Who is
Simpson Earth?

Simpson Earth is owned and operated by Mark Simpson.

Mark grew up in the Illawarra, becoming involved in the earthmoving and heavy haulage business by working with his father at the early age of 15 years old.

Simpson Earth has been operating for over three generations with Mark’s son, heavily involved in the operations of the business.
There is little the Simpson’s don’t know about the industry.
Their comprehensive skills, knowledge and passion for earthmoving stem from a lifetime of hands-on experience.

We pride ourselves on employing staff that share our enthusiasm for the industry. Our business is built on safety and delivering the highest standard of work for our clients. Our team executes projects that they are justly proud of, and as a result, our list of clients and projects continues to grow.

Our community involvement

As a proud local business, we value giving back to the Illawarra community. Our team has participated in the Illawarra Convoy from day one. The Illawarra Community Foundation helps children suffering from cancer and is ranked as Australia’s most trusted children’s charity. We continue to be involved year after year, contributing to the welfare and support of child cancer victims and their families.
