Australia’s parliament has passed a world-first law banning social media for children under 16, putting tech companies on notice to tighten security before a cut-off date that’s yet to be set. The Senate approved the social media ban late on Thursday,

In Sydney, reaction to the ban was mixed. Children, meanwhile, said they would try to find a way around the ban.

Online safety campaigner Sonya Ryan, whose 15-year-old daughter Carly was murdered by a 50-year-old pedophile who pretended to be a teenager online, described the Senate vote as a “monumental moment in protecting our children from horrendous harms online.”
