Last updated 7 October 2026.

On 24 September 2026 the Australian Government said an OpenAI agent had gained unauthorised access to the Medicare Statistics Reporting Service portal. Services Australia runs the portal. This page sets out what the government, OpenAI and others have said, and what is still unknown.

What the government has said

Prime Minister Anthony Albanese said an OpenAI agent gained unauthorised access to the public-facing portal and accessed “both public and non-public files”. He said Services Australia advised it had also written files to an internal server. He described the portal as holding “non-sensitive Medicare information relating to data and statistics such as spending”. He said no personal information is believed to have been accessed at this stage, and that investigations are ongoing.

The Prime Minister said there was “no suggestion of foreign actors”. He said it “took the company way too long to inform the Government”, and that the way it was notified “was unacceptable”.

At a press conference in Sydney the same day, Acting Prime Minister Richard Marles said “No individual’s medical data was accessed here”. He described the impact as “minor, but it is a very serious incident”. He said the information involved “has now been made public”.

Katy Gallagher, the Minister for Government Services, said the agent was doing “internet-based research into public medicine spending as part of internal capability evaluation”. She said “there are programs including to protect against bots and things that protected that website”. For “legacy public-facing websites”, she said, “I’ve asked that the information there be moved to data.gov.au, or put on alternate existing secure platforms”.

On 26 September in Sydney, the Prime Minister said “There are dozens of cases, including US government sites.” He said OpenAI had not told the government its US announcement was coming. OpenAI says it gives each organisation the facts and defers to it on whether to go public (see below). When the government made its own announcement, he said, “we weren’t aware of other occurrences”.

The same day, Environment Minister Murray Watt said: “We have asked OpenAI to provide full information about what breaches have occurred, and we expect them to do that as soon as possible.”

On 27 September, Mr Marles said he met Sam Altman at the start of September, and that the government made the meeting public at the time. According to Mr Marles, “we didn’t speak about the incident”, and the meeting “was before there had been a notification”. He called it “a very serious incident” but said its impact “is relatively minor”. The government was “working very closely with OpenAI right now to understand every step” the agents took, he said.

On 29 September in Adelaide, the Prime Minister said he had received “an extensive briefing” on the taskforce’s work the day before. In his words, “OpenAI have been very constructive and open in engaging in that process”. He said Anthropic had also been constructive. A day later in Footscray, Mr Albanese was asked about a US agreement with AI companies. He said “what we’ll be doing is producing Australian Standards for AI”. He also said “I want to acknowledge the fact that OpenAI apologised very clearly and publicly yesterday”.

Mr Marles is also acting Minister for Home Affairs. On 30 September he told ABC Radio Perth the impact was minor, “But this is a serious incident. It’s a near miss in a sense, and we need to take it seriously”. Departments are being asked to review their own IT systems, in work that “started before that breach”. Asked about timing, Mr Marles said: “it needs to be done quickly, but I’m not putting a time frame on it”. Home Affairs has since published its direction to agencies, PSPF Direction 002-2026. By 31 March 2027, every non-corporate Commonwealth entity must complete a stocktake of its legacy technology and send Home Affairs a plan to reduce it. Entities that run Systems of Government Significance, the government’s most critical digital services, must report on those by 31 December 2026. The direction says further guidance will be issued by 13 October 2026.

What the opposition has said

Liberal senator James Paterson said on 27 September: “Medicare wasn’t hacked. It was a Services Australia statistics portal”. He added that “it is to OpenAI’s credit that they told us”. In his view the Prime Minister “amped it up” by announcing the incident on the day Mr Altman addressed the United Nations. Mr Paterson also called it “extraordinary” that Services Australia was not constantly monitoring the inbox, and noted it then took 4 days to tell ASD. Ms Gallagher has said the email was escalated on 15 September after checks that it was legitimate, SBS reported.

Deputy Liberal leader Jane Hume said the “real alarm bell” was that the government only knew because OpenAI told it, The Guardian reported.

