Experience Audio with a difference

The Combat Wombat Term used to describe infantry soldiers away from home location as he "eats, roots, shoots, and leaves". Also a common name for a digger who is rather short and chubby (resembles the shape and size of a wombat). And for this purpose a portable sound system!  

With over 500 units sold in the past eight years, these handcrafted audio systems have earned a loyal following that includes veterans, celebrities, RSL branches, and even the Australian Army—who have gifted them to officers. Built for versatility and durability, they’re perfectly suited for use at home, in the shed, the caravan, or out at the campsite. 

Powered by a 12-volt system, these units offer versatile charging options without compromising on sound quality, thanks to the premium Yamaha amplifier board at their core. Each system comes equipped with a 12V / 2.3Ah sealed lead-acid (SLA) battery, known for its reliability and safety. When properly maintained, this type of battery can deliver up to six years of dependable performance. It’s easily rechargeable via your car or 240 volts at home, safe to use, simple—and affordable—to replace when the time comes. 

Each unit features an authentic .50 Caliber ammunition box, sourced from military surplus originating from Australia, New Zealand, the United States, or NATO forces. These rugged steel boxes are carefully restored and resealed to ensure durability and longevity, while still preserving the unique character, wear marks, and history earned through their original military service. No two are exactly alike—each bears the subtle scars and patina that tell a story, making every unit not just an audio system, but a piece of military heritage repurposed for modern use.
