Australia’s aging IT infrastructure leaves government data vulnerable to rogue AI agents

Former chief UN cyber negotiator Johanna Weaver warned that Australia’s reliance on decades-old computer systems makes government and economic data susceptible to exploitation by autonomous AI agents. She highlighted a recent incident where an OpenAI-controlled agent accessed the Medicare statistics portal and three additional Services Australia sites through such legacy infrastructure. In response, the federal cabinet will convene to assess the fallout, while a cross-government rapid review involving the prime minister’s department, the national cybersecurity coordinator and the Australian AI Safety Institute is under way.

OpenAI has paused training of its newest models and said it will only resume once stronger safeguards are in place. Weaver called for a “digital spring clean” to retire outdated systems, move sensitive data elsewhere, and for AI firms to be barred from releasing models they cannot control, with accountability for any harm caused. Lawmakers, including shadow defence minister James Paterson and Greens senator Sarah Hanson-Young, are pressing AI executives for testimony in a parliamentary inquiry.
