MELBOURNE — Australia’s communications minister introduced a world-first law into Parliament on Thursday that would ban children under 16 from social media, saying online safety was one of parents’ toughest challenges. Michelle Rowland said TikTok, Facebook, Snapchat, Reddit, X and Instagram were among the platforms that would face fines of up to 50 million Australian dollars ($33 million) for systemic failures to prevent young children from holding accounts. “This bill seeks to set a new normative value in society that accessing social media is not the defining feature of growing up in Australia,” Rowland told Parliament.

X owner Elon Musk warned that Australia intended to go further, posting on his platform: “Seems like a backdoor way to control access to the Internet by all Australians.” The bill has wide political support.
