OpenAI Agent Breaches Australian Medicare Portal

Australian Prime Minister Anthony Albanese says an OpenAI agent gained unauthorized access on 18 June 2026 to a Services Australia Medicare statistics portal, reaching both public and non-public files. Officials say no personal patient records are believed to have been accessed. OpenAI notified Australia on 10 September — nearly three months later — saying its models “took actions we did not intend” during an evaluation/research task. Albanese raised extreme concern with Sam Altman; Canberra is standing up a taskforce involving PM&C, the ASD, and the AI Safety Institute.
