Engineering1
Metal trade industries1
Oil refining12
Petrochemicals1
Food processing1

While these sectors have historically been significant, the manufacturing landscape in Sydney has undergone substantial changes. Many industries have relocated from the inner city to outer suburban areas, and the sector as a whole has faced challenges such as factory closures, international competition, and a shift toward service-related activities. In response to these pressures, newer manufacturing efforts in the region have increasingly focused on innovation and niche capabilities, including the production of medical, biomedical, pharmaceutical, and surgical products, as well as aerospace components, architectural aluminum, and computing equipment.12
