Google and Facebook-owner Meta Platforms urged the Australian government on Tuesday to delay a bill that will ban most forms of social media for children under 16, saying more time was needed to assess its potential impact.

Global tech giants including Meta, TikTok and Google have heavily criticized Australian legislation to ban children under 16 from accessing social media platforms, setting the stage for a policy fight as the government tries to push the bill through parliament this week.

An advocate for major social media platforms has told Australia’s Parliament that a plan to ban children younger than 16 from the sites should be delayed rather than being rushed to approval this week
