Australia’s world-first ban on social media for children under 16 faced its most critical legal test yet on Tuesday, as the High Court opened hearings on a constitutional challenge brought by Reddit.
The landmark legislation, which took effect on December 10, 2025, forces major platforms including Facebook, Instagram, TikTok, YouTube, and Reddit to block users under 16 from holding accounts. Nearly 5 million accounts have been purged or blocked since the rules went live. But the policy is now colliding directly with core questions of free expression and constitutional rights.
During Tuesday’s opening arguments in Canberra, lawyers for Reddit slammed the restrictions as poorly designed and ineffective. They argued that the federal law imposes sweeping burdens on political communication, infringing upon an implied freedom recognized by the High Court under Australia’s Constitution.
The Core Legal Battle
Reddit’s legal team emphasized that while teenagers are barred from posting, commenting, or participating in digital discussions without verified accounts, the law fails to achieve its stated safety goals. The company also contested its classification as an age-restricted platform under the statute.
Advocacy groups joining the challenge argue that a blanket ban is a blunt instrument. They point to mounting evidence that young users frequently bypass restrictions using virtual private networks and fake ages, potentially driving them toward less regulated and riskier corners of the internet. Research released earlier this year suggested that up to 80 percent of minors continued using social platforms despite the rules.
Government Defense and Public Backing
The federal government has defended the legislation as an essential shield against online harms and addictive platform features. Ministers maintain that the law provides much-needed relief to parents struggling to manage children’s screen time, and have pushed back against claims that the restrictions violate fundamental rights.
The policy has drawn fierce political debate nationwide. South Australia announced it would actively join the federal government’s defense in the High Court, underscoring the deep divisions between state leaders and tech firms over digital governance.
The High Court hearings are scheduled to conclude on Wednesday, with a ruling expected in the coming months. Whatever the outcome, the case marks a pivotal moment for global regulation, testing how far democratic governments can go to police youth access to the digital public square.
