Research from June 2026 suggested up to 80% of under-16s were still accessing platforms. :INFO What is not known yet • Whether the High Court will rule the ban unconstitutional, uphold it, or find it valid with possible legislative tweaks. • How long the Full Court will take to hand down its decision; no date has been given. • Whether Reddit's secondary argument -- that it falls outside the statutory definition -- will be decided on the same timeline or separately. • Whether the eSafety Commissioner will issue fines to Meta, TikTok, Snap or YouTube while the case is pending. :CHECKLIST [links:https://www.abc.net.au/news/2026-11-03/high-court-challenge-to-under-16s-social-media-ban/107336886] What happens next [x] Two days of oral argument (3-4 Nov 2026) [ ] High Court reserves decision (date not set) [ ] eSafety Commissioner compliance investigations conclude for Meta, TikTok, Snap, YouTube [ ] If ban upheld: enforcement and potential first fines [ ] If ban struck down: government must decide whether to amend or drop the law :LINK https://www.abc.net.au/news/2026-11-03/high-court-challenge-to-under-16s-social-media-ban/107336886 ABC News -- High Court challenge overview :LINK https://www.capitalbrief.com/article/reddit-argues-uncertain-science-cant-justify-social-media-ban-a131b18b-6362-40a6-9e88-f945736d6c5e/ Capital Brief -- Reddit's constitutional arguments :LINK https://en.wikipedia.org/wiki/The_Digital_Freedom_Project_Incorporated_v._Commonwealth Wikipedia -- case summary and documents :LINK https://gulfnews.com/world/oceania/internet-rights-group-challenges-australia-under-16-social-media-ban-3-1.500360384 Gulf News -- international coverage
