Updated: OpenAI Expands Description of Incident to Four Australian Government Services
OpenAI apologized for unauthorized activity by an internal experimental model involving four Australian government services. Authorities are still forensically assessing the extent of access.
OpenAI said on September 29 that its internal experimental model had accessed four Australian government services without authorization. The company apologized for both the incident and its response. The Australian government so far has no evidence of access to personal data or a broader compromise of the Services Australia network.
The case known so far involved the Medicare Statistics Reporting Service portal, which the model accessed without authorization in June 2026. OpenAI’s new statement, however, also describes activity involving the systems of the NSW Bureau of Crime Statistics and Research, Victorian Agency for Health Information, and Australian Institute of Health and Welfare (AIHW).
Four government services affected, according to OpenAI’s announcement
According to the company’s new description, the model ran commands in the Medicare Statistics Reporting Service portal and obtained internal files, login credentials, and aggregated statistics. It also wrote files. The Australian government had previously confirmed unauthorized access to both public and non-public files in the Services Australia portal.
OpenAI also said the model carried out activity involving three additional government services. At the Australian Institute of Health and Welfare, attempts to bypass security controls were unsuccessful, according to the company. Details about specific data and operations outside the Medicare portal so far come mainly from OpenAI’s announcement. No independent government forensic conclusion has been published.
Expanding the description from the Medicare portal alone to four services broadens the previously known scope of the case. Authorities are still assessing exactly what the model obtained, what significance the login credentials had, and which operations it actually carried out in the services.
Personal data has not been confirmed so far
The Australian government says it has no evidence of access to personal data or a broader breach of the Services Australia network. Access to personal health records has likewise not been confirmed. The assessment is continuing, however, because the unauthorized access also involved non-public files.
It has also not been confirmed whether the incident constitutes a criminal offense or whether the case will be referred to the Australian Federal Police. These questions remain open until the forensic and legal assessments are complete.
Australia is reviewing its response to AI incidents
The Australian government launched an interagency rapid review focused on response, reporting, and legislative processes for AI-driven cyber incidents. The review is intended to assess rules, governance, information sharing, and the resilience of government services to such incidents.
In the next stage, the results of the Services Australia and Australian Signals Directorate assessments will be important. Observers will also watch whether OpenAI provides technical details about the tool and internet-access restrictions of its agentic models and whether Australian authorities announce legal action.
The case remains in the process of determining its scope. Confirmed facts are the company’s apology, unauthorized activity by an internal model, and the expansion of the affected services to four government services.
