FROM HUMBLE BEGINNINGS, GREAT THINGS EVOLVE

Our Heritage

The Holmwood story began in 1950–51 with the formation of AMA (Adams, Mellish & Anderson) on the outskirts of Brisbane. Early on, AMA secured a contract to refurbish an ex-war aluminium tanker — at a time when aluminium welding technology was virtually unknown in Australia. This led to the importation of the country’s first aluminium welding equipment and expertise, setting the foundation for industry innovation.

By 1956, AMA was manufacturing its own aluminium tankers, including some of the largest petrol tankers seen in Australia at the time.

In 1963, Sid Mellish and Eddie Gumbelis established Holmwood Enterprises, named after a park in England. The business grew steadily, with Colin Mellish continuing the family legacy in Queensland. In 1985, a partnership with Alex Stables expanded operations into Victoria, strengthening the Holmwood brand nationally.

An Industry Leader

During the 1980s, Holmwood acquired Highgate Engineers (formerly part of Comalco via Industrial Engineering), a recognised leader in aluminium tankers and tippers. Today, Highgate Engineers specialises in the manufacture of fuel, water, and hydraulic tanks, along with associated accessories, supplying OEM solutions both locally and internationally.

The group continued to grow with the 1999 acquisition of Narwhal Fluid Quip, a leading manufacturer of fuel and lubrication service vehicles for mining, oil, contracting, and government sectors, with payload capacities exceeding 85 tonnes.

In 2000, Holmwood acquired Hockney Alcan, a well-established name in aluminium tankers and tray bodies. Hockney’s innovations — including the original one-tonne aluminium tray — remain influential today, with designs now integrated into the broader Holmwood Highgate offering.

Today, the Holmwood Group remains 100% Australian-owned and family-operated by the Mellish (QLD) and Stables (VIC) families. Our focus is simple: long-term customer relationships, dependable products, and solutions built to last.
