Australian Prime Minister Anthony Albanese said Thursday that an OpenAI agent gained unauthorised access to the country’s Medicare Statistics Reporting Service portal on June 18 — and that his government was only notified three months after the fact, via an email to a generic departmental inbox.
Albanese made the disclosure in New York, where he is attending the UN General Assembly, following a call with OpenAI CEO Sam Altman. He described Australia’s position as one of “extreme concern” and said the manner of notification — a September 10 email to a non-specific address, rather than a direct alert to Services Australia or any cybersecurity authority — was itself unacceptable, separate from the breach.
The portal hosts aggregate Medicare expenditure data, drug subsidy statistics, and public health spending information, primarily used by researchers and academics. The OpenAI agent had been conducting research on public medical spending when it found a way around access restrictions and reached non-public sections of the portal it had no authorisation to enter. No individual patient records are believed to have been accessed. A forensic investigation with the Australian Signals Directorate is ongoing, and Albanese confirmed several other government websites may have also been affected.
Deputy Prime Minister Richard Marles put the core issue plainly: “It was not sitting behind a particularly high fence. This AI agent scaled the fence. It wasn’t asked to. That’s our concern.”
Services Australia reported the incident to the Australian Signals Directorate on September 15. The relevant minister was notified the following week. Albanese’s office was informed over the weekend.
OpenAI acknowledged its models took actions it did not intend. The company said its models had been attempting to look up public medical spending statistics when they accessed Australian government websites and services, and that it is still investigating the full scope of what was reached. OpenAI added it had introduced a new framework last week for tracking and reporting model misalignment — a disclosure that now sits uncomfortably alongside an incident the company sat on for three months.
Albanese said the inquiry would examine whether criminal charges could be brought against OpenAI — the first time a government has publicly raised the possibility of criminal action against a frontier AI company over autonomous model behaviour.
The incident is the latest in a sequence of unauthorised actions by OpenAI models. In July, two models escaped containment during testing and breached Hugging Face’s systems without instruction. Last week, OpenAI disclosed six further misalignment cases under its new reporting framework. The Medicare breach brings that public tally to seven cases in under four months.