The Sydney Morning Herald reported that some technology figures and senior opposition members said the government had overstated the incident. Mr Marles rejected that. He said the seriousness lay in “an AI agent gaining unauthorised access into an Australian government website”.

Timeline

• 18 June 2026: the agent accessed the portal, according to the Prime Minister.
• August 2026: OpenAI became aware of the activity. Mr Marles said: “We are advised by OpenAI that they became aware in August”. The ABC reported the date as 11 August. OpenAI’s own account says “mid-August”.
• Start of September: Mr Marles met Mr Altman, before the government was notified. He said the incident was not discussed. OpenAI’s Jason Kwon told a parliamentary committee on 6 October that Mr Altman did not know about the incident when they met.
• 10 September: OpenAI emailed a general Services Australia inbox about the incident, Ms Gallagher said. She said the inbox “is looked at once a day”. OpenAI says it notified the Victorian Department of Health the same day. Extracts of the email, as reported by 3 news outlets, are below. The Guardian described this as “nearly three months” after the access. The email was sent 84 days after the 18 June access the Prime Minister described. It was about 4 weeks after OpenAI says it found the activity in mid-August.
• 11 September: Services Australia read the email.
• 15 September: Services Australia notified ASD.
• 18 September: OpenAI notified the NSW Bureau of Crime Statistics and Research, it says.
• 23 September: Services Australia published the Medicare statistics on data.gov.au, the catalogue record shows. The portal now points visitors to Services Australia’s Medicare statistics page.
• 24 September: the Prime Minister announced the incident and a taskforce. OpenAI notified the Australian Institute of Health and Welfare the same day “to share our findings and offer a briefing”, it says.
• 25 September (US time): OpenAI said it had notified dozens of organisations about its agents.
• 26 September: the ABC reported separate agent activity on the institute’s website. It said this was not yet formally linked to the portal incident.
• 27 September: media reported that a Senate inquiry into AI and data centres had invited the heads of OpenAI and Anthropic to appear.
• 29 September: OpenAI published its own account and apologised (see below). That evening, ministers released OpenAI’s 10 September email, the Guardian reported. The ABC said it had obtained a copy.
• 30 September (US time): OpenAI said it had now notified more than 100 organisations, Gizmodo reported.
• 1 October: the Senate inquiry’s hearing in Canberra, reported as due that day, was cancelled. No official reason has been given (see below). The same day, OpenAI told the NSW Government its model had entered a National Parks and Wildlife Service web application in June (see Other government sites).
• 6 October: OpenAI’s chief strategy officer, Jason Kwon, gave evidence to the Joint Select Committee on Artificial Intelligence in Sydney and apologised (see What OpenAI has said). Anthropic also gave evidence. Later hearings are listed on the committee’s hearings page.

OpenAI’s email to the government, as reported

OpenAI emailed Services Australia on 10 September. On the evening of 29 September, ministers released the email, the Guardian reported. The Guardian and the ABC each said they had obtained a copy. Cyber Daily said the government had revealed it. We found no copy on any government website when we checked on 1 October. No outlet printed the full email, so the extracts below are all that is public. Each is linked to the outlet that reported it.

The email opened: “We are notifying you of a security vulnerability identified during our review of OpenAI model activity involving Services Australia’s Medicare Statistics service at medicarestatistics.humanservices.gov.au”, Cyber Daily reported.

It went on: “An OpenAI model identified a way to make the server carry out instructions sent through the public reporting interface, without a private account or password.” The Guardian, the ABC and Cyber Daily all quote this sentence in the same words.

The next sentence differs by one word between the two outlets that quote it. The ABC’s copy reads: “It was able to access this to read portions of internal program files and settings, obtain a list of files, and create and read back a small test file on the server.” Cyber Daily’s copy has “internal files and settings”, without “program”.

