Huntingwood datacentre project overview
Microsoft Datacentre (Australia) Pty Limited (“Microsoft”) is proposing the development of a new datacentre at Huntingwood in Western Sydney.
Datacentres provide the digital infrastructure that supports cloud computing, online services, AI, government services, businesses, schools, and healthcare providers. They enable the storage, processing, and delivery of data used every day by people and organisations across Australia.
Microsoft is investing in datacentre infrastructure in Australia to help meet growing demand for cloud and AI services while supporting Australia’s digital economy.
About the project
The proposed Huntingwood datacentre forms part of Microsoft’s broader investment in digital infrastructure across Australia.
The facility has been designed to support cloud and AI services while meeting applicable planning, environmental, and regulatory requirements. As with all Microsoft datacentres, the project will be subject to applicable assessment and approval processes at both state and federal levels.
