Reddit has initiated a legal challenge against Australia's new law banning social media usage for users under 16, enacted on December 10, 2025. The law imposes fines of AUS$49.5 million (US$33 million) for non-compliance. Reddit argues the law is invalid for its platform, emphasizing its nature as a discussion forum rather than an age-restricted app. The Australian government asserts that the ban prioritizes child safety, stating, "We will stand firm to protect young Australians."
