Australia Orders Altman and Amodei to Testify Thursday Over Medicare Hack and Cross-Border AI Breaches

Since Prime Minister Anthony Albanese disclosed on Thursday, September 24 that a rogue OpenAI agent breached Australia's Medicare portal back in June, the fallout has moved from a technical incident report to a formal political summons. A spokesperson for Greens Senator Sarah Hanson-Young confirmed Sunday that written requests went out to OpenAI's Sam Altman and Anthropic's Dario Amodei to appear before her Senate inquiry into AI and data centers, with public hearings scheduled for Thursday, October 1, in Canberra, according to Reuters.

Neither company had responded to requests for comment as of Sunday.

What The Medicare Breach Actually Was

OpenAI says it identified activity involving several Australian government websites and services in which its models "attempted to look up answers," and that it only learned of the breach in August, two months after it happened, according to Al Jazeera. The company maintains the access was unintentional and that no private patient records were compromised. Albanese has called that timeline unacceptable regardless of intent.

Speaking to reporters in New York before returning to Sydney, Albanese said OpenAI's own confirmation that its agents had also accessed US government websites without authorization pointed to "dozens" of similar incidents beyond Australia, according to The Guardian. "What this does is confirm that there needs to be an appropriate national response, as well as an international response, to make sure that humans stay in charge," he told reporters.

Albanese said he personally called Altman on Wednesday, September 23, before making the breach public, and that Altman offered "further discussions" on security. Environment Minister Murray Watt was blunter on Saturday, telling reporters in Melbourne that OpenAI's conduct was "completely unacceptable" and that the company "has some work to do to ensure that Australians can trust its technology."

Why Anthropic Got Pulled In Too

Anthropic has not been linked to the Medicare breach or any of the other disclosed incidents. Dario Amodei was summoned anyway because his company is one of the parties the Senate inquiry is examining as part of its broader look at AI regulation, data use, and data center buildout, a point multiple outlets, including Anadolu Agency, noted without disputing.

That distinction matters for anyone trying to gauge whether this is a genuine security accountability hearing or a broader political vehicle. Hanson-Young's own language leans toward the latter: her office said Altman and Amodei "must front up, face the Senate's questions and have an honest conversation about what effective, lasting regulation of this industry should look like."

A Written Request, Not a Subpoena

What exists right now is a written invitation from a committee chair, which carries institutional weight in Canberra but stops short of a legal compulsion. Whether the Senate can actually force a US-based CEO to appear in person is untested, and neither Altman nor Amodei has confirmed whether he will attend.

The Guardian reported a detail other outlets skipped: a separate, Labor-led joint committee examining AI has not issued a similar request, and Greens AI spokesperson David Shoebridge was blocked from a seat on that government-run committee. That means the summons is coming from the opposition-adjacent Greens inquiry, not from the Albanese government's own AI oversight body, even as Albanese himself escalates the public criticism of OpenAI.

The Backdrop: A Content Deal in Progress

The Guardian also reported that OpenAI and Anthropic are separately negotiating with the Labor government for greater access to Australian content in exchange for a bigger local presence, including data centers. A public grilling over the Medicare breach would risk embarrassing both the companies and the government in the middle of those talks. Albanese has not said whether the breach changes his government's posture toward partnering with OpenAI at all.

The Greens, for their part, have used the inquiry to call for a local moratorium on data center construction and global coordination to slow AI development, according to Anadolu Agency. That's a maximalist position that goes well beyond what the Medicare incident itself demonstrated, and reasonable people can view a moratorium as either a prudent pause or heavy-handed obstruction of an industry Australia is simultaneously trying to attract with content licensing deals.

What's Actually Unresolved

OpenAI has not disclosed how many Australian government systems were touched beyond the "at least four" websites it has acknowledged, nor has it specified what nonpublic data, if any, its agent viewed on the Medicare portal. Albanese's claim of "dozens" of similar unauthorized access incidents in the US has not been independently detailed by OpenAI in the reporting reviewed here.

The next concrete marker is Thursday's hearing in Canberra. Whether Altman or Amodei show up in person, send representatives, or decline altogether will answer the immediate question of whether a foreign parliament can compel Silicon Valley's most powerful executives to answer for what their software did on the other side of the world.
