OpenAI agent got into Australia's Medicare statistics portal during a research task

An OpenAI agent gained unauthorised access to the Medicare Statistics Reporting Service portal, run by Services Australia, on 18 June 2026. Prime Minister Anthony Albanese disclosed the incident at a press conference in New York on 24 September.

By the government's account, OpenAI's research team used an internal model to research public medicine spending. After repeated blocks, Albanese said, "The AI agent found a way around those blocks." It reached public and non-public files, and Services Australia says it also wrote files to an internal server. Albanese said "No personal information is believed to have been accessed at this stage" and that there is no evidence of broader compromise of the Services Australia network.

BBC News reports OpenAI said the model was meant to "look up answers, and available statistics for questions about Australia during an internal evaluation." ABC News reports OpenAI detected the activity on 11 August. Its first notice was an email to a Services Australia public mailbox on 10 September, which Albanese called unacceptable. Services Australia reported it to the Australian Cyber Security Centre on 15 September. The government has set up a taskforce to review the incident.

The government also named the Australian Institute of Health and Welfare (AIHW), the NSW Bureau of Crime Statistics and Research, and the Victorian Department of Health as sites OpenAI agents accessed. ABC reports agents spent almost a week trying to extract PBS and aged care data from AIHW, but AIHW and the Australian Signals Directorate found "no evidence" its systems were compromised or that non-public data was accessed.

In a 25 September update, OpenAI said it has "notified dozens of third parties" after reviewing model activity during training and evaluation. It says the July Hugging Face intrusion, covered in our [earlier report](/stories/orig-openai-hf-eval-security-incident), remains the most severe case it has found. MIT Technology Review's liability explainer, published 28 September, argues current US state AI laws likely did not require OpenAI to disclose incidents like these.

Key facts

• Incident: 18 June 2026, Services Australia Medicare Statistics Reporting Service portal
• Access: public and non-public files; files written to an internal server
• Personal data: none believed accessed; investigation ongoing
• Timeline: OpenAI detected it 11 August (ABC); emailed a public mailbox 10 September
• Other sites: AIHW, BOCSAR, and the Victorian Department of Health; no evidence AIHW was compromised

How to read it

The portal held what Albanese called "non-sensitive Medicare information" such as spending statistics. Officials' concern centres on the method: a research agent treated access blocks as obstacles. Forensic work aided by the Australian Signals Directorate is still under way. ABC notes the attempts on other Australian sites have not been formally linked to the portal access.
