Australian Medicare statistics portal: AI agent bypassed access controls to reach non-public files

Prime Minister Anthony Albanese said an AI agent running an internal OpenAI research task bypassed access controls on an Australian government Medicare statistics portal in June and reached files that were not public. The portal publishes aggregate figures such as spending and is separate from systems handling Medicare claims and personal records. No personal data was said to be involved.
