Buying an excavator in Queensland means checking four things before you pay: legal towing, wet-season set-up, fire ant cleaning and a competent operator. No licence is needed to dig with an excavator in Queensland. WorkSafe Queensland does recommend fully automatic quick hitches after a serious injury on a construction site.
Choosing the excavator size for Queensland jobs
A 1-2 t mini excavator handles most South East Queensland backyards, landscaping, irrigation and cable trenches, and it travels behind a ute. A 5-6 t machine suits house sites, farm dams and drains on cane and cattle properties, and bigger stormwater jobs. Choose the smallest machine that reaches your deepest trench with some margin.
| Model | Operating weight | Dig depth | Typical Queensland work |
|---|---|---|---|
| Yuchai E12 and YC10 | 1,000 kg | About 1.4-1.5 m | Backyard landscaping, irrigation, cable trenches, post holes |
| Yuchai U18 | 1,880 kg | 2,295 mm | Footings, drainage, pool and garden jobs, small farm work |
| Yuchai YC60 | 5,700 kg | 3,720 mm | House sites, farm dams and drains, larger stormwater work |
Measure gates and paths before you buy, because the U18 narrows to 1,080 mm with its tracks retracted while the YC60 is 1,920 mm wide. The full list of what to compare, from tail swing to auxiliary hydraulics, is in how to choose an excavator.
Towing and moving an excavator in Queensland
Towing an excavator in Queensland is the driver's responsibility, and the loaded trailer must stay within every rating that applies. The limit is the lowest of the ute's towing capacity, its gross combination mass (GCM), the towbar and towball ratings, and the ATM on the trailer's plate. If you're unsure of the loaded weight, check it at a public weighbridge.
In practice, the 1 t E12 and YC10 and the 1.88 t U18 suit a ute rated to tow 3,500 kg with a braked plant trailer, once buckets, fuel and chains are added. The 5.7 t YC60 needs a truck, tag trailer or float.
- Trailer brakes: needed over 750 kg gross trailer mass. Up to 2 t, override brakes are allowed
- Over 2 t: brakes on all wheels, which in practice means electric brakes with an in-cab controller, plus a breakaway system that holds the brakes on for at least 15 minutes
- Load restraint: rated chains or straps to the trailer's tie-down points, with the bucket and blade lowered and loose attachments secured
A tracked excavator can't be registered to drive freely on Queensland roads. Conditional registration for tracked and rubber-track excavators is limited access only, for construction or maintenance work, so most owners move the machine between jobs on a trailer or float.
Fire ants and cleaning machines in South East Queensland
Fire ant biosecurity zones cover parts of Brisbane, Logan, the Gold Coast and surrounding council areas. Soil stuck to an excavator, its buckets and its trailer can carry fire ants, and everyone has a general biosecurity obligation not to spread them. Clean soil and organic matter off the machine before moving between sites, and check the fire ant zone rules before moving soil or equipment.
Setting up an excavator for the wet season
Queensland's wet season packs mud and clay into an excavator's undercarriage, and that mud wears rollers, sprockets and rubber tracks fast. Clean the tracks at the end of each wet day, check track tension, and grease pins and bushes more often when the machine works in water. Park on firm, dry ground so the tracks don't sit in mud between jobs.
For hot, humid days, a canopy with good shade or a cab with air conditioning makes long shifts easier. Keep the radiator and oil cooler clear of grass seed and dust, and watch for rust on the trailer and tie-down points after work near the coast.
Do you need an excavator licence in QLD?
No high risk work licence is needed to operate an excavator in Queensland, and the old excavator certificate was discontinued. The business running the job must still make sure operators are trained and competent, and keep evidence of it. Many sites ask for the national unit RIIMPO320 (Conduct civil construction excavator operations), plus a White Card for construction work.
Queensland's WHS rules also set duties for anyone controlling powered mobile plant. The machine needs suitable operator protection, such as a ROPS or FOPS canopy or cab with a seatbelt. Nobody may ride on it, and it must not collide with people or other plant. If the excavator will work in a quarry, note that Queensland treats a quarry as a mine, and each site sets its own entry rules for plant.
Quick hitches: what WorkSafe Queensland recommends
WorkSafe Queensland recommends fully automatic quick hitches that don't rely on the operator fitting a safety pin. The advice followed a November 2022 incident in which a bucket came off a quick hitch and seriously injured a worker. The WorkSafe Queensland incident alert sets out the controls. Where a hitch isn't fully automatic, always fit the safety pin.
Ask the supplier for the hitch's compliance certificate. The current Australian Standard for quick couplers is AS 13031:2023, which replaced AS 4772-2008, although some Queensland guidance still refers to the older standard. Many principal contractors set stricter hitch rules, so check the site's requirements too.
Before you dig in Queensland
Before any digging in Queensland, lodge a free request with Before You Dig Australia for plans of underground pipes and cables. The person in control of a workplace must take all reasonable steps to get current information on underground services before excavation starts. Plans are a guide, so locate services on site, and watch for overhead powerlines when you load or unload the machine.
Prices and buying a used excavator in Queensland
New value-brand mini excavators of 1.5-2 t were advertised in Queensland from about $18,000 to $33,000 in October 2026, while Japanese-brand dealers mostly quote on request. Some listings show GST and some don't, so confirm whether the price includes GST, buckets, a trailer and delivery.
For a used machine, check the hours against wear on the pedals, seat and tracks, look for leaks at the final drives and check pin and slew ring play. Search the serial number on the Personal Property Securities Register (PPSR) before paying, which costs $2 online. New and used ranges for every size are in excavator prices by size.
Buying an excavator from Meadowbrook
DJJ Equipment's Brisbane branch is at Meadowbrook, near the M1 and the Logan Motorway. It sells the Yuchai range and covers Brisbane, Logan, the Gold Coast and the rest of South East Queensland. Delivery further afield is quoted per job. The team can match a machine, buckets, an auger or a hydraulic breaker to your jobs and the ute you tow with.
They even changed the seat position for me & sourced the trailer with the right weight for my ute. I am extremely happy with my purchase of the U18 excavator & trailer.

That story comes from a public Google review, where you can read the full Google reviews of the Brisbane branch.
On warranty, the E12 carries 1 year or 1,000 hours, and the YC10, U18 and YC60 carry 2 years or 2,000 hours. Common wear parts such as filters, bucket teeth and track parts are kept at the branch.
Match the machine to your ute's towing limits, clean it between sites, use a fully automatic hitch and lodge a Before You Dig request before every job. DJJ sells Yuchai mini excavators from Meadowbrook. Call 1800 355 388 with your jobs and your tow vehicle.
