The Department of Home Affairs released internal guidance documents on the use of Signal, an encrypted messaging application approved for corporate iOS devices since 7 April 2020 as a replacement for WhatsApp. The guidance covers three main areas: creating private group chats (with no size limits and automatic end-to-end encryption), and initiating voice and video calls with end-to-end encryption. Critical to the policy is a mandatory requirement that all official decisions made via Signal must be documented and saved to the department's TRIM records management system, and chat backup functionality is explicitly prohibited within the Signal application.
