It is an ambitious social experiment of our moment in history — one that experts say could accomplish something that parents, schools and other governments have attempted with varying degrees of success: keeping kids off social media until they turn 16.

The law would fine social media platforms like TikTok, Facebook, X, and Instagram for failing to stop children younger than 16 years old from having accounts.

Australia’s parliament has passed a law banning social media for children under 16, putting tech companies on notice to tighten security before a cut-off date that’s yet to be set.
