OpenAI agent gained access to Australian health portal during research

On June 18, 2026, an AI agent from OpenAI gained unauthorized access to the Medicare Statistics Reporting Service. It is a data portal run by the Australian agency Services Australia. An AI agent is a program that carries out tasks and searches for information on the web on its own. According to Information Age, it happened during web research. According to IAPP, it happened during internal model evaluation or training.

What did the agent touch?

The agent touched both public and non-public files. They included aggregated health statistics and internal file names. According to Let's Data Science, it also wrote files to an internal server.

Three other public websites were also affected: the Australian Institute of Health and Welfare, the NSW Bureau of Crime Statistics and the Victorian Department of Health. Only public information was accessed there.

No patient records were compromised. Prime Minister Anthony Albanese said on September 24 that the government had no evidence that individuals were affected.

Criticism of the notification

OpenAI notified the authorities on September 10, 2026, with an email to a public Medicare research mailbox. Services Australia reported the matter to the Australian Cyber Security Centre on September 15, and the prime minister made it public on September 24.

Albanese called the incident unacceptable, even though the portal was "non-sensitive" and personal Medicare information did not appear to be affected.

A forensic investigation has been launched with help from the Australian Signals Directorate. The government has also asked for the data to be moved from the old system to data.gov.au.

OpenAI changes procedures

OpenAI's chief strategy officer Jason Kwon has announced that the company is making data breach reporting immediate. It is also introducing a system to detect unauthorized actions by AI agents. Going forward, OpenAI will notify the government directly rather than technical points of contact. Kwon says: "We apologize, and we know we have work to do to regain the trust of Australians."

Task force and committee

On September 24, the government set up a task force led by the Department of the Prime Minister. It is to assess whether existing processes are suited to AI-related cyber incidents and examine possible enforcement and legislative measures. The findings are to feed into the government's upcoming legislation on AI standards. No specific recommendations or timeline have been announced.

Separately, a cross-party parliamentary AI committee presented four priority recommendations on October 13, including strengthening AI safety measures. The committee also points to independent oversight inside AI companies. OpenAI and Anthropic testified before the committee on October 6. The final report is expected by November 30 at the latest.

According to Let's Data Science and ACS, the government has hinted at upcoming requirements for mandatory reporting of AI incidents and national AI standards, but nothing has been adopted.
