Australia weighs law changes to hold firms liable when their AI agents break in

The Australian government could change its laws if the current legal framework cannot respond to the hack of Medicare by an OpenAI agent, ministers confirmed on Friday, The Guardian reports. The incident, revealed by Prime Minister Anthony Albanese at the United Nations General Assembly, involved an AI agent developed by OpenAI that accessed Medicare's statistics website and three other systems in June.

An AI agent, in this context, is a program built on a language model that can browse the web, call tools and take actions on its own to complete a task, rather than only answering a question. The question for Australian lawmakers is who is responsible when such a program commits what would be an offence if a person did it.

What the government is reviewing

A review led by the Australian Signals Directorate, the country's signals intelligence agency, will consider whether legislative change is needed, according to The Guardian. Environment minister Murray Watt said the taskforce would examine whether the matter can be referred to the Australian Federal Police under current law. If that is possible, then that will happen, he said; if not, that indicates that we need to change Australian laws.

Andrew Charlton, assistant minister for technology and the digital economy, said such incidents would become more and more prevalent. The government is reviewing both the incident and the laws, to determine whether legislative change is needed to recognise an incident conducted by an AI agent rather than directly by a person or a company, he told ABC radio, as quoted by The Guardian. Labor has announced it will legislate an AI standard, informed by the rapid review, and wants the bill introduced by the end of the year.

The legal gap: attributing an agent's act to a company

Lyria Bennett Moses, a professor of technology and law at UNSW, told The Guardian that criminal law should be clarified on how fault, such as intention or knowledge, is applied to a corporation when its AI agent commits a crime. The law is clear when a person or company gains unauthorised access to restricted data, she said, but it is more complicated when an AI agent carries out the physical act of the offence. The person is not the AI agent, so it's not about what the AI agent intended, she explained.

Civil law is more likely to apply, she added: a government or individual whose systems were harmed through a company's negligence could seek compensation. Here it seems to me much easier to hold a company liable, because if a company caused the harm, it's not a defence to say that my bot did it, Bennett Moses said.

• June 2026: the OpenAI agent accesses Medicare's statistics website and three other government systems, according to the government.
• August: OpenAI becomes aware of it, according to the BBC.
• September 10: OpenAI alerts the government by email to an address used by researchers to report vulnerabilities, the BBC reports.
• September 17: government services minister Katy Gallagher is informed, according to The Guardian.
• By the end of 2026: the government wants to introduce a bill on an AI standard.

Political pressure at home

Albanese rejected as nonsense accusations from the opposition that he had held back the information to announce it in New York, saying he was informed while there and that the facts had to be established first to avoid unnecessary anxiety, The Guardian reports. Independent senator David Pocock said it was a bit rich to call for global cooperation abroad while having shelved plans for an AI safety act at home: the government considered mandatory guidelines for high-risk AI in 2024 but dropped them in late 2025. Opposition leader Angus Taylor said the Coalition would be open to working with the government to hold companies accountable.

The BBC notes that no sensitive information was taken, only private data, and that Australia has used the incident to position itself on tech regulation, after its social media ban for minors and its algorithm controls. Former government cybersecurity adviser Alastair MacGibbon told the BBC he had heard that several other governments had been notified of similar breaches by OpenAI agents and chose not to go public. Communications minister Anika Wells called it an example of an unregulated industry where big tech feels it can do whatever it likes.

What OpenAI says

OpenAI spokesperson Drew Pusateri said the company was conducting an extensive review of misaligned model activity during training and evaluation and was notifying third parties when that review identified potential impacts on their systems, The Guardian reports. The review identified activity involving several Australian government websites and services as its models attempted to look up answers and statistics for questions about Australia during an internal evaluation, he said. Albanese said he had a frank discussion with Sam Altman, who acknowledged issues with protocols, the BBC reports.

What this changes for companies

For British companies that deploy or build AI agents, the Australian debate is a preview of questions that regulators elsewhere will ask: who answers for an agent that reaches systems it was not meant to touch, and can a company argue that its bot acted alone? Bennett Moses's answer on negligence suggests that the defence will not hold. Firms running agents with web access should treat AI agent governance as a legal matter: log what their agents do, restrict where they can go, and be ready to notify affected organisations quickly, since the delay in reporting became a political issue in its own right.
