with digital platforms. Under the new rules, major platforms — including Facebook, Instagram, TikTok, Snapchat, X, YouTube, Reddit, Twitch, Kick, and Threads — will be required to deactivate all existing accounts held by under-16s and block new sign-ups until users reach the age threshold. Companies that fail to comply could face penalties of up to $49.5 million . The enforcement is being overseen by Australia’s eSafety Commissioner , who will determine whether platforms have taken “reasonable steps” to identify and remove underage accounts. If children migrate to other lesser-known apps, those platforms may also be added to the list in the coming months. How Age Verification Will Work Each platform will use its own methods to confirm a user’s age. Snapchat plans to rely on behavioral signals and listed birth dates. TikTok says it will use a “multi-layered” age-assurance system based on various signals. YouTube will assess age through Google account data and additional indicators. Meta (Facebook/Instagram) has not disclosed its full method, emphasizing that ID checks cannot be the only tool. Teens affected by the ban will be able to download their data or freeze their accounts until they turn 16, depending on the platform. What Apps Are Not Affected Platforms considered lower-risk such as Roblox, YouTube Kids, Pinterest, Google Classroom, WhatsApp, Discord, LinkedIn, and Steam are not included in the ban. Authorities stated that educational tools, gaming platforms, and communication apps designed with parental oversight do not fall under the new restrictions. Could the Ban Be Delayed? Although a legal challenge has been launched and a parliamentary report recommended postponement, the Australian government insists the rollout will proceed as scheduled. Technology giants including Meta, TikTok, YouTube, Snapchat, Twitch, and Kick have confirmed they will comply. Officials have warned that the transition may not be flawless on day one, and some under-16 accounts may take time to fully disappear as systems update nationwide. A Global Turning Point for Online Safety Australia’s move is being closely watched by governments around the world. With online risks including grooming, graphic content exposure, and addictive algorithms increasingly under scrutiny, the under-16 ban is seen as a pioneering model for future digital policy. Advocates argue that this bold step could redefine childhood in the digital age, giving younger generations a safer, healthier relationship with the online world.
