Grain trailers in Australia: what they cost and how to buy

Updated 4 November 2026

A grain trailer in Australia costs roughly A$3,800 to A$14,800 for a tandem trailer on a stock, flat-top or tipper body, and A$20,700 to A$31,400 for an imported grain semi-trailer. These are approximate prices, according to sellers' websites, November 2026. The quickest way to current prices is a request on BlaBlaPrice.

Local rules to check first

A trailer's aggregate trailer mass (ATM) decides which rules apply. Trailers with an ATM of 4.5 tonnes or less are expected to meet the Australian Design Rules, according to the federal Vehicle Standards Bulletin, so ask the seller for the compliance papers and the ATM plate. Heavy trailers fall under the Heavy Vehicle National Law, which names dog, pig and semi-trailers as the three main types. In Victoria, certain agricultural trailers are exempt from registration, so check your state's rules before you buy a farm trailer. Under the Australian Consumer Law a seller cannot exclude the guarantees, so a major failure gets a replacement or refund.

Season and the weather

November is late spring. Summer runs from December to February and winter from June to August, so a trailer bought now is ready for the hot months, when tyres and wheel bearings work hardest in the heat. Check both before a long haul between Sydney, Melbourne, Brisbane, Perth and Adelaide, and book a service in good time.

How trailers are bought here

Listings give size as length by width, such as 10x6, and weight as ATM in kilograms. Ask for the unladen weight too, so you can work out the payload you can really carry. Ask whether the quoted price includes delivery to your city, and whether the trailer is new or used. Delivery between Sydney, Melbourne, Brisbane, Perth and Adelaide is a real cost, so compare delivered prices, not list prices.

What to put in your request

Name the towing vehicle, the body volume you need, the payload, the number of axles and how the trailer unloads, for example by side dump or hydraulic tipper. Add the make and year you prefer, the condition you accept, your budget and your city. Those details decide whether the first offers fit your work.
