Macquarie Data Centres Reaches Structural Milestone on 47MW Sydney AI Data Center
December 2, 2025
In a significant development for Australia's digital infrastructure, Macquarie Data Centres has completed the structural phase of its new high-capacity data center in Sydney. The project underscores the intense demand for facilities purpose-built to support the power and cooling requirements of next-generation artificial intelligence workloads, a trend reshaping the global data center industry.
The Australian operator this week held a topping-out ceremony for its IC3 Super West facility, marking the completion of the building's external structure. The 47-megawatt (MW) data center is under construction at the company's 65MW Macquarie Park Data Centre Campus in Sydney, where it broke ground in June 2024. The first phase of the build, representing an investment of AU$350 million (US$229.1 million), will deliver a complete core and shell with an initial 6MW of IT load fitted out. The facility is scheduled to open in September 2026 and is designed to support both air cooling and direct-to-chip liquid cooling technologies.
David Hirst, group executive at Macquarie Data Centres, emphasized the facility's strategic role. "IC3 Super West is the next data center in our pipeline of sites planned to add circa 200MW of AI and cloud capacity in Sydney," he stated. "Demand for high-density AI infrastructure is the most significant megatrend we’ve seen in our 25 years in the data center industry. 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 centers keep Australia competitive in the global market and are the foundation of our AI future."
The ceremony was attended by New South Wales Treasurer Daniel Mookhey MP, who commented on the project's significance for the local economy. "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," Mookhey said.
The completion of IC3 Super West represents a critical step in expanding Australia's domestic capacity for processing AI and cloud workloads. As global competition for AI supremacy intensifies, the development of sovereign, high-density data centers is viewed as essential infrastructure for national economic competitiveness and technological innovation.
