Prochem has been family-owned-and-operated in Mackay for over two decades by the Colvin family.

After managing Prochem Agencies Pty Ltd, John Colvin purchased shares in the company and within three years took full ownership. John has been involved in the resource sector for over 30 years working on the east and west coast, open cut and underground operations.

Following industry demand, we formed Prochem Haulage Pty Ltd to provide specialised transport & logistic haulage services within Central Queensland.

We are proud to be an Australian owned and operated business providing services for the resource, industrial and transport sectors.

As we have expanded our services over the years we have brought all facets of our business under the one umbrella – Prochem Group of Companies.

Today, we are proud to offer an extensive range of services including –

Truck Service Centre

Hydraulics Service Centre


Warehousing, Repackaging & Distribution

Infrastructure & Environmental Support

Engine Coolant Packages

Coolant Recycling Technology

Retail Outlet

Our team is made up of highly trained professionals, led by our Leadership Team, who utilise the latest industry technologies and techniques to ensure that all services are of the highest quality. Commitment to safety and sustainability is also at the forefront of all our operations, with a focus on providing environmentally friendly solutions wherever possible. Commitment to quality and customer satisfaction is reflected in every aspect of our operations.

Prochem’s General Manager is Ben Colvin, John and Selina’s eldest son. Ben is a qualified MEM Diesel Fitter, Heavy Vehicle Truck Mechanic and Auto Electrician.
