Motor graders in Australia are listed from about A$32,700 for a used 140-class machine to around A$57,000 for a used 930-class unit, while a 2023 Komatsu GD655-7 in excellent condition is listed at A$350,000. Price depends on engine hours, blade width and year. The quickest way to current offers is a request on BlaBlaPrice, where sellers reply with their own price and terms.

Warranty and what the law says

Standard warranties on new graders run for 12 to 24 months or 2,000 to 4,000 engine hours, and extended cover of up to five years is available for an extra cost. Used machines from reputable dealers often carry limited warranties of three to 12 months covering the major components. Whatever the terms, the Australian Consumer Law cannot be excluded: if a major failure happens, you are entitled to a replacement or a refund. Get the warranty in writing and check which hours it counts.

Season and timing

Summer runs December–February and winter June–August, so October is the spring lead-up to the hot months. Plan a purchase or hire for the season your project runs in. A machine serviced before a long summer job avoids delays, and it is worth asking the seller when the last major service was done.

How it is quoted and delivered

Listings state blade width in metres or centimetres, power in horsepower or kilowatts, and the engine hours on the meter. A grader is heavy to move, so ask whether the price includes transport to your site in Sydney, Melbourne, Brisbane, Perth or Adelaide. Transport is a separate cost to plan for, and the seller should say who arranges the low-loader.

What to put in your request

State whether you want to buy or lease, the scope of work (road maintenance, earthworks, gravel roads), the condition you accept, the model and power you need, the year and engine hours, your city, the lease term and your budget. A clear list lets sellers quote one machine that fits, rather than send a long list of options.

BlaBlaPrice is free for buyers. Describe the job in the chat, add a photo if it helps, and the AI asks for missing details, looks through sellers' websites and price lists in Australia, and shows the prices and businesses it found. Sellers registered here reply with their own offer, and your contacts stay hidden until you choose to share them. Related machines are in heavy equipment and excavators.