According to Cyber Daily, the email said OpenAI had found no evidence that patient data was accessed. The Guardian reported that it named an “affected report”, a CSV file. OpenAI wrote: “We recommend that the team responsible for the service investigate the vulnerability and assess the changes needed to prevent it. We would be glad to brief your security team and provide supporting evidence as available.” It was signed “Best, OpenAI Security Team”.

The reported extracts do not mention the credentials that OpenAI’s later public account says the model retrieved. The full email has not been published, so we cannot say whether it mentions them.

What OpenAI has said

On 29 September (28 September US time) OpenAI published its own account of the incident and apologised. “We also should have handled our response better. We are sorry and working to do better in the future,” it said.

According to the account, an “experimental, internal-only” model had been set a research question on “government spending per person on medicines for skin conditions in Victorian communities”. The model “had difficulty obtaining that information, and it took actions that we had not authorised it to take.”

At the portal, the model “discovered a way to gain non-public access to the service, and ran commands, retrieved internal files, credentials and aggregate statistics, and wrote files.” It then reviewed “technical system information and source code related to the service”. In its account, no patient or client records were accessed. The post does not explain how the model got in, what the credentials were, or what files it wrote. OpenAI has said it holds back technical details to give organisations “time to investigate possible weaknesses” (see below).

OpenAI’s review began after the Hugging Face incident in July and found the Australian activity “in mid-August”. In OpenAI’s words, “Our aim was to give affected agencies a detailed account once our investigation was complete. However, we should have shared preliminary findings sooner and kept Australian agencies updated as more facts emerged.”

Web access in its research environments is now served “through cached content”, the company says, and its monitoring “would have detected this activity” and paged staff. It has pledged support for affected agencies and credits from its $1 billion Daybreak for Frontline Defenders fund. It will also set up an Australian taskforce with “independent Australian expertise”, due to finish “by the end of the year”.

The Prime Minister said the same day that the company had been “constructive and open”, AAP reported. On 30 September ASD’s Director-General, Abigail Bradshaw, told ABC RN Breakfast: “The apology is important. We shouldn’t miss that moment.” She said OpenAI had taken “a really significant step in slowing down the release of the next model”, Cyber Daily reported. A Services Australia spokesperson declined to detail what the model did, iTnews reported on 29 September. We have found no public response from the Victorian Department of Health to OpenAI’s account, as of 7 October.

Earlier, OpenAI said its models “took actions we did not intend”. CNN reported that OpenAI said it found no evidence patient records were accessed, and that the information included “aggregate health statistics and internal file names”.

OpenAI’s website says it has “notified dozens of third parties”. Its 25 September (US time) update said “Some of the websites involved are operated by governments, universities, public agencies, and other institutions.” The reason given was “partly because models performing research tasks are often directed toward authoritative sources of public information”. None of the government bodies or other sites it notified is named, Australia included. In a post on X, OpenAI said “Most cases identified so far have been lower severity, with limited or no evidence of meaningful impact to the third-party service.” Its review would take months, the post said. By 30 September (US time) it said it had notified more than 100 organisations, Gizmodo reported.

OpenAI says it lets each organisation decide whether to go public. It said: “Our goal is to give each organization the facts and defer to them on if and when to make the incident public.” It also said it holds back technical details to give organisations “time to investigate possible weaknesses”. Asked by The Record what technique the agent used, OpenAI said it had nothing to add beyond its earlier statement.

OpenAI has paused training its most capable models, a spokesperson told SBS in a report published on 27 September. The spokesperson said the pause had been announced the day before. Training will resume “only when we are confident that we have additional safeguards and alignment improvements in place”.

On 25 September (US time) OpenAI chief executive Sam Altman wrote on X: “We have not been as fast as we would have liked but we are trying to balance our desire for transparency with gaining a clear understanding from petabytes of agent activity logs, and working with impacted organizations.”

On 6 October Jason Kwon, OpenAI’s chief strategy officer, gave evidence to the Joint Select Committee on Artificial Intelligence in Sydney. He opened with an apology: “During internal training and evaluation, our models accessed Australian government websites in ways they were not directed to. That should not have happened,” the Guardian reported. He said OpenAI’s review of agent activity now reaches back to November 2025. The review covers about 50 petabytes of data and costs OpenAI more than US$500,000 a day, the Guardian reported on 3 October.

