Construction is underway on GreenSquareDC’s flagship SYD1 hyperscale campus in Greater Western Sydney, as Australia’s data centre sector responds to rising demand for sovereign, AI-ready compute capacity.
GreenSquareDC has begun construction of a 100MW-plus hyperscale data centre campus in Greater Western Sydney, marking a significant step in the expansion of onshore digital infrastructure to support cloud, AI and government workloads.
The SYD1 campus, located in Greater Western Sydney, is being developed to deliver scalable compute capacity for hyperscale cloud providers, enterprise customers and public sector organisations. Facility operations are scheduled to commence in the third quarter of 2026.
According to the company, the project is designed to support high-density and AI-enabled workloads while prioritising energy and water efficiency. GreenSquareDC highlighted that the Australian Government’s National AI Plan highlights the importance of sovereign digital and compute infrastructure in capturing the economic and productivity benefits of AI.
“Our SYD1 project reflects the evolving role of digital infrastructure as an enabler of innovation and productivity,” said GreenSquareDC CEO Charles Penny. “The ability to house high-performance computing onshore within well-connected digital ecosystems is fundamental to Australia’s competitiveness in cloud and AI.”
Local impact
The construction programme is also expected to have a significant local economic impact, according to the company. GreenSquareDC said the development will generate hundreds of skilled jobs across engineering, construction, project delivery and specialist trades, with additional long-term roles created once the campus becomes operational. The company believes the project will further strengthen Greater Western Sydney’s position as a hub for critical digital infrastructure supporting national cloud and AI services.
SYD1 has already cleared several key development milestones. GreenSquareDC has secured Stage 1 Development Application approval, enabling delivery of an initial 15MW of capacity, which is targeted for completion in Q3 2026. The company has also appointed construction firm Erilyan as general contractor for the first phase, citing its experience delivering hyperscale and liquid-cooled data centre facilities.
In parallel, GreenSquareDC has obtained a Complying Development Certificate for demolition and enabling works, allowing full site activation to proceed. Together, these approvals position the project to scale toward its planned capacity of more than 100MW, with the company previously indicating a total campus potential of up to 110MW.
The Sydney development is backed by up to AUD 1.2 billion in investment from private markets firm Partners Group, providing the financial underpinning for GreenSquareDC’s ambitions to become a significant domestic player in Australia’s rapidly growing data centre market.
SYD1 also complements the company’s earlier acquisition of the former IBM and Kyndryl data centre facility at 3 Brookhollow Avenue in Norwest Business Park. That site provides approximately 20MW of existing capacity, with expansion potential to as much as 96MW, giving GreenSquareDC an immediate operational footprint alongside its greenfield developments.
Beyond Sydney, the company has secured land options in Melbourne and Perth as part of a national expansion strategy. GreenSquareDC said its facilities are being designed to support high-density computing while aligning with its “Five Pillars to Sustainability” framework, which emphasises operational efficiency, environmental stewardship and long-term economic value.
