GreenSquare signs Sharon AI deal for Sydney campus

GreenSquare has signed a long-term customer contract with Sharon AI for the first stage of its SYD1 data centre campus in Western Sydney, securing the site's first customer commitment for AI-focused capacity.

The agreement covers SYD1 Stage 1, where Sharon AI is expected to deploy about 8,200 NVIDIA Blackwell Ultra GPUs. The installation is expected to rank among the most significant announced NVIDIA HGX B300 deployments in Australia, with initial operations targeted for the fourth quarter of 2026.

For GreenSquare, the contract is an early commercial test of its Sydney campus as demand for AI computing infrastructure grows in Australia. The company is developing a broader pipeline of more than 1GW across New South Wales and Victoria.

Sharon AI, which is listed on Nasdaq, describes itself as an Australian neocloud focused on sovereign AI infrastructure. Its model is based on placing its AI Factory platform inside third-party data centre facilities so customers can build, train and deploy AI systems from local infrastructure.

The SYD1 project uses an existing data centre building rather than a new greenfield development. GreenSquare said this shortened delivery time and reduced embodied carbon, while still allowing for the high-density power requirements associated with AI systems and lower water use.

Commercial marker

The contract gives GreenSquare an anchor customer for the first tranche of capacity at SYD1. It also reflects a broader shift in the local market, as data centre operators and specialist AI infrastructure groups seek sites with enough power and the right technical design to support dense GPU deployments.

Australia has drawn increasing attention as a location for AI infrastructure because of land availability, access to power and proximity to Asia-Pacific markets. Developers and investors have responded by positioning the country as a base for regional computing demand tied to model training and inference.

The Sharon AI agreement places GreenSquare in that market as it moves from development to delivery. The business is backed by programmes managed by Partners Group.

Charles Penny, Chief Executive Officer of GreenSquare, described the customer signing as an important moment for the company as it advances its first Sydney project.

"Securing this customer commitment is an important milestone for GreenSquare. It validates our platform and the demand for AI-ready infrastructure that can be delivered with speed, density and operational discipline. Our focus now is on execution - bringing next-generation capacity online safely, reliably and on schedule," Penny said.

Local build-out

The deal also highlights the role of colocation in the AI market, where specialist AI operators can rely on established data centre campuses for physical infrastructure. This model can reduce the time needed to bring new GPU clusters online compared with building a stand-alone facility.

GreenSquare said reusing an existing building will help it meet customer demand faster in Western Sydney, one of Australia's main digital infrastructure corridors. The site is also being designed to support changing customer requirements as AI hardware drives greater power density in data centres.

Sharon AI's planned deployment adds another example of sovereign AI infrastructure being developed in Australia rather than offshore. The issue has gained prominence as businesses and public sector organisations consider where sensitive data should be processed and stored when using AI systems.

The companies have not disclosed the financial terms of the contract. They have outlined the scale of the planned GPU deployment, however, providing an indication of the size of the first stage at SYD1 and the type of customer GreenSquare aims to attract.
