🔥 Trending Australian Federal Police Investigate 'Suspicious' Submarine Cable Fault

On Sunday, August 9th, 2026, two submarine communication cables off the coast of Western Australia experienced shunt faults within minutes of each other and in close proximity ³⁴. These cables are the Indigo West, which connects Australia to Singapore, and the Indigo Central, linking Perth to Sydney ⁵.

Details of the Incident

The faults occurred in the Submarine Cable Protection Zone off Perth, Australia ⁴. Subco, the owner of the cables, reported the faults, prompting its founder and CEO, Bevan Slattery, to send an "urgent message" to the Australian Federal Police (AFP) ³. The AFP is currently investigating the incident ³.

Suspicions and Concerns

The simultaneous and close-proximity nature of the faults has led to suspicions of deliberate activity. Naval experts have pointed to "suspicious activity by a nearby vessel" as a potential cause ⁵. This incident has raised concerns among defense experts about Australia's vulnerability to being cut off from global internet communication ⁶. Some experts suggest that the event highlights the country's high susceptibility to such disruptions ⁶.

While serious investigations are underway, there have also been satirical reports, such as one humorously suggesting a tiger shark named Trevor as a suspect ⁷. However, the primary focus remains on the official investigation into potential suspicious activity ³⁵.

Broader Context of Submarine Cable Vulnerabilities

Submarine communication cables are vital infrastructure for global internet and telecommunications ². While cable faults have decreased significantly over the decades due to improved burial techniques, with an average of 0.44 faults per 1,000 km per year after 1985, they are still a recurring issue, with more than 50 repairs needed annually worldwide ¹. The recent incident in Australia underscores the ongoing need for robust protection and monitoring of these critical underwater networks.
