Australia is ramping up defenses for its critical subsea cables, which are essential for international data traffic. The government announced an A$18 million investment in the Cable Connectivity and Resilience Centre to protect these cables from threats including fishing boats, espionage, and natural disasters. Currently, 15 underwater cables carry 99% of Australia's international data. The Royal Australian Navy has identified these cables as both vital lifelines and significant vulnerabilities. Australia is collaborating with 16 other nations to establish the Guiding Principles for Underwater Infrastructure Defence Exchanges (GUIDE) to address the growing threats. The primary suspects for potential attacks are Russia and China, with recent incidents highlighting the cables' vulnerabilities. Defence Minister Richard Marles emphasized the need for a coordinated response to these threats, which have become unprecedented in scale and frequency.
