Top Highlights

  • GreenSquareDC's SYD1 Stage 2 development application has been endorsed by the Hills Shire Council, unlocking up to 96MW of additional AI data centre capacity in Greater Western Sydney.

  • The full SYD1 campus in Norwest will deliver approximately 110MW when complete, backed by AUD $1.2 billion from Partners Group.

  • SYDGPU1, the Stage 1 facility, is on track to deliver 15MW of liquid-cooled, high-density capacity in Q3 2026.

  • GreenSquareDC's own specifications list rack densities from 14kW to 200+kW, positioning the facility for the highest-density AI workloads in the Australian market.

  • The endorsement positions a new entrant alongside NEXTDC, Macquarie Data Centres and Goodman in the contest for Sydney's sovereign AI compute market.

GreenSquareDC, a Partners Group-backed data centre operator founded in 2022, has cleared a significant planning milestone. The Hills Shire Council has endorsed the Stage 2 development application for SYD1, the company's flagship AI data centre campus at 3 Brookhollow Avenue in Norwest, Greater Western Sydney, according to an announcement from the company. The endorsement unlocks the second and larger phase of a campus designed to deliver approximately 110MW of total IT capacity across both stages, making it one of the largest single-site data centre developments in the Sydney basin outside the established hyperscale corridors.

Stage 1 of SYD1, branded as SYDGPU1, is already under construction with Erilyan appointed as general contractor. That first phase will deliver 15MW of high-density, liquid-cooled capacity and is on track for completion in Q3 2026. Stage 2 adds up to 96MW of additional campus IT capacity, representing the greenfield expansion that transforms SYD1 from a mid-tier facility into a genuine hyperscale contender.

The company behind the campus

GreenSquareDC launched in October 2022 and acquired the former IBM/Kyndryl facility at Norwest Business Park as the foundation for SYD1. In 2025, Swiss private markets firm Partners Group acquired the company with a committed equity investment of up to AUD $1.2 billion, providing the capital base to fund construction across campuses in Sydney, Melbourne and Perth.

The Norwest Business Park location carries strategic weight. The precinct is an established hub for financial services and telecommunications tenants, and GreenSquareDC's own materials describe connectivity to Tier 1 networks including Vocus, TPG, Telstra and NextGen. For enterprise buyers evaluating sovereign AI data centre options, the existing fibre density and the precinct's established profile are material considerations.

Designed for high-density AI workloads

What separates SYD1 from many of the data centre projects currently moving through Sydney's planning pipeline is its explicit orientation toward AI-native workloads. GreenSquareDC lists rack densities from 14kW to 200+kW on its own specifications, with liquid cooling infrastructure designed into the facility from the outset rather than retrofitted. The company describes SYDGPU1 as purpose-built for GPU-dense environments, supporting rear-door heat exchange, direct-to-chip and liquid-to-liquid cooling systems.

The shift from 10 to 15kW air-cooled racks to 100kW-plus liquid-cooled racks is the defining infrastructure transition in the global data centre sector, and Australian operators are at varying stages of readiness. GreenSquareDC is positioning SYD1 to serve the high end of the density spectrum from day one, targeting GPU-as-a-Service providers, hyperscalers and AI-native tenants who require liquid cooling as a baseline rather than an upgrade.

Sydney's AI data centre competitive landscape

The Stage 2 endorsement places GreenSquareDC in direct competition with several major projects vying for Sydney's AI compute demand.

Macquarie Data Centres has described IC3 Super West as "Sydney's only new AI-ready data centre in the north zone in 2026," backed by an AUD $500 million loan facility with Phase 1 due for completion in September. Goodman has received approval for its $845 million facility at Lanceley Place in Artarmon, a six-storey development in the growing technology precinct near Gore Hill Technology Park. NEXTDC's S3 in Artarmon, with a target capacity of 80MW, has been operational since its 2022 opening.

GreenSquareDC's campus in Norwest adds a western Sydney option to a market that has historically concentrated around the North Shore and Macquarie Park corridors. For tenants seeking geographic diversity within the Sydney metro area, or for those whose power requirements are better served by western grid infrastructure, SYD1 presents a different proposition entirely.

Sustainability and the government expectations framework

GreenSquareDC's approach to sustainability aligns with the federal government's Expectations of data centres and AI infrastructure developers, released on 23 March 2026, which asks operators to ensure new projects add electricity supply rather than consuming existing grid capacity.

The company's sustainability framework, built around what it calls Five Pillars, includes low water consumption through cooling design and water harvesting, best-in-class annualised operating PUE through high-efficiency cooling equipment, low GWP refrigerants, renewable energy options for offsetting Scope 2 emissions and reduced Scope 3 emissions through repurposing the existing building shell at the Norwest site. Whether those commitments translate into measurable outcomes will depend on operational performance once the facility is live.

Timing and the broader AI infrastructure pipeline

The timing of the Stage 2 endorsement is relevant in the context of the Anthropic memorandum of understanding with the Australian government signed this week. Anthropic confirmed it is "exploring adding local capacity through third-party partners in Australia." GreenSquareDC's liquid-cooling capability and high-density design position it as a potential fit for the kind of sovereign AI compute tenants that Anthropic and other frontier AI companies are evaluating in the Australian market.

For the broader Australian data centre sector, SYD1's progression from planning approval to construction to Stage 2 endorsement within 12 months reflects the pace at which capital is moving into AI-ready infrastructure. Partners Group's $1.2 billion commitment is one of the largest private equity-backed data centre investments in Australian history, and it signals confidence in sustained demand for high-density capacity in Sydney's western growth corridor.

The connectivity piece remains critical. As we noted in our analysis of SUBCO's SMAP Hypercable, distributed AI workloads require inter-capital fibre diversity. GreenSquareDC's Norwest location, with connectivity to multiple Tier 1 carriers, positions SYD1 well for east-coast traffic. But operators pursuing national AI infrastructure contracts will need to demonstrate path resilience across all major corridors.