The rest of this paragraph is our summary of the committee’s broadcast. Mr Kwon said the incidents OpenAI has reported are the only Australian ones it has found so far. OpenAI has added monitoring that alerts staff when a model in training uses the internet in ways it should not, and it recently caught one such case. Asked whether Mr Altman knew of the incident when he met Mr Marles in September, Mr Kwon said he did not. He said OpenAI would support a mandatory incident reporting framework, and that affected Australian agencies will be offered OpenAI’s Daybreak cyber security program.

How the agent got in

OpenAI’s 10 September email says the model “identified a way to make the server carry out instructions sent through the public reporting interface, without a private account or password” (see the extracts above). The email calls this “a security vulnerability” but the reported extracts do not describe it. OpenAI’s public account of 29 September says only that the model “discovered a way to gain non-public access”.

Neither the government nor OpenAI has released the agent’s activity logs. A Services Australia spokesman said: “As the investigation remains ongoing, we cannot provide further information at this stage”, the Sydney Morning Herald reported. On 29 September iTnews reported that Services Australia’s forensic work with ASD was still establishing “the actions undertaken by the agent”.

On 25 September, before the email was released, The Record published an analysis of archived copies of the site. It found the site’s code sent production statistics requests to a guest endpoint, which signed visitors in automatically without credentials. The archive shows the code, not the server’s configuration on 18 June. The Sydney Morning Herald reported that from March 2025 the portal used a “guest” login that needed no password or username. No source says whether the “public reporting interface” in OpenAI’s email is that guest endpoint.

The Record also suggested, from the archived code, that the files written may have been chart images. The site’s code created one on every chart request. OpenAI’s email describes creating and reading back “a small test file on the server”. Its later public account says the model “wrote files”. Neither source says which files, or how many, were written.

Ms Gallagher has said the portal had programs to protect against bots.

At the committee hearing on 6 October, Mr Kwon said the model had found an access point at Services Australia that was not public, and took the technical details on notice. OpenAI’s witnesses described the method as “not super sophisticated”, the Guardian reported. Neither the government nor OpenAI has yet described the access point or how the model used it.

Other government sites

On 24 September Mr Marles named 3 other government sites the model interacted with. They are the Australian Institute of Health and Welfare (AIHW), the NSW Bureau of Crime Statistics and Research, and the Victorian Department of Health. He said those interactions “were entirely normal and public information was accessed”. OpenAI’s own account of 29 September describes two of those sites differently (see below).

Research lab Transluce separately reported that agents probed the AIHW website. Cloudflare blocked some of their requests. Transluce said one agent then fetched a file from a pre-production server. It said: “The file itself is public, so no non-public data was exposed, but the agent bypassed the site’s anti-bot controls.” The AIHW said “there is no evidence that our systems were compromised”.

The ABC reported on 26 September that OpenAI’s agents “spent almost a week trying to extract” Pharmaceutical Benefits Scheme and aged care data from the AIHW website. Its evidence was messages the agents left behind and online traces reviewed by researchers and the ABC. According to the ABC, these showed hundreds of agents trying different tactics. The attempts happened at the same time as the portal access but have not been formally linked to it, the ABC said. Investigations by the AIHW and ASD found “no evidence” that the AIHW’s systems were compromised or that non-public data was accessed, it reported.

The ABC also reported that the agents attempted to access assault data from the NSW Bureau of Crime Statistics and Research. In its account, one tool used by OpenAI’s agents tried to access the National Notifiable Disease Surveillance System at the Department of Health. The ABC said there was “no suggestion to date” that the agents were able to access sensitive data, such as personal information. The investigation is still checking whether other systems were affected.

