The Illawarra and Shoalhaven regions have a long and proud history of delivering innovative technology, advanced manufacturing, and critical services to the Australian Defence Force (ADF) and global defence industries. Today, this region is home to a highly skilled workforce, leading-edge research at the University of Wollongong, and world-class manufacturing and engineering capabilities that continue to support sovereign defence projects.

Illawarra’s steel manufacturing legacy remains a cornerstone of national defence capability. Port Kembla has long been a hub for specialty steels, including rated ballistic plates and aircraft-grade materials, supporting key defence assets such as Collins-class submarines, Adelaide-class frigates, and Hobart-class Air Warfare Destroyers. From the invention and production of the Owen submachine gun in the 1940s to modern advancements in high-performance steel, the region has played a vital role in Australia’s defence innovation.

Today, across the Illawarra and Shoalhaven, local businesses and industry leaders continue to drive defence capability through engineering excellence, maintenance and sustainment services, supply chain solutions, joint development initiatives, and cutting-edge research. The region’s commitment to defence resilience and innovation ensures it remains a strategic partner in strengthening Australia’s sovereign capability.
