Key takeaway
In this episode, Todd Crowley breaks down the most critical, unaddressed blind spot in Australian national security: the physical infrastructure of the internet.
He covers the strategic reality of what happens when the Pacific’s digital nervous system goes dark. Garden-hose-sized cables severed 3,500 meters deep. The dangerous myth of satellite redundancy. Why AUKUS interoperability collapses the moment the fiber optics are cut. And how China built a decoupled network expecting conflict, while the West built one assuming cooperation.
Australia is planning for a future with nuclear submarines and missiles. But the actual vulnerability is a garden hose lying on the ocean floor.
Picture a cable roughly the diameter of a garden hose lying on the ocean floor, 3,500 metres down. It carries 95% of international data traffic, including classified military communications, financial transactions, and the digital nervous system of the Second Island Chain. Now consider this: a recent CSIS report confirms that China has already demonstrated the capability to sever these cables at extreme depths silently and with plausible deniability.
In this episode of Intelligence Optimised, Todd Crowley cuts through the noise surrounding Indo-Pacific security to confront the single most critical infrastructure vulnerability facing Australia and its allies. While deep-sea infrastructure sits at the heart of allied interoperability and AUKUS integration, Australia currently lacks an operationally tested contingency plan for a realistic cable-cut scenario.
Using the real-world example of Taiwan’s Matsu Islands—where cables were severed 12 times in a single year—Todd maps out why our current reliance on satellite backups and commercial workarounds like Starlink will fail under pressure. Commercial and military networks share the same physical infrastructure, meaning a coordinated attack on regional connectivity strikes both targets at once.
This is not about speculative threat modelling; it is about infrastructure intelligence. If a Pacific contingency occurs, deep-sea sabotage will not just disrupt communications for an afternoon—it will freeze financial markets and blind command structures during the critical initial 72-hour window.
To lift regional resilience and protect Australian national interests, Todd outlines three practical steps for defence planners and critical industry executives:
1. Enact genuine geographic routing redundancy to eliminate single-point failures.
2. Preposition dedicated cable repair capacity within the Indo-Pacific to reduce multi-week repair timelines.
3. Build and rigorously test a degraded communications operating concept for ADF command and control.
