Australia is set to become the first country to enforce a minimum age for social media use starting Wednesday, requiring platforms such as Instagram, TikTok, and YouTube to block over a million accounts. The move marks the start of what many expect will be a global wave of regulation.
From midnight (1300 GMT), ten major platforms must prevent Australians under 16 from accessing their services or face fines of up to A$49.5 million ($33 million). While the law has drawn criticism from major tech companies and free speech advocates, it has been welcomed by parents and child welfare groups. The rollout ends months of debate over whether governments can restrict children from using technology that is deeply integrated into daily life and launches a live experiment being watched globally by policymakers frustrated with the tech industry’s slow adoption of harm-reduction measures.
Countries from Denmark to Malaysia—and some U.S. states, where platforms are scaling back safety features—are considering similar measures, following revelations that Meta knew its products contributed to body image and mental health issues among teenagers but publicly denied the link. “While Australia is the first to adopt such restrictions, it is unlikely to be the last,” said Tama Leaver, a professor of internet studies at Curtin University. “Governments worldwide are observing how Big Tech’s power was successfully challenged. Australia’s social media ban is very much a canary in the coal mine.”
A UK government spokesperson, referencing its July rules requiring websites hosting pornography to block users under 18, said it was “closely monitoring Australia’s approach to age restrictions” and emphasized, “When it comes to children’s safety, nothing is off the table.”
Australians themselves will scrutinize the impact closely. The eSafety Commissioner, tasked with enforcing the ban, has partnered with Stanford University and 11 academics to study the effects on thousands of young Australians over at least two years.
Initially, the ban targets ten platforms—including YouTube, Instagram, and TikTok—but the government has said the list will evolve as new apps emerge and young users migrate. All platforms except Elon Musk’s X have committed to compliance through age inference (estimating age from activity) or verification methods like selfies, ID documents, or linked bank accounts. Musk criticized the move as a “backdoor way to control access to the internet by all Australians,” while many platforms argue it infringes on free speech. A High Court challenge is pending.
For social media companies, the ban represents a new era of stagnation, with user growth plateauing and engagement declining. Platforms note that under-16s generate limited ad revenue but argue the ban disrupts the pipeline of future users; 86% of Australians aged 8–15 were on social media just before the law took effect.
“The days of social media as a platform for unbridled self-expression are coming to an end,” said Terry Flew, co-director of the University of Sydney’s Centre for AI, Trust and Governance. While platforms have implemented minimum ages of 13 and additional privacy protections in response to criticism and regulatory pressure, Flew added, “Had these structures been in place during social media’s boom period, this debate might not even exist.”
