Transforming Challenges Into Sustainable Solutions

Founded in Adelaide, Trilogy Consulting is a rapidly growing multidisciplinary consultancy integrating environmental, geotechnical and drone-based expertise to deliver better outcomes across complex and disturbed sites.

Our Story

Built to Do Things Differently

Trilogy was founded on a simple observation: environmental, geotechnical and drone survey work are routinely handled by separate firms — creating gaps, rework loops and unnecessary cost.

By combining these disciplines under one team, we give clients a single point of accountability, faster decision making, and outcomes that are better because the disciplines talk to each other from day one.

Since founding in 2024, we have grown to a multidisciplinary team of 12+ highly qualified and experienced staff while leading remediation strategy across some of South Australia's most complex brownfield redevelopments.

The Numbers

What We've Delivered

Over 17,000 tonnes of soil diverted from landfill on a single project — eliminating 1,700 truck movements and 136,000km of transport.

Approximately $10 million saved for a client by identifying and managing an unforeseen site condition before it became a cost blowout.

12+ staff across Environmental, Geotechnical, Drone Surveys and 3D Modelling — all under one roof, one contract.

Our Values

How We Work
