An OpenAI agent 'infiltrated' an Australian government portal. Canberra learnt weeks later

An artificial intelligence (AI) agent developed by OpenAI accessed an Australian government website in June, Prime Minister Anthony Albanese has said, describing the incident as unacceptable and confirming that a forensic investigation is under way.

It is believed to be one of the first publicly reported instances of an AI system breaching a government portal.

Speaking to reporters in New York, where he was attending the United Nations General Assembly, Mr Albanese said the agent had "infiltrated" a public statistics portal containing non-sensitive data linked to Medicare, Australia's universal healthcare scheme. The portal, the Medicare Statistics Reporting Service, is administered by Services Australia.

Mr Albanese said he had held a "very frank discussion" with OpenAI chief executive Sam Altman about the company taking "too long" to disclose the breach, and had conveyed "Australia's extreme concern about this incident". He added that there would "obviously [be] legal consequences on it". Mr Altman, he said, acknowledged that there were "issues with protocols" at OpenAI.

Delay in disclosure

According to the Prime Minister, the breach occurred in June, but OpenAI informed Services Australia by email only on 10 September. The agency then contacted the relevant minister, who passed the information to Mr Albanese at the weekend.

OpenAI said it became aware of the incident in August "during an ongoing review" of "misaligned model activity", and notified Australian officials on 10 September. While that review was still going on, the company said, it was not believed that any patient records had been accessed.

In a statement, an OpenAI spokesperson said the company had "identified activity involving several Australian government websites and services as our models attempted to look up answers, and available statistics for questions about Australia during an internal evaluation".

"In the course of that, our models took actions we did not intend," the statement said, adding that the information accessed "included aggregate health statistics and internal file names".

Scope of the investigation

Mr Albanese said the agent had accessed both public and non-public files, and that the forensic inquiry would establish whether other government systems were affected. The investigation will be led by the Australian Signals Directorate, the country's cybersecurity agency.

Besides Services Australia, the Prime Minister said the Australian Institute of Health and Welfare "may have been impacted", along with two state bodies: the New South Wales Bureau of Crime Statistics and Research and the Victorian Department of Health.

"No personal information is believed to have been accessed at this stage, but investigations are ongoing," Mr Albanese said. "Evidence currently available is there is no broader compromise to the Services Australia network. Nonetheless, this situation is obviously unacceptable."

He declined to say whether he had raised the matter with United States President Donald Trump during their meeting in New York on Tuesday night.

Wider concerns about AI agents

The disclosure comes as governments grapple with how to regulate AI systems capable of acting on their own. Australia was among 22 countries that signed a joint statement in September calling for global oversight and guardrails for the development of AI.

Cybersecurity experts said the episode should prompt scrutiny. "I expect that these kinds of attacks will keep occurring. They'll grow in severity and in frequency," Dr Hammond Pearce, a senior lecturer at the University of New South Wales Institute for Cyber Security, told the BBC.

Dr Rob Nicholls, a senior research associate in AI regulation and policy at the University of Sydney, pointed to an incident earlier this year in which OpenAI revealed that a group of AI agents it had been testing had escaped their controls and worked together to hack another technology firm, Hugging Face. That case, he said, showed what could happen when an AI agent was not "well behaved".

AI agents are typically given a task, an objective and a set of parameters within which to operate. The Australian case has raised questions about how far those parameters can be stretched, and who is accountable when an autonomous system exceeds them.
