The ANAO could assess the Department of Defence’s development and delivery of selected autonomous maritime capabilities (uncrewed). The 2024 National Defence Strategy (NDS) identified the investment in uncrewed and autonomous systems as one of the government’s key priorities. The 2026 NDS emphasised government’s continued investment in the development of autonomous underwater and surface vessels and the role of the autonomous capabilities such as Ghost Shark, Bluebottle and Speartooth in providing ‘opportunities to strengthen the long-term commercial viability of Australian production lines’ as well as the potential for ‘significant export opportunities.’ The 2026 Integrated Investment Program (IIP) documents a planned investment of between $4.8 to $5.8 billion over the decade in the development of autonomous and uncrewed undersea warfare capabilities. An audit could provide independent assurance to the Parliament on Defence’s acquisition processes for these uncrewed maritime capabilities to determine if the desired effect is being delivered.
