Microsoft amplifies AI presence in Australia with $18bn investment

Microsoft announced on Thursday a major A$25 billion (or $18 billion) commitment to enhance Australia's digital infrastructure. 

This partnership with the government focuses on areas such as cybersecurity, workforce skill development, and AI progress.

Describing it as their "largest ever" investment in the region, Microsoft aims to boost its Azure cloud services across Australia by over 140% by 2029.

This agreement will also expand Microsoft's existing partnerships with government bodies like the Australian Signals Directorate and the Department of Home Affairs to bolster cybersecurity and train three million Australians in AI by 2028.

This new agreement builds on a previous A$5 billion pledge to Australia announced in October 2023, which Microsoft described as its "largest single investment" in its four-decade presence in the country.

"We want every Australian to gain from AI advancements. Our National AI Plan aims to harness the economic potential of this transformative tech while mitigating associated risks," said Australian Prime Minister Anthony Albanese during a press meeting joined by Microsoft CEO Satya Nadella, as part of Microsoft's AI tour in Sydney.

Australia has been proactive in boosting its AI capabilities. In December 2025, the government unveiled its National AI Plan, committing to foster a competitive, productive, AI-driven economy.

Beyond Microsoft, Australia has attracted investments from other major AI firms. In July, Amazon Web Services vowed to invest A$20 billion in Australia. Following this, in December, a A$7 billion agreement was secured with OpenAI.

Australia prides itself on its attractive regulatory setting for foreign AI investments, claiming a "rigorous yet tech-friendly" environment. It ranked just behind the US concerning global data centre investments in 2024, per rankings by Knight Frank.

Microsoft leaders signed an understanding on Thursday to follow the Australian government's recently published data centre expectations, committing to prioritizing national interests and sustainable water usage.

In March, Dario Amodei, CEO of Anthropic, convened with Albanese to finalize a similar memoranda centered around AI safety research, expressing that Australia is "an ideal partner for responsible AI advancement."

By October 2025, Microsoft operated three data centers throughout Australia, with three more underway in Melbourne and Sydney.

Microsoft's stock has been trading approximately 20% lower in recent times compared to its highs in October 2025.
