What Does a Used Prime Mover Cost in Australia? Real Price Ranges by Age, Brand and Configuration
6 min read
A used prime mover in Australia can advertise anywhere from under $20,000 to well over $300,000, and both ends of that range are real trucks doing real work. Based on advertised listings visible on trucksales.com.au, truckdealers.com.au, machines4u.com.au and Gumtree in early August 2026, tidy pre-2010 units commonly ask somewhere in the $15,000 to $60,000 bracket, mid-life trucks from roughly 2010 to 2018 mostly sit between $60,000 and $160,000, and late-model low-kilometre units run from about $150,000 up past $350,000 for a near-new Kenworth. Those are asking prices, not sale prices, and almost all of them are quoted plus GST. What decides where a particular truck lands inside its band is condition, history and configuration, and that is where the money is won or lost.
Why the range is so wide
A prime mover is a chassis, a driveline and a cab, and each of those wears at a different rate depending on the work. A 2015 truck that has done 600,000 km of single-trailer metro work is a different purchase to a 2015 truck with 1.4 million km of B-double linehaul, even though they photograph the same. The market prices the badge and the year first, and the actual mechanical position second, which is exactly the gap a careful buyer exploits and a careless buyer falls into.
One warning on published price guides: the widely quoted ranges you find on directory and lead-generation sites are marketing pages, not market data. Ignore them and look at live listings on the day you are buying.
Price bands by age
These bands describe asking prices observed across trucksales.com.au, truckdealers.com.au, machines4u.com.au and Gumtree in early August 2026. Treat them as a map, not a valuation, and assume plus GST unless the listing says otherwise.
| Age band | Typical asking range (plus GST) | What you are buying |
|---|---|---|
| Pre-2010 | Roughly $15,000 to $60,000 | A truck near or past its first major overhauls. Price the engine, gearbox and diffs as questions, not assets |
| 2010 to 2018 | Roughly $60,000 to $160,000 | The working middle of the market. History and kilometres decide everything here |
| 2019 onward | Roughly $150,000 to $350,000 plus | Late-model fleet turnover and dealer stock. You are paying for remaining component life and emissions-era technology |
Within each band, the spread between the cheapest and dearest comparable truck is routinely $30,000 or more. The sections below are about that spread.
What each brand costs secondhand and why
Brand pricing in the used market reflects perception and parts reality as much as engineering. From the same August 2026 listing scan:
- Kenworth consistently carries the strongest asking prices for its age and kilometres. The market treats the badge as a store of value, helped by a deep parts network and a build-to-order history that suits Australian linehaul. You pay for that reputation going in and you tend to get some of it back going out.
- Volvo and Scania dominate late-model fleet turnover, so supply is deep and pricing is keener, particularly for automated-transmission fleet spec trucks coming off contract. That supply is the private buyer's opportunity.
- Mack sits close behind Kenworth in perception for vocational and roadtrain work, with strong money asked for Superliners and tidy Tridents.
- Western Star trades on driver appeal and tends to hold money in the owner-driver market.
- DAF and the other European marques are usually the cheapest way into a given year and kilometre bracket, which makes them worth a look if your work does not depend on resale.
None of that is a reliability ranking. It is an observation of what sellers ask and what stock exists, and it moves with fleet replacement cycles. For a deeper comparison of how the badges differ in service, see Kenworth vs Volvo vs Scania for Australian work.
Configuration: what adds to the price
- Bogie drive vs single drive. A 6x4 bogie drive suits B-double and heavy combination work and commands more than a comparable 4x2 or 6x2, which are largely confined to metro and single-trailer roles.
- Sleeper vs day cab. A usable sleeper adds meaningful money because it opens up linehaul work. An integrated high-rise sleeper on an American conventional adds the most.
- Engine and rating. Higher horsepower ratings and the engines the market trusts ask more. If the engine choice matters to you, read the comparison of the Cummins X15, Detroit DD15 and Volvo D13 before you shortlist.
- Gearbox. Manual Roadranger trucks and automated manuals each have their own buyer pool, and the wrong one for your driver situation is a discount you will also give back when you sell.
- Hydraulics, PTO and tipper gear already fitted save you a five-figure fitout and price accordingly.
The five things that move a truck $20,000 within its band
- Engine hours versus kilometres. Many listings quote only kilometres. A truck that has idled or done PTO work for thousands of hours has engine wear the odometer never saw. Ask for both numbers, and if the seller cannot produce hours, treat it as unknown history. There is more on reading the two numbers together in how many kilometres is too many.
- Documented service history. A folder of invoices from a known workshop is worth real money. An oral history is worth nothing.
- Emissions system condition. DPF and SCR repairs on emissions-era trucks are expensive enough to swing a deal, and fault history is rarely volunteered.
- Component position. Where the truck sits relative to its next engine overhaul, clutch, brake and tyre spend. A $70,000 truck that needs a rebuild is not a $70,000 truck; see what an engine rebuild actually costs before you convince yourself otherwise.
- Who owned it. One fleet with records beats three owners with none.
Hidden costs that belong in the purchase price
Price the truck as delivered to work, not as advertised. That means adding, where applicable: any deferred engine work, DPF or SCR repairs, a set of drive and steer tyres, fifth wheel wear or rebuild, brake and suspension work found at inspection, registration and stamp duty in your state, and a pre-purchase inspection. On an older truck those items can add up to half the purchase price again. Work through the full used prime mover inspection checklist before money moves, and get a PPSR certificate for a couple of dollars at ppsr.gov.au, because an encumbered truck can be repossessed even after you have paid in full.
Where the private market beats the dealer market
Dealers sell recourse and convenience, and their pricing reflects it. The private market is where the sharp buying is: owner-drivers exiting, small fleets updating, and deceased estate and retirement sales where the truck is priced to move. The trade-off is that you carry the inspection burden yourself. Private listings are also where GST treatment gets loose, so confirm in writing whether the price includes GST and whether the seller is registered, because it changes what the truck actually costs you.
What to do next
Decide your configuration first, set a band from live listings the week you buy, then let condition and history pick the truck inside it. Browse the current prime movers and trucks listed for sale to build your own price sense from real asking prices. And if you have a truck sitting on the fence about replacement, list it free with the engine hours, kilometres and service history stated plainly, because the listings that answer those questions up front are the ones that sell.
