The market is entering a period of rapid expansion with $26 billion in forecasted investment through 2030. This capital influx will drive a 129% increase in data centre capacity, growing from 1,350 MW in 2024 to 3,100 MW by the end of the decade.

The Bosun cable establishes Darwin as a critical digital gateway, linking Australia to Singapore and Christmas Island while bypassing politically sensitive South China Sea routes. By integrating with the Honomoana system, it creates a secure, high-capacity link between the United States and Asia via Australian domestic networks.

Strategic landing stations are being developed in Darwin, Melbourne, and the Sunshine Coast through partnerships with Vocus, SUBCO, and NEXTDC. These hubs are essential to supporting the projected 3,100 MW of national capacity required by 2030.
