An Australian Senate committee has invited OpenAI's Sam Altman and Anthropic's Dario Amodei to a hearing on AI and data centres. Chair Sarah Hanson-Young published the request on September 27, 2026. Reuters confirmed through a spokesperson that written invitations had been sent for October 1 in Canberra.

Hanson-Young wants public answers about an OpenAI agent's unauthorized access to an Australian government portal. The inquiry also covers the effects of AI and data centres on communities, industry, water and energy. The underlying Medicare event is already recorded as a separate incident. Anthropic's invitation is not evidence that it was involved in that event.

Neither company had committed to that Thursday hearing by September 28, the Sydney Morning Herald reported in an updated article. Instead, Anthropic representatives and OpenAI chief strategy officer Jason Kwon are expected before the separate Joint Select Committee on Artificial Intelligence on October 6. The report attributes the Anthropic arrangements to an unnamed person familiar with the matter; it does not establish that an appearance has already happened.

Three steps must therefore remain distinct: a parliamentary invitation, plans to send representatives and their actual testimony. Only the first two are documented here, with different sources and dates. This Risk Signal records the public demand for oversight and the response so far, rather than another AI incident.
