Australia’s defence and aerospace manufacturing sector represents one of the most strategically important and technologically advanced industries in the nation. From naval shipbuilding to satellite technology, Australian manufacturers are playing an increasingly vital role in national security while driving innovation across multiple sectors.
A Sector of Strategic Importance
With the AUKUS partnership, growing regional security concerns, and a $270 billion decade-long investment plan, Australia’s defence manufacturing industry is experiencing unprecedented growth. This isn’t just about defence — it’s about building sovereign capability, creating high-skilled jobs, and developing technologies that benefit the broader economy.
The sector employs over 30,000 Australians directly, with many more in the supply chain. From engineers to precision machinists, these are high-paying, highly skilled positions that keep expertise onshore.
Naval Excellence: Austal and the Submarine Fleet
Austal in Henderson, Western Australia, stands as a global leader in high-performance aluminium vessels. The company has delivered patrol boats, frigates, and littoral combat ships to the Royal Australian Navy and the United States Navy alike. Their shipyard represents one of the largest defence manufacturing facilities in the Southern Hemisphere.
As Australia moves toward nuclear-powered submarines under AUKUS, the demand for precision manufacturing, advanced materials, and skilled labour will only intensify — creating opportunities across the entire supply chain.
Eyes in the Sky: Australian Aerospace Innovation
Australia’s aerospace sector is punching well above its weight. Gilmour Space Technologies on the Gold Coast is developing hybrid rockets to launch Australian satellites into orbit. Hypersonix Launch Systems is pioneering hypersonic scramjet technology that could revolutionise both space access and defence applications.
Meanwhile, Boeing Aerostructures Australia in Melbourne manufactures critical components for the 787 Dreamliner and military aircraft, demonstrating that Australian precision manufacturing can compete at the highest global standards.
Precision Defence Technology
Several Australian companies have developed world-leading defence technologies:
- CEA Technologies — Canberra-based developer of advanced phased array radar systems used by the Royal Australian Navy
- EOS Defence Systems — World leader in remote weapon stations and counter-drone technology
- NIOA — Australia’s largest privately-owned defence company, manufacturing ammunition and weapons systems
- Thales Australia — Manufacturer of Bushmaster protected vehicles that have protected Australian soldiers in conflict zones worldwide
The Supply Chain Opportunity
Defence manufacturing creates a ripple effect throughout the economy. Companies like Bisalloy Steels produce quenched and tempered steel plate for armoured vehicles. Quickstep manufactures advanced composite components for the F-35 Joint Strike Fighter program. Marand Precision Engineering builds complex assemblies for both aerospace and defence applications.
This supply chain diversification means smaller manufacturers can access defence contracts, building capability that translates to other high-value industries.
Why Australian Defence Manufacturing Matters
- Sovereign Capability — Reducing dependence on foreign suppliers for critical national security needs
- Technology Transfer — Defence innovation often leads to commercial applications in mining, medical, and telecommunications
- Skilled Workforce — Creates and retains engineering and manufacturing expertise in Australia
- Export Potential — Australian defence products are increasingly sought by allied nations
- Regional Security — Contributes to stability in the Indo-Pacific region
