•The Australian Senate has ordered the OAIC to release full details of the Amex investigation.
•The OAIC's previous report was abridged due to concerns over individual harm and cybersecurity risks.
•Amex must implement stronger access controls within six months following identified insider breaches.

The Australian Senate has mandated the Office of the Australian Information Commissioner (OAIC) to disclose the complete findings of its investigation into American Express (Amex) regarding security weaknesses. The investigation revealed significant access control issues following two insider breaches. The OAIC had previously only published an abridged report citing potential harm to individuals and cybersecurity risks as reasons for withholding full details. The Senate's motion, passed with a vote of 33-21, requires the OAIC to provide the full determination and related correspondence by July 28, 2026. This move aims to enhance transparency and accountability regarding the handling of privacy breaches by Amex. The OAIC had ordered Amex to implement stronger access controls within six months after the breaches were identified.