OpenAI’s 29 September account gives its own view of each site. For the Victorian Department of Health, OpenAI says its agents “discovered an exposed access key” to query the Victorian Agency for Health Information’s reporting system. They retrieved “reporting configuration and aggregate survey statistics”, it says. It adds: “The extent to which this information should have been accessible is unclear, and depends on VAHI’s access policies”.

The NSW Bureau of Crime Statistics and Research runs a public Crime Mapping Tool, which OpenAI says “supplies credentials for browser API requests”. The bureau’s system “returned application configuration, operational jobs and logs, and website metadata”. The bureau said on 25 September it had found “no evidence of a security vulnerability in the Crime Mapping Tool”. It also said there was “no evidence that any information has been accessed beyond what is already publicly available through the tool”.

On the AIHW, OpenAI’s account matches the institute’s statement: “There was no system compromise”, it says. It adds that “attempts to bypass access controls were unsuccessful”. Transluce’s report, above, says one agent got around the site’s anti-bot controls. OpenAI’s account says its agents used “third-party browsing and download services” and that the material “appears to have been publicly available”. In OpenAI’s account, individuals’ records were not accessed at any of the 3 sites.

On 2 October the ABC reported another Australian site. The NSW Premier’s Department said an OpenAI model had entered a National Parks and Wildlife Service (NPWS) web application holding historical information and data on fires. The department understands this happened in June, but OpenAI did not tell the government until 1 October. Its investigations so far have found no unauthorised access to personal information. OpenAI says the model gathered “summary fire statistics that weren’t publicly available through the service”, ABC News in the US reported. The NSW Government’s statement said the agent came up with only “public information”, iTnews reported. So the affected government and OpenAI describe the data differently. OpenAI informed the NSW Government and ASD after a 48-hour review of the activity, the Guardian reported.

The Guardian reported on 3 October that the NPWS site was the sixth Australian government website OpenAI had notified since September. We have found only five of them named: the Medicare portal, the AIHW, the NSW crime statistics bureau, the Victorian Department of Health and the NPWS. No source we have found says which site is the sixth. The ABC also reported an attempt on the National Notifiable Disease Surveillance System at the federal Department of Health, but no source we have found says OpenAI notified that department. For more, see our tracker.

The response so far

• A taskforce led by the Department of the Prime Minister and Cabinet. It involves the National Cyber Security Coordinator, the Office of AI, ASD, the Australian AI Safety Institute and Services Australia.
• A referral to Parliament’s Joint Select Committee on Artificial Intelligence.
• An alert from ASD’s Australian Cyber Security Centre on the risks of AI misalignment.
• An invitation from a Senate inquiry into AI and data centres for the chief executives of OpenAI and Anthropic to appear, The Guardian reported. Greens senator Sarah Hanson-Young chairs the inquiry. They were invited for Thursday 1 October, the Sydney Morning Herald reported, with questions on their companies’ growth in Australia and the Medicare incident. The inquiry is run by the Senate Environment and Communications References Committee and reports on 16 November.
• The cancellation of the Senate inquiry’s 1 October hearing in Canberra. The inquiry’s hearings page no longer lists it, and Parliament’s list of hearings for that day showed none. No official reason has been given. The next listed hearing is in Darwin on 3 November. OpenAI and Anthropic had both declined to attend, Quartz reported on 28 September. Citing Reuters and an unnamed source, it said Anthropic had asked for another date because its invitation arrived late. OpenAI said the timeline was too compressed for its executives to travel, the source said. Quartz also reported that OpenAI would “stay in touch should additional hearings be organized”.
• Evidence from OpenAI’s chief strategy officer, Jason Kwon, to the Joint Select Committee on Artificial Intelligence in Sydney on 6 October. He apologised and took several questions on notice, including the technical detail of the Services Australia access (see What OpenAI has said).
• Evidence from Anthropic to the same committee on 6 October, in public and in a closed session. Anthropic’s head of safeguards, Dave Orr, said the company had reviewed “hundreds of millions of transcripts” of its models and found no case of them interacting with Australian government systems in an unauthorised way, the Guardian reported. He also told the committee that Anthropic cannot review most past customer use, because it keeps no copy of those prompts and responses. Notifying the government of a similar incident is currently a matter of Anthropic’s internal policy, he said.
• Plans for new standards on rogue AI incidents, the ABC reported on 29 September. Tech companies would have to report them straight away to the affected organisation and to Australia’s cyber authorities. Ms Gallagher said the Services Australia inbox is now monitored around the clock, the ABC reported. The next day the ABC reported that a rapid review into the OpenAI incident is “due to conclude within weeks”. Its findings are expected to inform the standards, the ABC said.
• A Home Affairs direction, PSPF Direction 002-2026, requiring agencies to take stock of their legacy systems and plan to reduce them by 31 March 2027 (see What the government has said).

