SYDNEY, AUSTRALIA – APRIL 23: Chairman and CEO of Microsoft Satya Nadella speaks on stage during the Microsoft AI Tour at TikTok Entertainment Centre on April 23, 2026 in Sydney, Australia. Nadella, making his first visit to Australia since 2019, addressed business leaders, developers, and government representatives at the Microsoft AI Tour in Sydney on April 23, outlining a vision for Australia to become a critical hub for AI innovation rather than simply a consumer market for Microsoft’s products.

Microsoft on Thursday announced a A$25 billion ($18 billion) investment into Australia’s digital infrastructure which will see the technology giant partnering with Canberra on initiatives spanning cybersecurity, workforce upskilling, and artificial intelligence development.
Touting its “largest ever” investment in Australia, Microsoft said it would expand adoption of its Azure cloud computing infrastructure in the country by more than 140% by the end of 2029.
The partnership would also see Microsoft expanding existing collaborations with government entities like the Australian Signals Directorate — Australia’s signals intelligence agency — and the Department of Home Affairs to secure critical infrastructure, as well as training three million Australians on the use of AI by 2028.
Microsoft’s Thursday agreement builds on a previous A$5 billion commitment to Australia in October 2023, which it said at the time was its “single largest investment” in 40 years operating in the country.
“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,” Australian Prime Minister Anthony Albanese said at a press conference where he was joined by Microsoft CEO Satya Nadella as part of the Sydney leg of Microsoft’s AI tour.
Canberra has actively sought to expand the country’s AI capacity. In December 2025, the government launched its National AI Plan, which pledged to “build an AI-enabled economy that is more competitive, productive and resilient.”
Beyond Microsoft, Canberra has courted investments from other AI hyperscalers. In July, Amazon Web Services pledged a A$20 billion investment in Australia, and in December, Australia announced a A$7 billion investment from OpenAI.
Australia has touted its edge in attracting foreign AI investment, citing its “rigorous but tech-friendly” regulatory environment. The country ranked second only to the U.S. in global data center investments in 2024, according to a ranking published by Knight Frank.
Microsoft executives inked a memorandum of understanding Thursday, pledging to abide by the Australian government’s recently announced expectations of data centers and AI infrastructure development, which include commitments to prioritize Australia’s national interest, and to ensure sustainable water usage.
In March, Anthropic CEO Dario Amodei met with Albanese to sign a similar memorandum of understanding over cooperation on AI safety research, calling Australia “a natural partner for responsible AI development.”
As of October 2025, Microsoft operated three data centers across Australia, with three more under construction in Melbourne and Sydney.
The Washington-headquartered tech giant has seen its stock trading around 20% lower in recent months compared to its October 2025 highs.
At the end of March, Microsoft closed its worst quarter on Wall Street since 2008, with analysts telling CNBC the business’s struggles relate to broader market reactions to AI-driven disruptions to software stocks.
