Who We Are

Started in 2009, THEM Earthmoving Pty Ltd has a long connection to Geraldton, the Mid-West and regional Western Australia. 

Started by Stephen and Katrina-Lee O'Brien, this family owned and operated business has three generations of the family working in the business, with a local face to ensure you get the highest quality of work possible. 

Both Stephen and Katrina-Lee are lifelong residents of the Mid-West, with their grandparents emigrating to the region in the 1950's, a region both families have not left since. 

THEM began from humble beginnings, with the purchase of their first machine 9 years ago; a loader. 

Over the past decade the business has grown substantially, with both a larger fleet of vehicles for hire and a core group of fully trained staff available for work right across regional Western Australia. 

The contracts THEM are now capable of fulfilling range from multi-million Government and Corporate contracts to small private works. 

THEM Earthmoving strives for a future that allows us to integrate newer technology and equipment with a high quality of customer satisfaction. Our goal is to be respected for the quality of work we perform. 

We are passionate about the future and the opportunities that come with it. We are always looking for new challenges, new opportunities and new adventures that can allow us to expand our services and grow our regional small business.