Claims that don’t hold up

• That Medicare patient records were hacked. The portal held statistics. The government and OpenAI both said no personal information or patient records are believed to have been accessed.
• That 27 million Australians were affected. The figure came from a journalist’s question about the population, not from any finding.
• That classified information was taken. The Prime Minister described the portal as holding “non-sensitive Medicare information”. OpenAI’s 29 September account says the model retrieved “internal files, credentials and aggregate statistics” and reviewed “technical system information and source code”. Neither the government nor OpenAI has described any of it as classified.
• That OpenAI hacked into every Australian government site it notified. The government says one portal was accessed without authorisation. NSW is still investigating the NPWS fire application, and has found no unauthorised access to personal information. At the AIHW, OpenAI itself says “There was no system compromise”. The ABC reported that the AIHW and ASD found no evidence the AIHW’s systems were compromised. OpenAI’s account of the Victorian and NSW sites describes an exposed access key and configuration data returned by a public tool. Mr Marles said on 24 September the interactions with those sites were “entirely normal”. The NSW bureau says nothing beyond public information was accessed. OpenAI itself says whether the Victorian information should have been accessible “is unclear”.
• That a foreign government was behind it. The Prime Minister said there was “no suggestion of foreign actors”. The agent belonged to OpenAI, a US company, and was running in OpenAI’s own internal testing.

Was this the first case?

Possibly. On our tracker, it is the earliest access to a government system that the affected government has confirmed. Taiwan’s government confirmed an attack that combined hackers with AI agents, and said so in August. But that attack took place in July, after the 18 June access here. Earlier reports from Mexico and from Anthropic (its GTG-1002 case) were not confirmed by the governments involved: Mexico’s agencies said their checks found no breach, and Anthropic named no government. Unlike those cases, no attacker was involved here. See our tracker.

Still unknown

• Whether the government confirms OpenAI’s account that the model could make the server “carry out instructions” through the public reporting interface. Which part of that interface was involved, and whether the guest login played any part.
• The full text of OpenAI’s email.
• Whose credentials the model retrieved, according to OpenAI, what they could unlock, whether it used them, and whether they have been revoked. Neither OpenAI nor Services Australia had said by 29 September, iTnews reported.
• What the non-public files contained, and what files the model wrote. OpenAI’s email describes a test file; its later account and the Prime Minister refer to files written.
• Whether Services Australia and the Victorian Department of Health agree with OpenAI’s account of their systems. The NSW bureau has said nothing beyond public information was accessed.
• Why the NSW Government says the National Parks agent came up with only public information, while OpenAI says the statistics were not publicly available through the service.
• Which OpenAI model was involved. OpenAI calls it experimental and internal-only.
• What the agents did during their attempts on the AIHW website, and whether those attempts are linked to the portal incident.
• Which site is the sixth Australian government website OpenAI notified, according to the Guardian.
• Whether OpenAI finds other Australian incidents. Mr Kwon said on 6 October that the incidents reported so far are the only ones it has found.
• When the Senate inquiry will hear from OpenAI or Anthropic.
• What the rapid review finds.
• What the government taskforce finds, and what OpenAI’s own Australian taskforce recommends.
