Microsoft Pledges $18 Billion to Expand Cloud and AI Infrastructure in Australia by 2029
April 23, 2026
Microsoft has committed to investing AU$25 billion (approximately US$18 billion) in Australia by the end of 2029, marking one of the largest technology infrastructure pledges in the country’s history. The announcement, made by CEO Satya Nadella during Microsoft’s AI Tour in Sydney, aims to significantly expand the company’s cloud and artificial intelligence capabilities across the region.
This new commitment will increase Microsoft’s Azure computing infrastructure in Australia by more than 140 percent, building on a previous AU$5 billion (US$3.18 billion) pledge announced in late 2023. At that time, Microsoft described the earlier investment as its “single largest” in Australia over four decades of operations. The latest pledge underscores the growing strategic importance of Australia as a hub for hyperscale cloud and AI deployment.
As part of the investment, Microsoft has signed a Memorandum of Understanding with the Australian Government. Under the agreement, the company will comply with newly established expectations for data center and AI infrastructure developers. These include covering transmission and infrastructure costs linked to data centers, offering favorable terms to Australian organizations, and supporting the country’s energy transition. Microsoft has also committed to increasing its renewable energy capacity in Australia in line with its corporate goal of becoming carbon-negative by 2030.
Beyond infrastructure, Microsoft will expand its collaboration with government agencies, including the Australian Signals Directorate and the Department of Home Affairs, to strengthen the security of critical systems. The company also plans to train three million Australians in AI skills by 2028. Speaking at a press conference, Australian Prime Minister Anthony Albanese said, “We want to make sure all Australians benefit from AI. Our National AI Plan is all about capturing the economic opportunities of this transformative technology while protecting Australians from the risks.”
As of October 2025, Microsoft owned and operated three data centers in Australia and was constructing three additional facilities around Melbourne and Sydney. The company also maintains cloud regions in Canberra, New South Wales, and Victoria, leasing capacity from third-party data centers across the country. In July 2025, Microsoft signed a five-year, AU$495 million (US$324.71 million) deal with Australia’s Department of Defence for cloud computing services.
Microsoft’s latest pledge comes amid a broader wave of hyperscale investments in Australia. Google was previously reported to be considering an AU$20 billion (US$14.2 billion) investment, though concerns over high taxes for companies with a permanent establishment have slowed progress. Meanwhile, Amazon Web Services is building a dedicated data center campus for the Australian government to handle top-secret information, a project announced in July 2024. The Australian government has committed AU$2 billion (US$1.3 billion) to that system over the next ten years, developed in partnership with AWS.
The rapid expansion of cloud and AI infrastructure in Australia reflects a global trend among major technology firms to secure sovereign data capacity and support national digital transformation initiatives. As competition intensifies, Microsoft’s latest commitment positions the company to play a central role in shaping Australia’s technological future.
