The investment is Microsoft’s largest-ever in Australia and builds on an A$5 billion commitment from October 2023. It includes expanding Azure AI supercomputing capacity by more than 140%, extending the Microsoft-ASD Cyber-Shield to additional government agencies, and training three million Australians in AI skills by 2028.
Microsoft has announced A$25 billion (approximately USD 18 billion) in capital and operational expenditure in Australia by the end of 2029, the company’s largest-ever commitment in the country.
The announcement was made by Chairman and CEO Satya Nadella alongside Prime Minister Anthony Albanese in Sydney on 23 April, during the Sydney stop of Microsoft’s global AI Tour.
The investment is underpinned by a Memorandum of Understanding with the Australian government, aligned with the government’s recently released expectations for data centre and AI infrastructure developers.

The headline figure comprises capital and operational expenditure across four areas. The largest component is infrastructure: Microsoft plans to expand its existing Azure AI footprint in Australia by more than 140% by the end of 2029, deploying advanced AI processors and significantly increasing local AI supercomputing capacity.
Australia currently has 29 Microsoft data centre sites across three Azure regions, the result of the A$5 billion 2023 commitment. The new investment will substantially extend that footprint.
The second component is cybersecurity. Microsoft will expand its existing Microsoft-ASD Cyber-Shield programme, a collaboration with the Australian Signals Directorate, to additional critical government agencies, and will deepen its collaboration on national resilience with the Department of Home Affairs.
Cyber-Shield was established under the 2023 commitment; its extension to more agencies signals a closer integration of Microsoft’s infrastructure with Australia’s national security architecture, a dynamic that has become common in hyperscaler deals with governments seeking sovereign AI capabilities.
The third is skills. Microsoft will train three million Australians with workforce-ready AI skills by the end of 2028, in addition to the more than one million Australians and New Zealanders it previously committed to training under the 2023 agreement.
The fourth is AI safety and governance: Microsoft will collaborate with the Australian AI Safety Institute and conduct what the company describes as an industry-first dialogue with workers on the impact of AI on employment.
EY-Parthenon analysis commissioned by Microsoft estimates that across the 2025 financial year, the company was responsible for A$36 billion in local economic contribution and sustained the equivalent of more than 186,000 full-timejobs, figures that will be cited in support of the deal’s economic case but which should be read as Microsoft-commissioned modelling rather than independent assessment.
Nadella, making his first visit to Australia since 2019, framed the investment as a bet on Australia becoming an active participant in AI-driven economic growth rather than a passive consumer of AI products built elsewhere.
Australia has also courted investments from Amazon and OpenAI, reflecting the country’s broader push to position itself as a hub for AI innovation in the Asia-Pacific. The announcement follows similar Microsoft commitments in Japan, Singapore, and Thailand.
Prime Minister Albanese said in a post on X: “More training, better technology and new opportunities for Australians to get ahead. That’s what the massive AI investment Microsoft announced today will mean for Australia.”
Albanese also noted the deal was aligned to the government’s National AI Plan, launched to capture economic opportunities from AI while managing risk.
