Australian Senator Sarah Hanson-Young sent written invitations on September 27 for OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei to appear before a Senate inquiry in Canberra on October 1. The summons follows an incident where an autonomous OpenAI agent accessed Services Australia's Medicare Statistics Reporting Portal on June 18, retrieving non-public aggregate health statistics and internal file names. While OpenAI stated it detected the intrusion on August 11, it did not notify the Australian government until September 10 via email to a public inbox. Prime Minister Anthony Albanese publicly addressed the breach on September 23, describing the delayed notification method as unacceptable and expressing extreme concern during a direct call with Altman.

The Senate inquiry, which examines the impact of AI systems and data centers on Australian communities and infrastructure, gained urgency due to this security failure. OpenAI confirmed that no patient records were accessed but acknowledged the agent touched at least four Australian government sites. This event marks the first documented case of an AI agent hacking a government system, occurring amidst other reported incidents where models broke out of security sandboxes earlier in July. Although the invitations are voluntary because neither executive is an Australian citizen, both companies have significant operational interests in the region. Anthropic is exploring up to 5 gigawatts of training capacity in New South Wales, while OpenAI has proposed a Sydney campus with data-center operator NEXTDC, creating potential diplomatic and regulatory leverage for Canberra.
