GreenSquare Opens Sydney Data Center Campus, Hosts 8,200 Nvidia GPUs

GreenSquare has put the first phase of its SYD1 campus in Western Sydney into operation, and the facility is already running approximately 8,200 Nvidia Blackwell Ultra GPUs for Australian AI cloud firm Sharon AI.

The site at 3 Brookhollow Avenue in Norwest Business Park reuses an IBM data center originally opened in 1995. GreenSquare delivered the conversion in eight months. Main construction works began in February 2026, with Erilyan and Fredon working on the project.

The company launched in October 2022 and Swiss private equity firm Partners Group acquired it in March 2025.

How do you convert a 30-year-old building for AI?

The answer starts with structure. GreenSquare retained the existing slab and moved the data halls to the ground floor, which allows higher-density compute without additional structural reinforcement. The company says this raised IT capacity within the original footprint by 275 percent.

The building now supports high-density AI workloads and direct-to-chip liquid cooling. GreenSquare replaced the original cooling towers with a closed-loop system that runs without evaporative cooling for roughly 96 percent of the year.

Water use drops as well. Rainwater harvesting is expected to offset about 10 percent of annual cooling water requirements, cutting reliance on potable water.

GreenSquare CTO Joshua Martens said: "We saw an opportunity to give a 30-year-old data center a completely new purpose. By rethinking the building's configuration, introducing prefabricated systems design, and using the latest technology to reduce carbon, we've created a facility that can support some of today's most demanding compute requirements while using resources far more efficiently."

What does this change for Sharon AI?

The neocloud gains Sydney capacity beyond its current footprint. Sharon, which is listed on Nasdaq and went public earlier this year, currently uses Equinix in Sydney and NextDC in Melbourne. It also partners with CDC.

The company reports 212MW of capacity online or in development, with some 64,000 Nvidia GPUs due for deployment by mid-2027. It recently bought a former paper mill in New South Wales and has a large project planned in Texas.

What comes next at the campus?

GreenSquare plans an 80MW expansion that will take the site to 110MW total.

The Sydney opening marks a shift in the company's pipeline. GreenSquare launched with plans for a Perth development in Western Australia but dropped the project earlier this year. It is now planning a large-scale development in Melbourne, Victoria.
