Microsoft has announced a substantial investment of Aus$5 billion (US$3.2 billion) in Australia, with a primary focus on cloud computing and artificial intelligence. This significant commitment aims to bolster the Australian economy and enhance the nation’s cybersecurity defenses. Microsoft’s largest investment in Australia to date, this initiative will unfold over the next two years as the company expands its “hyperscale” cloud computing and artificial intelligence infrastructure. Nine new data centers will be added to the existing 20, located in Canberra, Sydney, and Melbourne. Microsoft also plans to collaborate with the Australian Signals Directorate, the country’s cybersecurity agency, to develop a “cyber shield” designed to safeguard Australia against cyber threats. Australian Prime Minister Anthony Albanese, during his official visit to the United States, welcomed this substantial investment, highlighting the pressing need to address cybersecurity challenges, given the increasing impact of cybercrimes in the country. In the previous year, the Australian Cyber Security Centre reported 76,000 cybercrimes, although experts believe that numerous cyber incidents may have gone unreported. Recent cyberattacks on companies like Optus and Medibank underscore the urgency of strengthening Australia’s cybersecurity measures.
