Sydney Harbour Bridge lights up in Australia's national colours to mark the under 16s social media ban. Australia has ordered 10 major platforms including TikTok, Alphabet's YouTube and Meta's Instagram and Facebook to block around one million users under the age of 16 or face massive fines. Some 200,000 accounts have already been deactivated on TikTok alone, the government said, with "hundreds of thousands" to be blocked in the coming days. #SydneyHarbourBridge #Australia #SocialMedia #TikTok #
