Australian data centre developer and operator GreenSquare has signed a long-term contract with NASDAQ-listed Australian AI infrastructure provider Sharon AI, an NVIDIA Cloud Partner, for the first stage of its SYD1 data centre campus in Western Sydney. Sharon AI is expected to deploy approximately 8,200 NVIDIA Blackwell Ultra GPUs at the site, with initial operations targeted for Q4 2026.
GreenSquare said the agreement anchors the first tranche of AI-ready capacity at SYD1, with initial operations targeted for the fourth quarter of 2026. The financial terms and contracted capacity associated with the agreement were not disclosed.
Sharon AI is a NVIDIA Cloud Partner and operates as an AI neocloud, providing infrastructure for organisations developing and deploying AI workloads. The company is expected to use the GreenSquare capacity for an NVIDIA HGX B300 deployment, which GreenSquare described as one of the largest publicly announced deployments of the platform in Australia.
The customer agreement provides a commercial milestone for GreenSquare as it develops a data centre portfolio across New South Wales and Victoria. The company said its broader development pipeline exceeds 1GW.
SYD1 is located in Norwest Business Park and is being developed as a 100MW-plus campus. Its first stage involves the adaptive reuse of an existing data centre building, rather than demolishing the structure and constructing a new facility.
GreenSquare said the reuse strategy has accelerated delivery while reducing embodied carbon compared with a conventional greenfield development. The company’s June sustainability assessment claimed the project retained 92 percent of the existing structural carbon, while achieving a 76 percent reduction in structural upfront carbon per square metre and a 93 percent reduction per kilowatt of IT capacity. The assessment was conducted independently by engineering consultancy TTW.
The existing building is being upgraded to support high-density computing, with GreenSquare highlighting power density and low water utilisation as design requirements. The company said the infrastructure is intended to accommodate changing customer requirements over time.
GreenSquare CEO Charles Penny said the customer commitment validated the company’s platform and demand for AI-ready infrastructure that can be delivered with speed and operational discipline. “Our focus now is on execution – bringing next-generation capacity online safely, reliably and on schedule,” he said.
In March, GreenSquare said the proposed 80MW SYD1 Stage 2 had been endorsed for support through the NSW Government’s Investment Delivery Authority (IDA). The programme provides practical, non-financial assistance, including coordination with government agencies and support in addressing infrastructure and regulatory issues.
