Critical submarine cables: a deep dive into undersea infrastructure

In this episode of the National Security Podcast, Samuel Bashfield and Anthony Bergin join William Stoltz to discuss the importance and vulnerabilities of submarine cables.

In the Indo-Pacific, submarine cables carry over 95 per cent of international data traffic, including telephone and data communications. But they are vulnerable to a variety of environmental, accidental and malicious threats.

Samuel Bashfield and Dr Anthony Bergin, join Dr William Stoltz, to analyse the current challenges facing undersea cable infrastructure in the Indo-Pacific, and policy recommendations that could increase their resilience.
