Who we are

An consultancy
built for complexity.

Greville Consulting is an Australian project management and engineering consultancy operating across South Australia, Victoria, and Queensland.

With a growing team of close to 30 professionals, we are well positioned to support Australia’s next wave of infrastructure delivery. Our approach is grounded in quality, responsiveness, and a genuine commitment to both our clients and our people.

Our experience spans a broad range of sectors, including rail, utilities, tunnels, roads, and bridges. Whether embedded within project teams or supporting critical delivery phases, we bring a practical, solutions-focused approach to every engagement.

How we work

Flexible
by integration.

Greville is built for flexibility and we understand project needs evolve, often rapidly. Our consultants are trusted to step in wherever they're needed most, whether that's short-term support through a critical phase or sustained involvement across a project's full lifecycle.

Our ability to mobilise fast, integrate seamlessly into existing teams while contributing meaningfully is a defining strength of how we operate.

"We believe that the right people given the right environment and leadership deliver exceptional outcomes. That belief is at the core of everything Greville does."

Sami Varasteh — Managing Director, Greville Consulting
