World-first law forces major platforms to block or delete accounts of users under 16 as regulators begin enforcement
As of December 10 2025, Australia has commenced enforcement of its landmark social media law requiring users under 16 to lose access to major platforms — a move that has instantly impacted millions of children and teenagers across the country.
Platforms including
Facebook, Instagram, TikTok, YouTube, Snapchat, X (formerly Twitter), Reddit, Twitch, Threads, and Kick must now suspend under-16 accounts and block new registrations.
Companies that fail to comply are facing fines up to A$49.5 million.
The law — passed in November 2024 as the — represents the world’s first nationwide social media age-restriction policy of this breadth.
Regulators and government authorities say the legislation aims to protect youth from online harms, including content exposure, cyberbullying and addictive algorithms.
Tech firms have moved swiftly.
began deactivating hundreds of thousands of under-16 user accounts on December 4, ahead of the legal deadline, notifying affected teens and offering ways to download their data.
Other platforms followed suit, and most affected users are now locked out — though authorities acknowledge that verifying age with full accuracy will remain a challenge.
The roll-out has already triggered strong reactions.
Some parents and youth-safety advocates welcome the change as a necessary step to safeguard children’s mental health and reduce online risk.
Others — including affected teenagers — warn the ban may sever social connections, isolate youth, and drive them toward unregulated or harder-to-monitor digital spaces.
Simultaneously, a formal legal challenge has been launched in the High Court of Australia by a youth-rights coalition arguing that the ban infringes on the implied constitutional freedom of political communication.
The plaintiff group contends that the law disproportionately restricts political and social expression for a generation of young Australians.
As the world watches, the unfolding outcome of the ban will serve as a test case for digital-policy debates globally — illuminating whether governments can effectively regulate social media for minors without eroding rights or driving users into less safe online corners.
