Unidan Engineering is a global leader in off-road vehicle solutions, specialising in custom builds, precision-manufactured parts, and servicing—ensuring reliable performance in the most demanding environments.

Designed for swift water rescue, this emergency response vehicle offers high ground clearance, exceptional wading depth, and secure storage for critical gear. Interchangeable bodies allow rapid adaptation to a range of emergency scenarios, improving response times and reducing costs.

To support PNG’s mining sector, Unidan restored five ex-ADF Unimogs for remote, high-risk deployment. Each vehicle features upgraded mechanical systems, custom riot protection, and tailored electrics—delivering safe, reliable, and cost-effective transport in hostile environments.

This heavily modified U4023 was built for sole purpose of transporting people in an extreme offroad environment in Northern parts of Australia. Outfitted with ADR compliant seating, it is the ultimate off-road people transporter.

Upgraded U1700 built for frontline fire response. With a restored cab, Unidan bull bar and roof rack—both featuring integrated water sprayers—it delivers enhanced safety, rugged performance, and minimal downtime in demanding conditions.

Built for remote worksites and heavy-duty tasks, this U4023 packs a high-capacity tipper body, rear hydraulic winch, and GVM upgrade. Outfitted with Unidan gear, it’s a dependable solution designed for efficiency, durability, and all-terrain capability.

Not every truck needs to be built for a single purpose—that’s the philosophy behind the creation of this 6x6. Engineered with the versatility to handle both demanding tasks and recreational adventures, it strikes the ideal balance between work and play.
