Trains and emergency calls affected after major outage at Australia's largest telecoms company

This outage exposes critical vulnerabilities in Australia's telecommunications backbone—a foundational layer for military command-and-control, civilian emergency services, and economic function in a contested Indo-Pacific environment. A 12-hour failure affecting emergency calls, transport, and mobile networks demonstrates that peacetime soft-infrastructure weaknesses could catastrophically degrade Australian operational resilience during a crisis (kinetic scenario or large cyber attack), directly impairing Pillar 8 (Northern Arc / national continuity).
