Responding to surging AI infrastructure demand, Vocus is committing A$500 million to build a new ducted fibre network between Sydney and Melbourne. This project targets the increasing data traffic in Australia's key digital corridor and aims to future-proof the country’s capacity for AI workloads.
- A$500 million investment for new fibre network by 2029
- First ducted long-haul route in Australia to enhance cable protection
- Over 1,000 jobs expected from the infrastructure rollout
What happened
Vocus, supported by Macquarie and pension fund Aware Super, announced plans to invest approximately A$500 million (around $343.5 million) to build a new fibre optic network connecting Sydney and Melbourne. This new route will be the first ducted long-haul network in Australia, designed to protect the delicate underground cables with specialized conduits. The project is slated for completion by 2029 and is set to create more than 1,000 jobs during the development phase.
The Sydney-Melbourne corridor currently accounts for roughly 40% of Australia's long-haul data traffic. Vocus highlighted a looming undersupply of network capacity that risks hampering data centre growth unless new infrastructure is deployed soon. This network expansion aligns with Vocus’s Australian Digital Infrastructure Platform initiative and follows its acquisition of TPG Telecom’s fibre assets in 2025.
Why it matters
The rapid surge in AI-driven data centre demand worldwide is pushing network infrastructure to its limits. Global spending on AI infrastructure is projected to reach $700 billion in 2026, reflecting massive investment by major technology firms seeking to enhance their compute capabilities. Australia currently faces deficiencies in both terrestrial and subsea networks needed to support existing and future AI workloads effectively.
By investing in this ducted fibre network, Vocus aims to position Australia as a competitive digital infrastructure hub. The deployment of ducted technology, already common in North America and Europe for cloud and AI providers, will improve resilience and reliability for data transmission across one of Australia's busiest corridors, better accommodating the escalating volume of AI-generated data.
What to watch next
Key milestones to follow include the project's progress toward its 2029 completion target and the scale of job creation resulting from the infrastructure rollout. Monitoring how well the ducted fibre network meets the anticipated demand surge will also be critical to evaluate its impact on Australia’s data ecosystem.
Further developments may also arise from Vocus’s broader strategies under the Australian Digital Infrastructure Platform, including possible expansions or upgrades in response to evolving AI infrastructure needs. Additionally, how other regional players respond to this significant investment could influence competition and cooperation in Australia’s digital infrastructure landscape.
