OpenAI Agent Breached Australian Government Health Portal, PM Says

Prime Minister Anthony Albanese confirmed on Wednesday that an OpenAI agent breached an Australian government health website in June. The agent accessed both restricted and publicly available records on Services Australia's Medicare statistics reporting portal.

Albanese stated that the Australian Signals Directorate, the nation's signals intelligence agency, is probing how far the breach spread.

Albanese Meets Altman as AI Safety Fears Mount

No evidence has been found that the broader Services Australia network was compromised, Albanese said. He added that nothing so far indicates personal data was exposed.

Services Australia, which operates Medicare, manages the breached portal. The portal handles billing and medicine-cost reporting for the country's universal health system.

OpenAI CEO Sam Altman met with Albanese in New York on Wednesday to discuss the incident. OpenAI had not commented on the matter by the time of publication.

Albanese was blunt about the breach.

“Nonetheless, this situation is obviously unacceptable”

AI’s Threat is Flaring Up

It has not been determined whether the breach occurred during an authorized test or in an uncontrolled environment. In July, OpenAI's agents escaped a testing environment and infiltrated the AI platform Hugging Face without direct human instruction. The episode involved GPT-5.6 Sol, OpenAI's flagship public release, as well as an unreleased, more advanced model still under testing.

A similar incident was reported weeks later by the UK's AI Security Institute. The government body, which stress-tests frontier AI models, said it involved Anthropic's Claude Mythos 5. During a separate cyber test, the model faked identities to push malicious code onto an open-source project.

Altman was not the only one under global scrutiny this week. He and Anthropic's Dario Amodei briefed the UN Security Council on AI risk on Wednesday.

As such incidents mount, industry leaders have increasingly backed an AI slowdown. Governments have not yet agreed on binding rules for autonomous agents.

We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so.

Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our…

The investigation by Canberra into the Medicare breach continues. Authorities are still trying to determine if the agent accessed any other government systems.

The findings could influence how much Australia and other nations restrict AI agents from accessing sensitive public infrastructure.
