The ATO refused a FOI request for the Android package file (.apk) of its myID application, citing section 47E(d) of the FOI Act. The refusal decision states that releasing the file would create an unauthorised distribution channel outside the Google Play Store, compromising existing security safeguards designed to ensure users download verified, up-to-date versions and prevent unauthorised modification or tampering. The ATO determined that such a release could reasonably be expected to substantially adversely affect agency operations by increasing risks of misuse, compromised versions, and undermining public confidence in the security of ATO and broader Commonwealth IT systems, particularly concerning the Australian Government Digital Identity System. The decision reflects the ATO's assessment that operational security interests outweigh transparency considerations in this instance.
