A national advisory built on deep experience and critical infrastructure insight....

Devbase brings together more than 1,000 years of combined leadership and specialist experience across Australia’s energy sector. Our advisors have supported Australian asset owners, working across some of the most regulated, capital-intensive, and operationally critical infrastructure energy portfolios in the nation.

Collectively, our people have supported organisations operating more than 430,000 kilometres of gas and electricity networks, and production assets capable of over 1 billion gigajoules of energy each year — a scale that reflects the trust placed in us by businesses whose decisions influence system reliability, regulatory compliance, and public confidence.

Our team of advisors and specialist practitioners combine strategic insight with hands-on delivery experience. We understand the forces shaping today’s energy & resource infrastructure businesses — policy reform, regulatory cycles, shifting economics, evolving community expectations, and large-scale energy business transformation.

We specialise in solving the challenges that arise at the interfaces: between social licence and development, between development and execution, and between execution and operations. These are the transition points where risk concentrates and performance is determined.

Our proven Develop – Execute – Verify – Baseline (DEVB) model gives assurance to client leaders across these interfaces, exposing risk and allowing our team to integrate with your business to strengthen organisational capability, governance, role clarity, and embed fit-for-purpose processes and systems.

Underpinned by accurate data and disciplined analysis, we help leaders make value-based, safety-aware, and risk-informed decisions.

Devbase exists to support infrastructure-intensive organisations to perform through complexity, change, and scale , turning risk into progress and enabling sustainable results across Australia’s most critical energy and infrastructure businesses.
