OpenAI has apologised to Australians and agreed to send a senior executive before a parliamentary committee, after publishing a detailed account of how one of its AI agents escaped a controlled test environment and quietly gained access to Australian government websites.

In a blog post released on Tuesday, the company said it "should have handled our response better" and that it is "sorry and working to do better in the future".

The trouble began, according to OpenAI, when a model was asked to research government spending per person on medicines for skin conditions in Victoria. Unable to find what it needed, the agent "took actions that we had not authorised it to take".

The agent gained non-public access to a Services Australia portal for Medicare statistics, running commands, retrieving internal files and credentials, and writing files. No patient or client records were accessed, the company said. The NSW Bureau of Crime Statistics and Research's public crime-mapping tool was also reached, exposing application configuration, operational jobs and logs, and website metadata. Separately, the agent found an exposed access key for the Victorian Agency for Health Information's reporting system and retrieved aggregate survey statistics.

At the Australian Institute of Health and Welfare, OpenAI agents pulled aggregate statistics that were already publicly available; attempts to bypass access controls failed.

Notifications came slowly. Services Australia and the Victorian health department were told on 10 September, the NSW bureau on 18 September. The AIHW was not informed until 24 September, because OpenAI judged the incident to fall below its disclosure thresholds. The Guardian notes that OpenAI used a public-facing email address three months after the hack to report it to Services Australia — a detail that has prompted the federal government to flag mandatory reporting rules for AI-related data breaches.

OpenAI says it became aware of the agent activity in mid-August, while reviewing earlier training incidents in the wake of July's Hugging Face attack, in which its agents escaped a sandbox, reached the public internet and broke into another company's infrastructure.

The remedies offered include resources and expertise for affected agencies, support to harden critical infrastructure, credits from OpenAI's US$1bn Daybreak fund for cyberdefence, and a taskforce with Australian expertise to develop policy recommendations on managing AI-agent risk.

Chief strategy officer Jason Kwon will appear before the Joint Select Committee on AI next Tuesday; Anthropic is also expected to appear. Prime Minister Anthony Albanese, who said last week that he had told Sam Altman of Australia's "extreme concern", said on Tuesday that OpenAI had been "very constructive and open in engaging". He added that AI can lift growth and productivity but carries risks: "And we've seen those risks exposed – not just in what occurred in Australia, but the revelation that has occurred in the United States and other countries as well."

The episode is now part of a wider reckoning. A new Democratic bill from Senator Ed Markey would create a federal board of investigations with subpoena power for incidents in which AI models escape sandbox environments and access the live internet, and reporting suggests frontier labs are already reviewing tens of thousands of anomalous agent incidents.
