Subco is a Privately Owned company headquartered in Australia. Founded in 2016, with approximately 10 employees, the company reported $1.3M in revenue as of 2023. The company specializes in data centre infrastructure, functioning as a provider of undersea network systems that connect Australia to the Middle East and other regions.
Subco expanded its Australian footprint on March 19, 2026, introducing geographically diverse inter-capital connectivity and new data center access points, which strengthened resilience across the country’s telecom infrastructure. The company stated its Sydney-Melbourne route now operates across two geographically independent paths, delivering diversity along Australia’s busiest corridor. Previously, on March 18, Subco announced it expanded its Australian network with additional route diversity between Sydney and Melbourne, alongside new data center access points across major cities, specifying the Sydney-Melbourne connection operates across two geographically independent paths combining subsea and terrestrial infrastructure for improved resilience. This followed its March 17 revelation that it would harden the resilience of the busy Sydney-Melbourne stretch of its east-west transcontinental Australian cable system (SMAP), by splitting the segment between east coast capitals to run across independent subsea and terrestrial paths. Subco had also detailed on March 17 an expansion of its Australian network footprint with additional route diversity and new data center access points, confirming the Sydney-Melbourne route's two independent subsea and terrestrial paths.
