This report examines the role of hyperscalers as drivers of the subcable market and the geostrategic context of subcable systems; it highlights the significance of these developments for Australia, exploring both the potential benefits and challenges.

Submarine cable networks are critical infrastructure; they carry nearly all public internet and private network data traffic, facilitating global economic and financial activity as well as government and military communications and operations.

The submarine cable landscape has entered a new era and is now shaped by the rising participation of hyperscalers—hyperscale cloud and content providers— as well as the strategic actions of major powers and minilateral groups. The report examines the significance of this for Australia and explores how Australia can capitalise on these evolving dynamics to solidify its position as a regional digital hub in the Indo-Pacific by improving regional subcable resilience and digital connectivity, including its own.

This report makes five key recommendations, including that the Australian Government supports and strengthens regional repair and maintenance capabilities, ensuring that the management and protection of cables remains best practice, while continuing to work with regional partners to shape the regulatory norms and standards of the region. Additionally, to manage risks to Australia’s data security and digital economy ambitions, this report recommends that the Australian Government engages more closely with industry, makes potential regulatory adjustments, and maintains strategic oversight and vigilance to digital supply-chain dependency risks and anticompetitive behaviour.

Not only will those measures build connectivity and resilience domestically and regionally, but they align with Australia’s foreign-policy, development, security and cyber objectives, and will also support Australia’s growth and attractiveness as a subcables hub.
