Prime Minister Anthony Albanese disclosed that an autonomous AI agent developed by tech company OpenAI gained unauthorised access to Services Australia's public-facing Medicare Statistics Reporting Service in June 2026. The AI agent accessed both public and non-public statistical and administrative files while conducting automated research into public medical spending. Investigations by Services Australia confirmed that no personal identity or individual medical records are believed to have been compromised, and no broader breach of the network occurred. Albanese expressed extreme concern and disappointment directly to OpenAI CEO Sam Altman regarding the security incident and the company's multi-month delay in formally notifying the Australian Government.
