Northern Australia has become Australia's principal strategic operating base. As the nation's forward line of deterrence and power projection, its ability to support sustained military operations will be critical in any future crisis or conflict. If deterrence fails, Australia's capacity to generate, sustain and recover combat power will depend not simply on individual bases or capabilities, but on the resilience of the interconnected systems that underpin northern defence.
Over the past decade, Australia has made significant investments in northern defence infrastructure, force posture and alliance integration. However, existing assessment approaches largely measure projects delivered, funding allocated and capability acquired. They provide limited insight into whether the broader defence ecosystem can continue operating under sustained disruption, adapt to changing conditions or recover from attack.
This report introduces the Preparedness, Resilience and Redundancy (PRR) Scorecard – a practical framework for assessing northern defence as an integrated operational ecosystem rather than a collection of stand-alone projects or capabilities.
The PRR Scorecard evaluates three complementary dimensions of operational readiness:
- Preparedness – the extent to which systems are planned, resourced and ready before disruption occurs.
- Resilience – the capacity of systems to absorb shocks, adapt under stress and continue supporting operations.
- Redundancy – the availability of alternative pathways, backup capacity and surge mechanisms that prevent local disruption from cascading into operational failure.
Applying the framework across nine critical domains, the report demonstrates how vulnerabilities in one system can rapidly affect others, reducing operational endurance and increasing strategic risk. It argues that strengthening Australia's northern defence posture requires a shift from assessing individual capabilities to understanding how the defence ecosystem performs as a whole.
At a time of growing strategic uncertainty and increasing pressure on defence budgets, workforce and industrial capacity, improving operational effect is no longer simply a matter of investing more. It requires making better decisions about where limited resources will have the greatest impact on preparedness, resilience and deterrence.
The PRR Scorecard provides policymakers, Defence planners and industry with a practical decision-support framework to identify systemic vulnerabilities, prioritise investment and strengthen Australia's ability to sustain military operations under pressure. By shifting the focus from measuring what has been built to assessing what the system can actually deliver in crisis, it offers a new approach to strengthening Australia's preparedness, resilience and deterrence.
