Online Safety Amendment (Social Media Minimum Age) Act 2024

Australia's under-16 social-media minimum-age law took effect on December 10, 2025, requiring age-restricted platforms to take reasonable steps to prevent Australians under 16 from creating or keeping accounts, with penalties up to 49.5 million Australian dollars for systemic non-compliance. In its 2025 assessment, eSafety designated the age-restricted platforms and added Reddit, alongside Facebook, Instagram, Snapchat, Threads, TikTok, Twitch, X, and YouTube. Reddit added age restrictions before the law commenced and uses third-party age verification. eSafety subsequently sent compulsory information notices to the platforms asking how many under-16 accounts had been deactivated. The law marks one of the first national mandates forcing Reddit to exclude minors entirely.
