Subco, a Privately Owned company headquartered in Australia, was founded in 2016 and operates with approximately 10 employees. The company specializes in data centre infrastructure, functioning as a provider of undersea network systems connecting Australia to the Middle East and beyond.
On October 7, SUBCO was evaluating two prospective additions to Australia’s subsea infrastructure capabilities: an uncrewed surface vessel for cable-route surveys and a dedicated cable-laying ship. Founder and co-CEO Bevan Slattery outlined these concepts at the AusNOG conference in Brisbane, noting the need to augment Australia's survey capabilities and establish its own vessel for laying and repairing submarine cables. This follows SUBCO's announcement on October 4 of three new subsea cable systems in the Indo-Pacific—APX North, APX East-2, and APX West—with a combined length of more than 40,000 km, which the company described as the largest subsea infrastructure build undertaken by a carrier in the region. Previously, on September 29, SUBCO detailed plans to build these three systems, spanning 24,000 kilometers across the Indo-Pacific by 2029, specifically to carry surging artificial intelligence (AI) data traffic. The company stated each of the three links would feature 24 fiber pairs connecting Australia, Japan, Guam, the United States, Singapore, and Indonesia, aiming to expand connectivity across the region to meet AI-driven demand for international bandwidth.
