We are also not alone in making these changes. Since 2012, 15 other countries have adopted a self-identification process, as well as the Australian states of Tasmania and Victoria. There has been no substantial evidence found on any serious or unmanageable consequences of introducing a self-identification process. However, if any unintended consequences do arise, we have built in a statutory review of the self-identification provisions five years after the commencement of this bill, as per the 2018 select committee's recommendations.
