Brisbane, Australia – 22 September 2026 – SUBCO today announced three new hypercables; APX North, APX East-2 and APX West, cementing demand for new subsea capacity to support AI-driven growth in the region.
APX North, a 9,500 km, 24 fibre pair system, will connect Sydney to Japan via Guam. This will be the first hypercable from Australia directly to the interconnection hub of Guam, and the first system to offer direct connectivity between Japan and Australia. Like SMAP, APX North will include switched branching units that allow selected fibre pairs to bypass landing in Guam and operate direct between Australia and Japan.
APX East-2 is a 10,000 km, 24 fibre pair hypercable connecting Guam to Los Angeles, designed to provide critical route diversity from the US to both Japan and Australia, via Guam.
“This segment is vital and will serve as the backbone for trans-Pacific traffic between Asia and the US, as well as providing diverse connectivity for Australia and Japan via APX North. We expect this system to be incredibly popular” said Founder & Co-CEO of SUBCO, Bevan Slattery.
APX West is a 4,600km, 24 fibre pair system connecting Perth to Singapore, with branches to Jakarta and Batam in Indonesia. The design of the system allows for additional resiliency and unprecedented flexibility through switching in and out of new regional interconnection hubs in Batam and Jakarta.
“Singapore and Indonesia remain critical to Asia's connectivity landscape, and their strategic importance will only grow as bandwidth demand accelerates, and new interconnection hubs are needed to deliver greater flexibility and route diversity. We are building as much of that as possible into our system design and making that available to our cornerstone customers through APX West,” said Slattery.
SUBCO is targeting completion of all three systems in 2029.
“I know it’s ambitious, but it’s achievable and it’s necessary. We are finalising the details of cable supply and vessels and expect to be Contract in Force on all three systems by early next year,” said Slattery.
“People have been slow to understand that AI factories are dead without massive subsea connectivity to carry tokens from factory to customers. Hundreds and hundreds of terabits per second. That’s why we are about to undertake the single largest subsea infrastructure build ever by a carrier in the Indo-Pacific. Not only is the build itself huge, but the timeframe is compressed with over 40,000km of cable to be installed in just over three years. Our team has signed up for the challenge, and will grow significantly as each system reaches CIF.”
SUBCO will be at Submarine Networks World in Singapore from 23-24th September 2026.
