AirTrunk MEL3 Melbourne Data Center: Hyperscale AI Infrastructure Hub
Status: Planning / Land Acquisition & Pre-Development | Location: Northwest Melbourne Metropolitan Corridor, Victoria, Australia
Project Overview
The AirTrunk MEL3 Data Center Campus represents a major long-term hyperscale expansion of AirTrunk’s digital infrastructure platform in Melbourne, Victoria, reinforcing the city’s position as one of Australia’s leading cloud and AI infrastructure hubs. Strategically developed to meet the accelerating demand for artificial intelligence (AI), hyperscale cloud computing, high-performance computing (HPC), and enterprise digital transformation, the campus is designed to provide scalable, high-density capacity beyond central Melbourne while complementing AirTrunk’s existing MEL1 and MEL2 facilities. Engineered around AirTrunk’s industry-leading ultra-efficient, low-PUE design philosophy, MEL3 incorporates advanced energy-efficient infrastructure, intelligent building management systems, and next-generation cooling technologies to maximize operational performance while minimizing environmental impact. The campus is equipped with dedicated high-voltage substation integration to deliver resilient, large-scale power capacity capable of supporting demanding GPU clusters and AI model training environments. It is also designed with advanced liquid-to-chip cooling compatibility, enabling efficient thermal management for high-density compute deployments and future generations of AI hardware. Sustainability forms a central component of the development, with operations supported by 100% renewable energy matching and infrastructure designed to reduce carbon emissions while maintaining industry-leading efficiency. As a carrier-neutral facility, MEL3 will provide diverse fibre connectivity, seamless access to major cloud platforms, and low-latency interconnection with national and international networks, supporting hybrid and multi-cloud architectures. Backed by resilient power systems, comprehensive physical security, and future expansion capability, the AirTrunk MEL3 Data Center Campus delivers a secure, scalable, and future-ready digital infrastructure platform that strengthens Australia's capacity to support AI innovation, cloud growth, and long-term enterprise digital transformation.
