Defence & Detention


Our capacity to meet stringent requirements around security, operational continuity and the need to work within complex and constrained environments has helped us maintain strong relationships with the defence, border protection and correctional sectors.

Working under a variety of contract types and delivery methods, we have partnered with various agencies to create training, civil, fire management, fuel infrastructure, accommodation, recreation, operational and logistic, health and welfare and detention facilities across a broad spectrum of locations and environments, including work on Manus Island, Papua New Guinea.

Decmil provides project and design teams experienced in delivering major defence and government projects under a variety of contract types and delivery methods including managing contractor, design and construct, head contracts and medium works contracts.

Our understanding of government processes allows us to foster partnerships to meet the exacting quality, safety, environmental, whole of life and security specifications demanded by defence and government bodies.

Our portfolio includes secure government and defence projects in Australia and offshore projects with complex logistic, cultural heritage and secure operational project management.

Our track record demonstrates our capability to manage the construction and commissioning of fully operational and secure facilities, optimising the design with innovative modular solutions, enabling faster construction and greater standardisation of core components.
