COVIDSafe[14][15] was a digital contact tracing app released by the Australian Government on 26 April 2020[16][17] to help combat the ongoing COVID-19 pandemic.[18] The app was intended to augment traditional contact tracing by automatically tracking encounters between users and later allowing a state or territory health authority to warn a user they have come within 1.5 metres (4 ft 11 in) with an infected person for 15 minutes or more.[19] To achieve this, it used the BlueTrace and Herald protocol, originally developed by the Singaporean Government and VMWare respectively,[20][21] to passively collect an anonymised registry of near contacts.[22] The efficacy of the app was questioned over its lifetime, ultimately identifying just 2 confirmed cases by the time it was decommissioned on 16 August 2022.[23]
