Australia’s love affair with diesel SUVs has been strong for decades. While hybrids and electric vehicles are rising in popularity, diesel still holds a firm position among buyers who demand long-distance efficiency, rugged performance, and unmatched towing strength. From hauling caravans along the Stuart Highway to handling the muddy tracks of the Kimberley, diesel SUVs deliver the kind of durability and range that petrol and hybrid options often can’t match.
This guide explores the top diesel SUVs available in Australia for 2025, breaking down what makes them stand out—whether it’s efficiency, family comfort, or off-road muscle. We’ll also look at buying considerations, the future of diesel technology, and how these vehicles stack up for different Aussie lifestyles.
The Appeal of Diesel SUVs in Australia
Fuel Efficiency and Range
One of the biggest advantages of diesel SUVs is their superior fuel economy compared to petrol counterparts. A modern diesel engine provides more torque at lower revs, which means better mileage when cruising long highways. For Australians who frequently travel across regional areas where fuel stations are sparse, this extended range is invaluable.
Torque and Towing Power
Diesel engines are renowned for torque, making them ideal for towing caravans, boats, or trailers. For many Aussie families who head off on camping trips or caravanning holidays, a diesel SUV is often the most reliable partner.
Durability and Reliability
Diesel powertrains are built tough and designed to handle high loads over long distances. Many fleet operators and outback adventurers prefer diesel SUVs because they’re known to last longer with proper maintenance.
Lower Running Costs in the Long Run
While diesel cars usually cost more upfront, their long-term fuel savings and engine longevity can offset the higher purchase price. In Australia—where road trips are often measured in hundreds, not tens, of kilometres—this adds up significantly.

Modern diesel SUVs are equipped with advanced driver-assistance systems (ADAS), multiple airbags, and crash-avoidance technology. Always check ANCAP ratings before purchase.
Future Proofing
While EVs and hybrids are gaining ground, diesel SUVs are still widely supported across Australia, especially in regional areas. However, buyers should be aware of tightening emissions regulations that could affect resale in the future.
The Future of Diesel SUVs in Australia
While governments globally push toward electrification, Australia’s vast distances and rural reliance on diesel power mean these vehicles will continue to dominate for years. Many manufacturers are improving diesel engines with better emissions controls, mild-hybrid assistance, and efficiency tweaks.
Expect to see diesel SUVs coexist with hybrids and EVs, particularly in the heavy-duty and long-distance travel segments. For Australians who love exploring, camping, and towing, diesel SUVs are unlikely to disappear anytime soon.
