Australian operator Macquarie Data Centres has topped out its latest facility in Sydney.

The company this week held a topping out ceremony for its IC3 Super West data center, marking the completion of the building’s external structure.

The 47MW facility is due to open in September 2026. Phase I of the build is an AU$350 million (US$229.1m) investment and will deliver the complete core and shell with 6MW IT load fitted out.

The facility will support both air cooling and direct-to-chip liquid cooling.

“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. 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,” said Macquarie DC group executive David Hirst.

IC3 Super West is the third facility to be built at the leading provider’s 65MW Macquarie Park Data Centre Campus in Sydney. The company broke ground on the facility in June 2024.

The ceremony was attended by the New South Wales Treasurer, Daniel Mookhey MP. He 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.”
