MELBOURNE: Australian Prime Minister Anthony Albanese welcomed a world-first social media ban for children younger than 16 that took effect Wednesday as families began taking back power from tech giants but warned the implementation would be difficult.

Many children posted farewell messages, while parents reported distraught children discovering they’d been shut out of platforms as the landmark law took effect. Some young children reported fooling the platforms’ age estimation technology by drawing on facial hair. Parents and older siblings are also expected to help some children circumvent the restrictions.

“This is the day when Australian families are taking back power from these big tech companies and they’re asserting the right of kids to be kids and for parents to have greater peace of mind,” Albanese told the Australian Broadcasting Corp.

“This reform will change lives. For Australian kids ... allowing them to just have their childhood. For Australian parents, enabling them to have greater peace of mind. But also for the global community, who are looking at Australia and saying: well, if Australia can do it, why can’t we?” Albanese later told a gathering of reform supporters at his official Sydney residence, including parents who blame social media for a child’s suicide.
