The Institute, in association with the Australian Healthcare and Hospitals Association (AHHA), have lent their support to the Australian Government’s contact tracing app to aid national efforts to manage and suppress COVID-19. However, we are urging the Government to “do no harm” in implementing the technology. AIDH and AHHA have developed 10 principles for the Australian Government to use in its enabling legislation. The inclusion of the recommended principles will increase the likelihood of more widespread adoption of the app, which is desirable for rapid contact tracing. The principles cover communication and design, data collection “scope creep”, data security, opt-in and end dates, anonymity, usage rights, legal protection and evaluation.
