.
Garaged in Queanbeyan
Registration fee $84 plus tax of $0 (up to 254 kg) or $156 (255 kg to 764 kg): $84 or $240. Add a $27 pink slip each year once the trailer is over 5 years old, unless it is under 251 kg with no brakes. Injury cover: $0 extra.
Wear, either side (estimates)
A yearly bearing and brake service: parts under $30, labour by quote. Two tyres about every 5 to 6 years, so set aside a fifth of that price each year. Optional insurance and paid storage: by quote. None of these are fixed, which is the point.
