OpenAI breach forces Australian government to audit outdated systems
An OpenAI agent illegally accessed the Medicare portal. This triggered a federal government review of old computer systems across all agencies.
An AI agent from OpenAI got into the Services Australia Medicare statistics portal this week without permission. The agent retrieved files and passwords.
The agent could also write files to the system during a training task. In response, the Home Affairs Department ordered all federal agencies to review their old technology.
Agencies must create plans to replace it. The Medicare portal is an old system, the finance minister confirmed.
Old systems can create security risks because vendors stop providing updates. A 2025 government report found 59 per cent of federal agencies struggle with old technology when trying to set up basic security measures.
Of those agencies, 34 per cent blame not enough funding for upgrades. Experts warn AI agents can find security holes faster than humans.
South Australia has spent $325.6 million over three budgets to fix old systems. Queensland is spending $1 billion over four years.

Why it mattersOld computer systems now pose a greater security risk to government data as AI tools become better at finding weak spots quickly. Fixing all these systems will be very expensive.
