Sydney, Australia - 30 June 2026 - Vocus has announced plans to build Australia's first ducted long-haul fiber route between Sydney and Melbourne, launching a new digital infrastructure initiative designed to meet the rapidly growing connectivity demands of AI data centers, hyperscale cloud providers, and enterprise customers.
The project marks the first investment under the company's newly established Australian Digital Infrastructure Platform (ADIP) and will involve approximately AUD 500 million (~USD 330 million) in capital expenditure. Scheduled to enter service in 2029, the new route will be capable of supporting up to 6,912 fiber cores (3,456 fiber pairs), providing substantial headroom for future network expansion without requiring additional civil construction.
Unlike conventional long-haul fiber builds, the network will be constructed using a ducted architecture, allowing new fiber cables to be installed within underground conduits as capacity requirements increase. Vocus said the design improves resilience, accelerates future upgrades, and minimizes service disruption by eliminating the need for repeated excavation as demand grows.
The initiative is driven largely by the rapid expansion of AI infrastructure across Australia. Training and inference workloads are generating unprecedented volumes of east-west data traffic between hyperscale campuses, cloud regions, and interconnection hubs, increasing pressure on existing long-haul networks. Vocus said the new corridor is intended to provide the scalable backbone needed to support next-generation AI factories, cloud platforms, and high-capacity data centers.
Construction is expected to create more than 1,000 jobs, while the route will strengthen connectivity between Australia's two largest digital infrastructure markets. Sydney remains the country's primary cloud and network interconnection hub, while Melbourne continues to attract major hyperscale and enterprise data center investments, making the corridor one of Australia's busiest digital traffic routes.
The announcement follows several recent upgrades to Vocus' national backbone, including the completion of its Adelaide-Perth 2 (AP2) optical enhancement, which quadrupled transmission capacity across one of Australia's most critical long-haul corridors. Together with ADIP, these investments reflect the company's broader strategy of expanding national digital infrastructure ahead of expected AI-driven demand.
Industry analysts increasingly view fiber infrastructure as a critical enabler of AI data center growth. While computing capacity and power availability often receive the most attention, high-capacity terrestrial fiber is equally important for connecting geographically distributed AI campuses, synchronizing large datasets, and supporting low-latency cloud services. As GPU clusters scale into the hundreds of thousands of accelerators, backbone networks must also expand to accommodate significantly higher traffic volumes.
For Vocus, the Sydney-Melbourne project represents more than a telecommunications upgrade. It positions the company to support Australia's next generation of AI-ready digital infrastructure by delivering a scalable, resilient transport network capable of underpinning future hyperscale data center development. As AI investment accelerates across the country, long-haul fiber capacity is expected to become as strategically important as power, land, and cooling in enabling large-scale data center deployments.
