As Defence accelerates digital transformation, digital infrastructure has become as critical to mission success as airfields, ports, and even roads. The challenge is no longer simply building facilities to store and process information. It is creating resilient, sovereign infrastructure that can operate securely and reliably amid growing strategic, environmental, and operational pressures.
The 2026 National Defence Strategy underscores the importance of this capability. Australia faces its most complex strategic environment since the Second World War, with greater emphasis on self-reliance, a resilient, sovereign industrial base, and an integrated force capable of operating in contested environments. Robust and protected ICT infrastructure is fundamental to these objectives. Without it, decision advantage, operational continuity, and the ability to generate effects across all domains are at risk.
Sovereignty must be the foundation. Defence cannot rely on offshore expertise or fragmented support models when national security and operational continuity are at stake. Sovereign capability extends beyond hosting data in Australia. It requires local engineering expertise, accredited operating practices, self-performance capability, and skilled teams to maintain critical systems and respond rapidly to incidents. In a contested environment, trusted local capability is a strategic advantage.
This aligns with the Defence Digital Strategy and Roadmap 2025, which prioritises a secure, integrated, and scalable digital environment to support Defence operations in the digital age. Data centres, ICT nodes, and modular facilities form a critical part of that digital backbone and must be designed, built, operated, and sustained to minimise dependence on external supply chains.
Resilience is equally important. Defence infrastructure must continue operating during disruptions to power, water, and communications while protecting sensitive systems from electromagnetic interference. The Square Kilometre Array Observatory (SKAO) in Western Australia demonstrates Australia's sovereign digital infrastructure capability.
Ventia, one of Australia and New Zealand’s largest essential services providers, delivered the Central Processing Facility and 19 Remote Processing Facilities, integrating specialised power, fibre, processing, and RFI-shielded systems across the telescope array. The project showcases sovereign expertise in delivering resilient, mission-critical infrastructure with direct relevance to Defence requirements.
Physical protection is also essential. Facilities handling Defence information must meet the requirements of the Protective Security Policy Framework and be certified for the appropriate physical security zones. Combined with effective electromagnetic shielding, these measures create infrastructure that is both digitally hardened and physically resilient, supporting force integration, decision advantage, and sustained operations.
Workforce capability remains a challenge, particularly in regional and remote areas. Continued investment in local talent pipelines, standardised operating procedures, and scalable service models is critical to strengthening sovereign skills and ensuring consistent performance across Defence's infrastructure estate.
EMF/RFI-shielded edge computing, modular ICT facilities, and containerised solutions offer practical pathways for rapidly deploying capability into remote and austere locations while maintaining common standards. Australia's successful delivery of complex infrastructure projects such as SKAO demonstrates that the expertise and capacity to deliver these solutions already exist domestically.
Digital infrastructure is no longer a passive asset. It is a strategic enabler of national security and Defence capability. By embedding sovereign expertise, incorporating advanced EMF and RFI shielding, designing facilities to meet stringent security requirements, and investing in workforce development, Australia can build a secure, adaptable, and resilient digital infrastructure ecosystem.
Resilient and protected ICT infrastructure is not optional. It is a core requirement for achieving the objectives of the 2026 National Defence Strategy and the Defence Digital Strategy, ensuring Defence is prepared for an increasingly contested and uncertain future.
