Macquarie Data Centres has completed the structure of its new 47 MW AI data centre in Sydney with New South Wales Treasurer Daniel Mookhey. The topping out ceremony marks the completion of the building’s external structure and a major milestone toward its scheduled opening in September 2026.
IC3 Super West marks a ~ AUD 350m investment supporting over 2400 construction, design and fit-out jobs. Macquarie claims the facility will be the only AI capacity added in 2026 to Sydney’s north zone, purpose built to meet rising GPU demand from hyperscalers, enterprises and neoclouds.
It comes as the federal government unveiled its National AI Plan today, and on the heels of the NSW government’s newly launched Investment Delivery Authority, which aims to accelerate future technology infrastructure projects like Macquarie Data Centres’ recently announced 150MW planned site.
With all the end-state power already secured, the facility is part of Macquarie Data Centres’ 200MW development pipeline adding more AI and cloud capacity to the market.
“IC3 Super West is the next data centre in our pipeline of sites planned to add circa 200MW of AI and cloud capacity in Sydney. Demand for high-density AI infrastructure is the most significant megatrend we’ve seen in our 25 years in the data centre industry,” said Macquarie DC group executive David Hirst.
He added: “IC3 Super West, opening in Q3 2026, is purpose-built for the high-density power and liquid cooling demands of new AI technology. Sovereign data centres keep Australia competitive in the global market and are the foundation of our AI future.”
NSW Treasurer, Hon. Daniel Mookhey said: “Companies like Macquarie Data Centres keep investing, keep expanding, and keep believing that NSW can be a global home for high-tech infrastructure. And it happens because the government has chosen to take planning and investment delivery seriously.”
He added: “In the years ahead, thousands of businesses will run smarter because this building exists. Research will accelerate because this building exists. AI capability will expand because this building exists. And NSW will be more competitive – globally competitive – because this building exists.”
IC3 Super West is the third facility to be built at the leading provider’s 65MW Macquarie Park Data Centre Campus in Sydney’s north zone and is designed to support a hybrid mix of air and liquid cooling for direct-to-chip, high-density AI and cloud workloads. Phase 1 of the build is a ~AUD 350 million investment and will deliver the complete core and shell with 6MW IT load fitted out.
