Frequently Asked Questions

The Tasman Ring project establishes a 6,000 km subsea network providing 540Tbps of capacity. This infrastructure is designed to integrate the two markets, supporting the 99% of transoceanic traffic that relies on subsea cables for regional digital resilience.

Deployable capacity in Australia is forecast to more than double, rising from 1,350 MW in 2024 to 3,100 MW by 2030. This growth is underpinned by a projected $26 billion in capital investment into the data economy.

The high-capacity link allows for load shifting to New Zealand, where hydroelectric resources offer a sustainable energy solution for AI processing. This integration is critical as Australia scales toward 3,100 MW of capacity by the end of the decade.

The industry faces a severe talent deficit, with a requirement for 8,300 additional technical roles by 2030. This workforce shortage poses a direct threat to the execution of the $26 billion investment pipeline currently driving the sector.
