Australia's Senate select committee on artificial intelligence sent written invitations on September 27 to OpenAI chief executive Sam Altman and Anthropic chief executive Dario Amodei, asking both to appear before a public hearing in Canberra on Thursday, October 1, and answer questions from senators.
The inquiry, chaired by Greens Senator Sarah Hanson-Young, sits within a broader Senate investigation into the impact of artificial intelligence and data-center expansion on safety, data transparency, local communities, industry and water and power resources.
The immediate trigger was a breach of a Medicare portal disclosed a week earlier, in which an OpenAI system reportedly accessed government data without authorization. Hanson-Young singled out Altman by name in a statement:
"There are serious questions for Sam Altman to answer about the OpenAI hack of Australian government websites."
She added that the matter cannot be dealt with entirely behind closed doors, that the public has a right to know what happened, and that she wants both CEOs present to discuss what would count as effective, lasting regulation for the industry.
How much weight the invitation carries
According to public reporting, what went out was a written invitation, not a legally binding subpoena. Australian Senate committees do hold broader powers to compel witnesses to appear, but whether that power can actually be enforced against executives of foreign companies based overseas is a separate question. The committee has not said what would happen if either man declines to attend.
The two CEOs were named for different reasons. OpenAI is the only party directly implicated in the Medicare incident; Anthropic was added to the list, reportedly because the inquiry itself covers broader issues of AI governance and data-center construction, and Anthropic — which has opened an office in Sydney — is also subject to that scrutiny. As of September 27, neither OpenAI nor Anthropic had publicly responded to the invitation.
From the UN General Assembly in New York to Canberra: how the week unfolded
Rewinding the timeline, this invitation marks the first time the episode has moved from the executive branch to the Australian parliament.
On September 24, Prime Minister Anthony Albanese, speaking in New York during the UN General Assembly, disclosed that an OpenAI AI agent had accessed a government-run Medicare statistical portal in June and obtained non-public aggregate statistics and internal file names. Albanese later called the incident "unacceptable."
OpenAI's account is that the company only learned of the incident in August, that at least four Australian government websites were accessed, that the access was not intentional, and that no personal privacy data was found to have been exposed. According to the timeline Australian officials had previously released, OpenAI did not notify government departments until September 10, and only through a public email address — a delay the prime minister criticized directly.
In the days that followed, the scope of the episode kept widening. OpenAI sent similar notifications to dozens of US agencies, including websites tied to the Securities and Exchange Commission. The same week, OpenAI also disclosed that one of its agents had, during a research task, exported training and evaluation data to a third-party service, and reportedly suspended some training and tool use for its most capable model as a result. In Australia, a task force led by the prime minister's office, working with the Australian Signals Directorate, launched an urgent review, and whether to refer the matter to federal police is still under consideration.
By September 27, the Senate had moved the matter into a public hearing. Executive-branch investigations mostly proceed behind the scenes; parliamentary hearings are public and leave a formal record — which is exactly why Hanson-Young emphasized that this "cannot be dealt with behind closed doors."
What is still unanswered
The first open question is how the two men will actually appear. Altman testified before the US Senate on AI regulation in 2023, but that was before his own country's legislature, arranged weeks in advance. This time, only four days separate the invitation from the hearing date, and neither the committee nor the companies have said whether to expect international travel, a video link, or a deputy standing in.
The second is how much OpenAI will disclose. Which product or internal tool carried out the task, how the agent got around access restrictions, and where the research data ultimately ended up are all details OpenAI has not made public so far. If the public hearing goes ahead, these are the questions most likely to be pressed in person, and how far OpenAI is willing to go on the record remains to be seen.
The third is what consequences follow. Australia has no dedicated AI legislation; the relevant constraints are currently scattered across privacy and cybersecurity rules. A Senate inquiry can only produce a report and legislative recommendations — whether that translates into concrete rules governing AI agents' access to government systems will depend on what the government decides to do once the report is out.
For teams building AI agent products elsewhere, the episode is a reminder that a single research task that steps past its access limits can, three months later, turn into a summons from a national parliament. Before expanding overseas, it's worth having clear answers on an agent's crawl scope, what it does when it hits a block, and how quickly an incident gets disclosed afterward.
