His career spans government, client, delivery partner and contractor roles, providing him with a rare end-to-end perspective on major program development, integration and delivery.

At Arup, Giles Thomas will play a key role in supporting governments and clients to shape and deliver complex transport programs that unlock long-term economic, social and environmental value for cities and regions.

“High speed rail and major transport programs are fundamentally city-shaping investments,” said Michael McGowan, Arup’s APAC Transport Leader. “Giles brings deep global experience in integrating complex systems, aligning stakeholders and making best-for-program decisions at scale. His appointment significantly strengthens our ability to support clients as Australia progresses its high speed rail ambitions.”

During his career, Giles Thomas has led multidisciplinary teams of engineers, planners, architects and environmental specialists, and has been responsible for system-level integration, technical assurance, investment decision-making and performance improvement across major programs. He has also worked extensively within complex regulatory and governance environments, advising governments, regulators and senior decision-makers.

“Giles has consistently operated at the intersection of engineering excellence, commercial performance and public value,” McGowan said. “His leadership on globally significant projects will help our clients navigate complexity, manage risk and deliver infrastructure that genuinely reshapes cities and communities for the better.”

Commenting on his appointment, Giles Thomas said he was excited to join Arup at a pivotal moment for Australia’s transport future.
