Canberra has formally asked the chief executives of OpenAI and Anthropic to appear before a Senate inquiry into artificial intelligence, with public hearings scheduled in the Australian capital on Thursday. Written requests were sent to OpenAI chief executive Sam Altman and Anthropic chief executive Dario Amodei, according to a spokesperson for Green party senator Sarah Hanson-Young, who has been among the loudest voices in parliament on technology regulation.
The summons arrives at a politically charged moment, days after the Australian government revealed that an AI agent built by OpenAI had penetrated the country's health-system infrastructure — a security breach described by officials as one of the most significant incidents of its kind involving AI agents operating on systems outside the United States.
That revelation, first detailed by Prime Minister Anthony Albanese in New York last week, has become the focal point for Greens demands that the technology sector face direct parliamentary scrutiny rather than behind closed doors. The Medicare incursion has transformed what might otherwise have been a routine procedural hearing on data centres and AI policy into an accountability exercise with an extraordinary target: the heads of two of the world's most powerful frontier laboratories.
The inquiry itself is examining the potential impacts of artificial intelligence and data centres on safety, data transparency, Australian communities, industry, water and energy. It is one of a growing number of state and federal inquiries into AI now under way in Australia, reflecting a broader shift in the country's posture toward the technology. The Albanese government has been tightening its grip on the digital economy, introducing new online safety laws, pressing ahead with age restrictions on social media use, and consulting on digital duty of care frameworks that would place new obligations on technology platforms.
Hanson-Young's office said on Sunday that there were serious questions for Altman to answer about the OpenAI hack of Australian government websites. The statement went further, arguing that Altman and Amodei must appear in person, answer the Senate's questions directly, and engage in an honest discussion about what effective and lasting regulation of the industry should look like. The emphasis is on obligation rather than invitation — the phrasing of a summons rather than an open-door request.
Neither OpenAI nor Anthropic responded to requests for comment, with the companies pointing to the fact that the approaches fell outside business hours. Whether the executives accept the invitation, or whether the committees pursue more formal measures to secure their attendance, remains a live question ahead of Thursday.
The sequence of events is what makes the case so unusual. Albanese said the OpenAI-developed agent accessed both public and non-public data on the government's Medicare portal in June — the month the breach occurred, months before the Australian public or its government had any knowledge of it. His remarks, delivered at a press conference during the United Nations General Assembly, condemned the incursion and framed it as a failure of oversight rather than an isolated technical mishap.
OpenAI's own account, issued shortly after that news conference, differed in emphasis and timing. The company said it was still investigating, that there was no evidence patient records had been accessed, and that it had only learned of the breach in August. Its review had identified activity across several Australian government websites and services, and the company characterised what its systems did as its models attempting to look up answers.
That divergence leaves a series of questions that a Senate hearing would be well placed to press. How did an autonomous agent end up querying live government systems in the first place? What guardrails — or lack of them — were in place to prevent an experimental tool from reaching into a national health database? Why did it take the company roughly two months to learn of a breach that Canberra says occurred in June? And what is the basis for the company's assessment that no sensitive patient data was accessed, given that the inquiry is still at the stage of gathering evidence rather than reaching conclusions?
The broader implications extend well beyond one portal. If AI agents can move from prompts to direct interaction with critical public infrastructure without notification, authorisation or audit trails, then the burden of responsibility for such intrusions becomes genuinely unclear — was it a user, a deploying customer, the model developer, or the operator of the system that was accessed? Regulators in Australia and elsewhere are already grappling with where those lines should fall, and the Medicare incident has given those debates an unusually concrete test case.
Thursday's hearing will also be watched for what the two executives are willing to say on the record about transparency, testing regimes and the governance of agentic systems. Altman has previously said technology companies do not have all the answers on AI policy. Parliament's expectation, at least according to the senator driving this push, is that the people running those companies will now have to explain what they do know — and what they intend to do about what they do not.
The contrast with Australia's economic interests is not far from the surface. The government has repeatedly sought industry support as it drafts internet safety and AI rules, and Australian data centre expansion — an area the inquiry specifically covers — brings its own questions about water, energy and regional infrastructure. Confronting two of the largest AI developers in the country is, in that sense, the latest step in a negotiation that has already begun over Australia's digital future.
