Mega Datacentre Planned for Outer Melbourne: What Residents Need 2026

A mega datacentre planned for outer Melbourne is raising alarm among residents and environmentalists alike. Located in Plumpton, about 30km north-west of the Melbourne CBD, this proposed facility would be six times larger than the Chadstone shopping centre and consume more electricity than Victoria’s largest power station, Loy Yang A. As Australia’s datacentre boom accelerates, understanding the implications of this massive project is critical.

What Is a Mega Datacentre?

A mega datacentre is a large-scale facility designed to house thousands of servers, storage systems, and networking equipment. These centres power cloud computing, artificial intelligence, and streaming services. The Plumpton project, dubbed the Victorian AI Hub, could have a maximum capacity of 2.4 gigawatts (GW) — enough to power hundreds of thousands of homes.

Key Details of the Proposed Site

• Location: Plumpton, Victoria, near the Calder Freeway and Melbourne’s renewable energy hub
• Size: 350 hectares total; 140 hectares (40%) used for four datacentre buildings
• Comparison: Six times the footprint of Chadstone Shopping Centre
• Timeline: Construction not expected for at least two years, pending planning and environmental approvals

Environmental and Community Impact

The sheer scale of the mega datacentre has sparked community resentment even before construction begins. Residents received letters from developer Syncline Energy, but many learned of the project through social media, fueling distrust. Concerns include strain on local power grids, water usage, noise from backup generators, and visual impact on the rural landscape.

The AI Hub and Energy Consumption

The term AI hub reflects the datacentre’s intended role in powering artificial intelligence workloads. However, critics point out that the facility’s electricity consumption would exceed the output of Victoria’s largest coal-fired power station. A report by Data Centres Australia in April revealed 30 operational datacentres in Victoria, with 30 more in the pipeline — highlighting a nationwide trend.

Bullet List: Key Takeaways

• The mega datacentre in Plumpton is six times larger than Chadstone shopping centre
• It would consume more electricity than Victoria’s biggest power station
• Residents are concerned about environmental impact and lack of communication
• Construction is at least two years away, pending approvals
• Similar projects are surging across Australia, raising broader questions about sustainability
