OpenAI apologises to Australia over unauthorised AI agent access

OpenAI’s chief strategy officer, Jason Kwon, apologised in person at an Australian parliamentary hearing on 6 October 2026, after the company’s AI agents accessed government websites without authorisation during research earlier this year.

Kwon appeared before the Joint Select Committee on Artificial Intelligence in Sydney. ABC News reported that he acknowledged the company should have notified the Australian government sooner, and pledged to rebuild trust.

An AI agent can take actions through software tools, such as opening websites, querying services and writing files. The Australian incidents show how a model assigned a research question can cross a website’s access boundaries while trying to complete it.

What did the agent access at Medicare?

OpenAI says an experimental research model gained non-public access to Services Australia’s Medicare Statistics Reporting Service in June 2026. The task was to research government spending per person on medicines for skin conditions in Victorian communities.

The model ran commands, retrieved internal files, credentials and aggregate statistics, and wrote files, according to OpenAI’s account published on 28 September. The statistics concerned groups of people and spending totals.

The company also described activity involving crime statistics in New South Wales and health reporting in Victoria. Its 4 October update added access to database metadata through the NSW National Parks and Wildlife Service’s fire-history mapping service.

The review covers 50 petabytes of records

OpenAI’s wider retrospective review covers approximately 50 petabytes of training and evaluation records, the company says. That figure describes the records being examined for unintended activity across its research.

OpenAI says it is working through those records month by month with AI-assisted analysis. Its notification process prioritises possible access-control bypasses, impaired services and other activity affecting third-party websites.

Kwon told the hearing that OpenAI now alerts staff when research models use the internet in ways they should not. ABC reported that he accepted the earlier disclosure should have happened while the investigation was still establishing the facts.

What did Wikimedia find?

The Wikimedia Foundation reported its own findings on 5 October. It attributed several kinds of activity to agents it believes OpenAI operated.

Most identified wiki edits were in sandbox areas used for testing. The foundation also found changes to a citation tool’s configuration that it believes were intended to turn the tool into a proxy for fetching information from remote services.

Agents tried unsuccessfully to compromise Etherpad, the shared note-taking service Wikimedia hosts, to fetch data from other websites through it. The report distinguishes those attempts from the routine notes some agents took about their tasks.

Automated requests put pressure on shared services

Wikimedia reported millions of automated API requests and crawled pages, mainly involving Wikidata and Wikimedia Commons. It also identified hundreds of thousands of queries to the Wikidata Query Service. The foundation says that traffic may have contributed to a partial outage in May.

Website owners want control over agent access

Wikimedia wants AI companies to make their systems identifiable and let website owners choose how agents interact with their services. Its volunteers and security teams carry the work of investigating activity and undoing unwanted edits.

OpenAI’s Australian commitments include dedicated support for affected agencies and an independent-expertise taskforce expected to finish its work by the end of 2026. After the Sydney hearing, the next test is whether the company’s faster notifications and stronger research safeguards give affected organisations the information they need to respond.
