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 August 21, 2026, Subco, a private submarine cable operator, urged the Australian Federal Police (AFP) to investigate damage to two of its submarine cables, raising questions about "Safety Zones" in the wake of similar incidents in the Baltic Sea. This development followed the AFP's assessment of a crime report on August 14, 2026, concerning two Subco-owned subsea communication cables—Indigo-West and Indigo-Central—that developed "shunt faults" close to each other off Perth. Subco's founder and chief executive, Bevan Slattery, stated the faults occurred inside Australia’s federally declared Submarine Cable Protection Zone off Perth. Earlier, on August 13, 2026, the AFP was asked to investigate how these two subsea fiber-optic cables, which carry Australia’s internet traffic, were damaged off the Western Australian coast in early August. The INDIGO West and INDIGO Central cable systems, associated with Subco, first suffered these shunt faults in close succession over the weekend of August 8–9, 2026.
