From humble beginnings
Collier & Miller was founded in 1946 by Bill Collier and his wife Ruth, after Bill returned home from serving in the RAAF during WWII.
Starting out of a tin shed in Griffith, Bill began with welding, machining repairs, and building practical equipment for local farmers—grain silos, stock crates, and trailers. Long hours, hands-on work, and a focus on doing things properly quickly earned the business a strong reputation in the region.
In 1957, Ron Miller joined the business as a partner. While new to engineering, he shared the same work ethic, values, and a history of RAAF service. From that point on, Collier & Miller began to take shape as the business it is today.
Growing with the Region
As the region expanded with the development of the Coleambally Irrigation Area, so did Collier & Miller.
In 1962, the business moved to its current site on Jondaryan Avenue. Manufacturing grew to include harvesting equipment, landforming scrapers, and irrigation tools, while the addition of hydraulics, fasteners, and paint laid the foundation for today’s retail division.
The values established during these early years—hard work, respect for customers, and teamwork—remain at the core of the business today.
Expansion & Innovation
In the 1980s, Ron Miller’s son Peter Miller joined the business and went on to become General Manager in 1987.
Under his leadership, Collier & Miller expanded significantly— with Peter leading growth in the retail division, investing in new facilities, and developing the engineering workshop into a large-scale operation. This included the construction of a 6,000m² workshop and major upgrades in equipment and capability.
In 2008, the third generation, Chris Miller, joined the business and became General Manager in 2014. Since then, the engineering workshop has expanded to more than 14,600m², with continued investment in technology, machinery, and capability.
The business has also broadened its machinery range, entered the cotton industry, and expanded into new geographic markets.
Collier & Miller today
Today, Collier & Miller employs over 160 people across a 20,000m² site in Griffith.
Still family-owned and led by Chris Miller, the business remains grounded in the same values it was built on—quality, practical solutions, and dependable service.
Those values show up in long-standing customer relationships, a highly experienced team, and a business that continues to evolve while staying true to where it started.
