Works Underway On Vital Defence Precinct Upgrades

Dept of Infrastructure, Transport, Regional Development and Communications

Vital transport infrastructure upgrades to accommodate the increased activity being driven by South Australia’s burgeoning defence industry have now commenced.

With Osborne gearing up to become the home of Australia’s nuclear-powered submarine program, the Albanese and Malinauskas Labor Governments are delivering $100 million package of upgrades to ready the Lefevre Peninsula’s road network.

Transport, utility and social infrastructure upgrades are needed to accommodate the expanding workforce and enable successful delivery of the AUKUS program.

The Lefevre Peninsula upgrades include:

  • realignment and upgrade of the Victoria Road and Pelican Point Road junction
  • upgrades to the Victoria Road and Veitch Road junction
  • improved bike access, footpaths and new landscaping adjacent to the upgrades
  • new LED road lighting, line marking and drainage.

Early works, which include establishing a site, levelling the ground and clearing vegetation, are now underway at the corner of Victoria and Pelican Point roads.

Soil preloading earthworks are also underway and will prepare the soft soil for major construction by compressing the ground layers until they become firm enough to hold the approach roads.

These works are being done in close coordination with SA Water’s works in the area.

Equally funded by the Australian and South Australian governments, the $100 million project will support future growth of passenger, freight and defence industry traffic. This will ensure the road network continues to operate safely and efficiently.

Major construction on the Lefevre Peninsula upgrades is expected to commence in early 2027. The project will support the creation of 200 jobs per year for the life of the project.

To accommodate future growth, the Australian and South Australian governments have also committed $7.5 million each over two years in their 2026-27 Budgets to complete a planning study and business case to identify further transport infrastructure upgrades required to support increased demand.

The South Australian Government also recently announced a proposal to establish its first dedicated State Development Area (SDA) at Osborne.

The SDA would establish a central point for the coordination, planning and facilitation of economic and infrastructure development within this important industrial precinct.
