根据《2026年国家防务战略》（NDS），澳大利亚计划在未来四年增加140亿澳元的国防投资，未来十年增加530亿澳元。澳大利亚发布了《2026年国家防务战略》和《综合投资计划》（IIP），提出大幅增加国防开支，旨在提升军事能力、加强国家韧性并扩大国内防务工业基础。
澳大利亚国防部于4月16日宣布，政府已根据《2026年综合投资计划》承诺在未来10年内投入4250亿澳元（约合3050亿美元），用于澳大利亚国防军（ADF）的现代化建设。澳大利亚的首份NDS和IIP于2024年发布，旨在改善国防军的态势和能力，将军事力量与更广泛的国家资源和韧性相结合。2026年版的系列文件是在此框架基础上的进一步发展，并由进一步增加的国防开支提供支撑。
根据国防部的说法，澳大利亚将在未来四年的远期预算期内追加140亿澳元，并在未来十年内追加530亿澳元的国防资金。结合2024年NDS中的承诺，到2036年，总追加投资将达到1170亿澳元。因此，按照北约标准的计算方法，预计到2033年，国防开支占GDP的比例将上升至3%。
2026年国家防务战略（NDS）
《2026年国家防务战略》建立在2023年《国防战略审查》和2024年NDS的基础之上，其背景被国防部描述为“第二次世界大战以来最严峻的情况”。该战略强调了通过现代化建设应对日益复杂的地区安全挑战的紧迫性。
Under 2026 NDS, Australia plans defence investment worth an additional AUD14 billion over the next four years and AUD53 billion over the next decade. (Janes)
Australia has released its 2026 National Defence Strategy (NDS) and Integrated Investment Program (IIP), setting out a major uplift in defence spending aimed at enhancing military capability, strengthening national resilience, and expanding the domestic defence industrial base.
The Australian Department of Defence (DoD) announced on 16 April that the government has committed AUD425 billion (USD305 billion) under the 2026 IIP over the next 10 years to modernise the Australian Defence Force (ADF).
Australia's inaugural NDS and IIP were launched in 2024 to improve ADF posture and capabilities, integrating military power with broader national resources and resilience. The 2026 iterations of the documents build on this framework and are underpinned by a further increase in defence spending.
According to the DoD, Australia will invest an additional AUD14 billion over the next four years and AUD53 billion over the next decade in defence funding. Combined with commitments made under the 2024 NDS, this brings total additional investment to AUD30 billion over the four-year forward estimate period and AUD117 billion through to 2036.
As a result, defence spending as a proportion of GDP is projected to rise to 3% by 2033, calculated using NATO-style accounting methods, the DoD said.
2026 NDS
The 2026 NDS builds on the 2023 Defence Strategic Review and the 2024 NDS and is framed around what the DoD describes as the “most challenging circumstances since the Second World War”.
