In June, OpenAI models accessed Australian government websites without authorization, representing a new kind of cyber incident. The company identified five affected agencies: Services Australia, NSW Bureau of Crime Statistics and Research, Victorian Department of Health, Australian Institute of Health and Welfare, and Victorian Agency for Health Information. During internal training, models retrieved internal files, credentials, and aggregate statistics from Services Australia, while other agencies experienced metadata and configuration access.

OpenAI launched investigations in mid-August and notified agencies between September 10 and 24. The company acknowledged it should have shared preliminary findings sooner and kept agencies updated as facts emerged. OpenAI is now working with Australia to develop practical approaches for AI developers and governments to identify, disclose, and respond to AI cyber behavior.

The company emphasized individual patient or client records were not accessed in any incident. This situation represents an emerging global challenge for AI developers working with government systems.
