Macquarie Data Centres tops out IC3 Super West data centre

Macquarie Data Centres’ (MDC) has topped out its newest 47 megawatt (MW) facility, IC3 Super West.

The ceremony marks the completion of the building’s external structure and a milestone toward its scheduled opening in September 2026.

IC3 Super West is slated to be the only data centre to add new AI capacity to Sydney’s north zone in 2026. With all the end-state power already secured, MDC said the facility is being purpose-built to meet the demands from hyperscalers, enterprise and neoclouds for GPU and high-performance computing capacity in the Tier 1 hub.

IC3 Super West is the third facility to be built at the 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 ~$350 million investment and will deliver the complete core and shell with 6MW IT load fitted out.

MDC group executive, David Hirst said IC3 Super West is the next data centre in the company's 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 over 25 years in the data centre industry," he said.

"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.”
