Defence Expenditure
Key Capabilities
Advanced air combat and support fleet with F-35A, E-7 Wedgetail, P-8A, tankers, and long-range air mobility.
Modern navy centered on Hobart-class air warfare destroyers, frigates, amphibious lift, submarines, and future AUKUS undersea capability.
Improving air and missile defence through Aegis, integrated air defence modernization, and long-range strike programs, but limited national missile defence depth.
Professional land force optimized for regional operations, amphibious support, special operations, and growing long-range fires.
Strong Five Eyes intelligence integration, JORN over-the-horizon radar, cyber cooperation, maritime surveillance, and airborne early warning.
Strategic geography, northern Australia access, sustainment nodes, and U.S. rotational presence create major operational access value.
Growing naval, munitions, autonomous systems, and AUKUS-linked industrial capacity, though dependent on allied supply chains for high-end systems.
Among the most interoperable non-NATO partners through Five Eyes, ANZUS, combined exercises, common equipment, and operational history with NATO/U.S.-led coalitions.
