Reddit takes on Australia's social media ban for under-16s in top court

Australian government lawyers have argued in favour of the country's under-16 social media ban before the country's highest court, in a case brought by Reddit and a digital rights group.

Reddit and the Sydney-based Digital Freedom Project argue that the law goes too far and breaches the freedom of political communication implied in Australia's constitution. Reddit also says it should not be on the list of 10 platforms covered by the ban, describing the law as poorly targeted.

Government lawyers told the court that social media exposes children to risks including anxiety, depression and suicidal thoughts, and that the limits on political expression are small and indirect.

The ban, which covers platforms including Facebook, Instagram, YouTube and Reddit, came into force in December 2025. Companies that fail to take reasonable steps to remove underage users face fines of up to A$49.5 million. About five million accounts have been closed so far, though officials admit many teenagers still get around the age checks.

The court has adjourned after two days of hearings and is expected to give its decision in the coming months.
