In a remarkable shift, Sydney’s data centre market is on the rise, evidenced by a drop in the vacancy rate from 9% to a striking 5.2%. This shift emphasizes the city’s growing stature as a regional hub for data centres, as highlighted in a recent report by Cushman and Wakefield. Even without significant increases in operational capacity during the first half of 2025, robust fundamentals are sustaining the market’s upward trajectory.
The report notes that sustained demand for cloud services and artificial intelligence (AI) workloads has been a key driver of this decline in vacancy rates. The development pipeline remains vibrant, with new players entering the data centre landscape. Notably, ISPT, a major real estate investment firm, has submitted plans for a 170MW data centre in North Ryde, reinforcing Sydney’s appeal as a strategic centre for data management.
Adding to the momentum, Macquarie Data Centres has initiated a deal to acquire a land parcel in Sydney valued at US$157 million, slated for a potential 150MW data centre campus. Meanwhile, Stack Infrastructure, with an eye on the future, is planning a substantial 450MW campus at Erskine Park, backed by an investment of US$405.3 million—one of the largest single-site developments in Sydney’s history. This isn’t just a case of numbers; it’s a multifaceted strategy where the data centre sector is becoming as enticing as a new flavor of bubble tea in downtown Sydney.
In a notable move, Partners Group has expanded its footprint by not only acquiring Digital Halo in Singapore but also GreenSquareDC in Australia for a hefty US$759 million. This investment signifies a commitment to establishing GreenSquareDC as a forward-thinking data centre platform, tailored to meet the burgeoning demands of hyperscalers and AI.
Moreover, in the connectivity sector, Vocus Group is set to acquire TPG Telecom’s fibre infrastructure assets, alongside its Enterprise, Government, and Wholesale (EG&W) business. The Australian government has approved this US$3.42 billion acquisition, expected to finalize by year-end, marking a significant consolidation in the telecom landscape.
Cloud adoption continues to accelerate across industries in Australia. The Commonwealth Bank of Australia recently completed its migration to Amazon Web Services (AWS), heralding a new era of digital capabilities. Similarly, the Department of Defence has signed a five-year, US$324.71 million contract with Microsoft for cloud services, further solidifying partnerships within the tech ecosystem. CareSuper, a leading superannuation fund, is also transitioning its applications and data to Microsoft Azure.
In conclusion, Sydney’s data centre market not only remains resilient but is also dynamically evolving, driven by strong demand, strategic investments, and an ongoing digital transformation across various sectors.
