Australia's Social Media Age Ban: Early Insights After 100 Days
Australia enacted a law (effective December 10) banning under-16s from creating accounts on many social platforms as an extension of the Online Safety Act, called the "Social Media Minimum Age." The eSafety regulator commissioned the Stanford Social Media Lab to run a two-to-five year scientific evaluation with a dozen universities, combining a longitudinal survey of 4,000+ children and parents, passive smartphone usage tracking, interviews, and administrative data. After roughly 100 days, Stanford researchers report early patterns: younger children (10–12) generally accept the change, while 14–15-year-olds report anger and a sense of being deplatformed; adherence is imperfect with some youths returning via new accounts. Early observed substitution behaviors include migration toward gaming chats and AI chatbots (e.g., ChatGPT, Grok). The study will track intended and unintended consequences to inform possible law adjustments.
Major national regulation altering youth access to social platforms creates significant changes to audience availability, marketer reach and platform governance; results will inform other jurisdictions and platform compliance, affecting ad monetization and policy approaches globally.

- The legal change is an extension of the Online Safety Act, officially called the "Social Media Minimum Age."
- The Australian eSafety regulator commissioned the Stanford Social Media Lab to evaluate the policy via a multi-year study involving >4,000 children and parents, smartphone tracking, interviews and administrative data.
- Early findings after 100 days: 10–12 year-olds often accept the ban; 14–15 year-olds report anger and feelings of being deplatformed; adherence is not complete with reports of new accounts.
- Platforms explicitly affected include Instagram, Tiktok, Snapchat, Youtube and Twitch; messenger apps, some gaming platforms (Roblox, Lego Play), Discord and YouTube Kids are excluded; platforms that don't require accounts remain accessible.

Australia Investigates Platforms Over Under-16 Ban
Australia introduced a law in December banning children under 16 from using social media. Four months after the law took effect, the Australian regulator eSafety is investigating five major platforms — Facebook, Instagram, TikTok, Snapchat and YouTube — for possible breaches related to enforcing age limits. Communications Minister Anika Wells said the regulator’s first report exposed "unacceptable systems" that allow repeated attempts to bypass age-verification checks. eSafety Commissioner Julie Inman Grant reported that roughly 5 million accounts had been removed, suspended or restricted by early March, but regulators remain concerned many under-16 users remain active. The government says it will pursue strong action if platforms are found to be systematically failing to meet their legal obligations under the new social-media ban.
Study: Australia’s Under-16 Social Media Ban Ineffective
Australia, which introduced a nationwide ban late last year prohibiting children under 16 from using social media, has one of the first studies evaluating the policy’s impact. The newly published study finds the ban has so far had little effect on the actual usage behaviour of under-16s. The research outcome has drawn attention from both supporters and critics of the measure. The article was published by HORIZONT on June 25, 2026 and is authored by Rosa Schmitz and HORIZONT Online.
Countries Moving to Ban Social Media for Children
Multiple countries have announced or proposed laws to restrict social media access for children and teens, aiming to reduce harms such as cyberbullying, addiction and exposure to predators. Australia was first, enacting a ban for under-16s in December 2025 and requiring platforms to use age-verification methods or face fines. The U.K. government, announced by Prime Minister Keir Starmer on June 15, 2026, said it will ban social media for under-16s and exclude some messaging apps; limits on certain AI chatbots were also proposed. Other governments either have passed, drafted or proposed similar measures with varying minimum ages (commonly 14–16) — including Austria, Canada, Denmark, France, Germany (proposal), Greece, Indonesia, Malaysia, Poland, Slovenia, Spain and Turkey. Critics warn about privacy, enforceability and effectiveness of age checks.
