The Australian guidelines follow the September 1 release the Australian Government’s Age Assurance Technology Trial results. The trial found that age estimation is feasible and already used by social media, retail, and age-restricted content providers. None of these was considered satisfactory on its own for reliable age assurance, but could be used with other methods. Guided by these findings, the Australian regulatory guidelines do not mandate any method for age assurance. A strong contrast to the prescriptive and intrusive approach to age verification used in the United Kingdom.
