A Family Legacy

This family-run business is truly a multigenerational endeavor. With three generations actively involved, THEM Earthmoving embraces a close-knit family dynamic. From aunties and uncles to nieces and nephews, parents, and children, the family bond extends through every aspect of our operations.

Our Journey

Established in 2009, THEM Earthmoving Pty Ltd has deep roots in Geraldton, the Mid-West, and regional Western Australia. Both founders, Stephen and Katrina-Lee, are lifelong residents of the Mid-West, tracing their connection back to the 1950s when their grandparents first emigrated to the region—a place both families have called home ever since.

From Humble Beginnings to Current Success

Beginning with just a singular Samsung Loader, THEM Earthmoving has grown significantly over the last 15 years. Thanks to the hard work of dedicated employees and the determination of Stephen and Katrina-Lee, the company has achieved remarkable success. What started as a modest venture has transformed into a thriving enterprise, now operating from its newly constructed depot—an evolution from its humble backyard beginnings.

15 Years and Beyond

As we celebrate our 15-year milestone, we look back with gratitude for the journey that has brought us here. With a legacy built on hard work, dedication, and a commitment to excellence, THEM Earthmoving looks forward to continued growth and success in the years to come.

The biggest question over the last 15 years is "Why THEM?". THEM is more than just a word; it's an acronym representing our core services: TRANSPORT, HAULAGE, EARTHWORKS, and MECHANICAL. This not only encapsulates our business model but also provides a memorable representation of who we are and what we do.


Community Commitment

Deeply rooted in the local and remote communities we serve, THEM Earthmoving takes pride in giving back. Stephen and Katrina-Lee actively participate and sponsor various sports and local events, contributing to the vibrancy and well-being of the broader community.
