Under the Stage 3a upgrade, modernised infrastructure and services will be delivered to the Royal Australian Navy (RAN) to support its operations in the Indian Ocean. The current investment is expected to help upgrade essential infrastructure such as the wharves, power, water and security systems.
Many of Australia's future warships, including the Future Frigates and Future Submarines, will call HMAS Stirling home.
The first three contracts for the upgrade have already been awarded to local companies for the development of the causeway armour, concrete remediation and fender steelwork trade packages.
The Department of Defence has engaged Doric as managing contractor to plan and design the multimillion-dollar redevelopment, and Duratech and WA Limestone have been subcontracted for other parts of the project.
The three contracts have a combined value of $37 million and the remaining 19 trade packages are expected to be awarded over the coming months.
Work on the project is expected to be completed in early 2020, with the upgrades to meet requirements until at least 2030.
The upgrades are part of the federal government’s $200 billion investment in defence capability over the next decade.
