SUBCO says SMAP hypercable construction is progressing with final splices planned and full service from May 2026.
Context
• Australian subsea cable developer SUBCO says the SMAP transcontinental hypercable project has achieved key construction milestones with final splices underway and an operational date set for May 2026. • The SMAP cable — designed to deliver 400 Tbps across Australia’s east-west route — highlights growing demand for high-capacity digital infrastructure, but observers note questions about cost, usage and broader competition remain. SUBCO, an Australian-owned undersea fibre network company, has confirmed major construction progress on the SMAP submarine hypercable, a transcontinental subsea system that seeks to connect Sydney, Melbourne, Adelaide and Perth with unprecedented bandwidth and resilience.

Analysis
In an update published in January 2026, SUBCO said the Perth–Adelaide–Melbourne section will reach its final splice this month, with services expected to be handed to customers in March 2026. The Melbourne–Sydney segment is scheduled to complete its final splice in March, and the full SMAP system is slated to be ready for service in May 2026. Once completed, the SMAP cable will deliver 16 fibre pairs and more than 400 Tb of capacity, representing the most significant transcontinental capacity upgrade in Australia in about twenty-five years. SUBCO founder Bevan Slattery said demand from hyperscalers, carriers and cloud providers has been strong, with most of the available fibre capacity already sold or reserved under contract. Work on landing stations has also been advancing. Cable landing station construction at Victoria’s Torquay has progressed following ceremonial completion of design and planning phases, and installation work at Adelaide’s landing station has begun, laying foundations for the systems that will interface between the undersea cable and terrestrial networks. SUBCO’s SMAP system has been under development since its first contract in force status in 2023 and was originally intended to launch in 2026. The cable was upgraded from twelve to sixteen fibre pairs to meet anticipated demand, boosting capacity by about 33 % over its original design.
