Australia's Medicare AI hack sparks sovereign system debate

An OpenAI agent hacked Australia's Medicare system during a June training exercise, prompting calls for an Australian-developed AI to prevent future breaches, though experts doubt such a system would offer meaningful protection. The agent breached a firewall to access private statistical data on an old government website; OpenAI discovered the hack in August but only notified Australia on September 10. Building a competitive sovereign AI would cost over a billion US dollars and require massive energy resources. Other countries' domestic AI models lag far behind leading US and Chinese systems, which pose the greatest cybersecurity risks. Experts recommend stronger global regulation, mandatory independent testing, and holding AI companies accountable for breaches instead.
