About Us

Expertise. Experience. Reliability.

Since 1996, Impact Environmental Consultancy Pty Ltd has been the strategic partner of choice for councils right across Australia in managing their waste. We specialise in local government, bringing deep sector experience to better understand the challenges they face, the market they operate within, and strategic possibilities they can leverage to enhance business and environmental outcomes.

We’ve built a dedicated long-term team of consultants offering diverse experience across multiple areas. This enables us to tailor our services and advice to every council and client we work with, better capturing their local characteristics and strategic and project objectives. We embed our team deeply in each project, bringing a personal approach to problem solving that is highly valued by our many repeat clients.

While Impact has developed strong connections with private waste management companies through managing numerous local council waste service tenders, we have deliberately chosen to refrain from consulting on their behalf. This ensures we retain complete independence, providing our government clients with a high level of process security.

At Impact, we believe knowledge-sharing is vital to creating a better industry and outcomes for all. This is the impetus behind our industry-leading Coffs Waste Conference, uniting the sector each year to explore contemporary industry challenges and share cutting-edge innovation and expertise.

Thomas Freeman

Managing Director /Principal Consultant
B. Engineering (Environmental), M.A. (Education)

Thomas joined Impact in 2013 following a career in local government and became Managing Director in 2022. A true waste generalist, he has undertaken a wide variety of waste management consultancy projects, primarily in regional and rural Australia. His experience ranges from project-managing large NSW EPA grant projects to preparing options analysis for councils and going door-to-door for community engagement and consultation.

Thomas interacts with waste stakeholders at all levels, often acting as a fulcrum between the technical and regulatory environment set by the state, the boots-on-the-ground service delivery, and the wider community. He brings an environmental engineering approach to the provision of waste management services and draws upon his Master of Education to develop innovative training and education initiatives for the waste industry.
