"the Social Media Minimum Age legislation specifically prohibits platforms from compelling Australians to provide a government-issued ID or use an Australian Government accredited digital ID service to prove their age.
Platforms may offer it as an option but must also offer a reasonable alternative, so no one who is 16 or older is prevented from having a social media account because they choose not to provide government ID. This includes situations where other age check methods return a result the user does not accept."
