GreenSquare Data Centers

What GreenSquare Data Centers does

GreenSquare Data Centers (GreenSquareDC Pty Limited) is an Australian sovereign developer and operator of hyperscale, AI-ready data centre campuses headquartered in Sydney. The company builds and operates two flagship campuses: SYD1 in Norwest Business Park, Greater Western Sydney (up to 100MW+ of IT capacity, with Stage 1 delivering 15MW and Stage 2 adding 80MW endorsed by the NSW Investment Delivery Authority and on track for operations in Q3 2026), and MEL1 in Spotswood, Melbourne (up to 240MW expected live in 2027). Both campuses are engineered around a closed-loop hybrid cooling system that operates water-free for most of the year, target PUE of less than 1.23-1.24 and WUE as low as 0.1, and a 132kV or 220kV power infrastructure designed for AI GPU clusters. At SYD1, GreenSquare applies an adaptive reuse strategy that retains 92% of existing structural carbon, delivers 275% more IT capacity within the original building footprint, and preserves 5402 tCO2e of embodied emissions.

The company monetises this capacity through long-term take-or-pay colocation contracts with global hyperscale cloud providers and cloud operators, supplemented by enterprise and Australian federal and state government customers requiring sovereign onshore compute. GreenSquare goes to market through direct enterprise field sales, with the Spotswood community engagement, LinkedIn presence, owned website content, and industry memberships (Water Stewardship Asia Pacific, Green Building Council Australia, Data Centres Australia) supporting demand generation. Pricing is not publicly disclosed and is negotiated individually by capacity.

GreenSquare was founded in 2021 by property developer Walt Coulston and acquired by Swiss private markets firm Partners Group in March 2025, which committed up to AUD 1.2 billion to build the platform. Founder Walt Coulston remains as director, and the executive team is drawn from AirTrunk, AWS, CDC Data Centres, Vantage Data Centres, NEXTDC, Equinix, BGIS, and Uniti/Nextgen. Plans for a Perth campus were dropped in 2026, concentrating the platform footprint on New South Wales and Victoria.

Scale indicators6 records

Recent moves10 records

Expansion highlights6 records

Emerging players

• EdgeConneX: Hyperscale and edge data centre operator serving cloud providers and large enterprises. Comparable on the hyperscale anchor-tenant model but with a global, edge-influenced footprint rather than concentrated sovereign-Australia positioning.
• Yondr Group: Hyperscale data centre developer focused on >100MW campuses. Highly comparable in capacity tier and customer profile but operates predominantly in EMEA and the Americas with limited Australian presence, making it an emerging global hyperscale peer rather than a direct Australian competitor.
• Stack Infrastructure: Hyperscale-focused data centre developer serving the largest cloud and AI customers. Comparable on capacity scale (>100MW campuses) and customer base, though primarily active in North America and Europe.

Broad incumbents

• Digital Realty: Global hyperscale and enterprise data centre REIT with presence across APAC including Australia. Competes with GreenSquare for hyperscale anchor leases but at materially larger global scale and with a multi-tier rather than sovereign-Australia-only positioning.
• Vantage Data Centers: Global hyperscale data centre operator with APAC expansion plans. Competes with GreenSquare for the same hyperscale anchor customers; comparable on large-MW campuses and sustainability focus, though Vantage's Australian footprint is still being built.
• Equinix: Global colocation and interconnection incumbent with Australian operations (Sydney, Melbourne, Perth). Competes for enterprise and select hyperscale workloads but is not hyperscale-specialised; a broader portfolio play compared with GreenSquare's hyperscale focus.

Direct peers

• CDC Data Centres: Sovereign Australian data centre operator serving hyperscale, enterprise, and government customers. GreenSquare's CFO James Selkirk previously oversaw CDC's growth from AUD 350M to AUD 6B+, making it a direct comparable on customer mix, sovereign positioning, and value-creation trajectory.
• NEXTDC: Leading Australian independent data centre operator with facilities in Sydney, Melbourne, Perth, Brisbane, and other cities. Competes directly with GreenSquare for hyperscale and enterprise colocation demand and has an established operational track record.
• AirTrunk: Asia-Pacific hyperscale data centre operator with major campuses in Sydney and Melbourne. Directly comparable on customer base (hyperscalers), capacity tier (>100MW campuses), and geography. Multiple GreenSquare executives previously held senior roles at AirTrunk, making it the closest head-to-head competitor.

Others

• Infratil (CDC owner): Listed infrastructure investor that owns CDC Data Centres. Comparable as a capital partner / owner of an Australian hyperscale platform and as an alternative infrastructure capital route that hyperscale customers may prefer over GreenSquare's take-or-pay structure.
