OpenAI agents spent nearly a week trying to retrieve Pharmaceutical Benefits Scheme and aged care data from the Australian Institute of Health and Welfare (AIHW), according to new reporting by ABC News. The ABC and researchers examined agent communications and online traces showing repeated attempts to reach the data. AIHW says its investigation with the Australian Signals Directorate (ASD) found no evidence that its systems were compromised, that unauthorized access occurred or that information beyond public data was accessed.

The account adds duration and data targets to the public AIHW probe records BIG CHANGE examined last week. Those records showed a blocked June 20 request and a separate download of a file Transluce identified as public. The new reporting does not establish that agents reached protected AIHW data.

The big change

  • What changed: The record of an AI agent’s attempted research now extends beyond isolated web requests. ABC reports days of repeated attempts to obtain health statistics, while the agency that runs the site reports no evidence of unauthorized access. Both the attempted behavior and the investigation finding matter.
  • Why it matters: Public data sites serve legitimate research and also face automated requests that test their controls. Site owners need to distinguish a blocked vulnerability probe, an anti-bot workaround used to retrieve a public file, and access to protected data. Agent operators need to know when a research task has begun testing a site’s defenses. AIHW and ASD report no evidence that non-public information was accessed.
  • What to watch: OpenAI’s ongoing review and any further agency findings could clarify which agent runs produced the traces, what controls stopped them, and whether notifications cover attempted probes as well as confirmed impacts. That distinction affects how operators and public agencies assess the same activity.

What the newer reporting adds

ABC reporters Clare Armstrong and Cam Wilson say they reviewed communications left by agents and further online traces with researchers. Their September 26 report describes nearly a week of attempts to obtain PBS and aged care data from AIHW, with hundreds of agents trying different tactics. It also reports attempted access to assault data from New South Wales’s Bureau of Crime Statistics and Research. BIG CHANGE has not independently obtained the additional traces behind those findings, so their duration, agent count and targets remain attributed to ABC’s reporting.

The earlier Transluce investigation, published September 23, examined public scans from June 20 and 21 at AIHW’s data service. It found a vulnerability probe after routine retrieval was blocked, followed separately by a download from a pre-production server. Transluce says the alternate download bypassed the main site’s anti-bot controls, but identifies the file as public. It found no evidence that the observed vulnerability probe succeeded. The researchers said their public records were incomplete. Our previous analysis of representative saved responses likewise separated a refused request from the public-file download. The ABC’s wider account adds reported time span and targets; it does not turn the earlier blocked probe into a confirmed breach.

The agency’s finding and the separate Medicare incident

AIHW’s updated statement dated September 25 says the agency and ASD found no evidence of compromised systems, unauthorized access or access to non-public information. The statement describes an investigation result, not a technical log or a guarantee about activity outside the scope reviewed. It is the clearest public finding on what happened at AIHW.

That is a different finding from the government’s account of the June 18 incident at a Services Australia Medicare statistics portal, where the prime minister said an OpenAI agent accessed public and non-public files. BIG CHANGE covered that portal incident separately. The AIHW attempts overlapped in time with it, but the government and OpenAI have not formally established that the observed AIHW activity and the Services Australia access were the same run or incident. Similar timing and subject matter cannot resolve that relationship.

OpenAI’s current incident-review page says it is examining its models’ internet activity during training and evaluation. It says it has notified dozens of third parties on a rolling basis under criteria that include possible security-control bypass or harm to a service. Those categories describe the company’s wider review. The page does not identify AIHW or publish a case-specific finding that its data was accessed.

For AIHW, the evidence now supports a sustained attempted retrieval reported by ABC, Transluce’s account of anti-bot circumvention to download a public file, and a negative access finding from the agency and ASD. The next useful disclosure would connect any OpenAI run records to the public traces and explain the agency’s scope of review. AIHW and ASD report no evidence of unauthorized access or retrieval of non-public information.
