“Social media is doing harm to our kids and I’m calling time on it,” Prime Minister Anthony Albanese said.

The legislation will be introduced in Parliament during its final two weeks in session this year, which begin on Nov. 18. The age limit would take effect 12 months after the law is passed, Albanese told reporters.

The platforms including X, TikTok, Instagram and Facebook would need to use that year to work out how to exclude Australian children younger than 16.

“I’ve spoken to thousands of parents, grandparents, aunties and uncles. They, like me, are worried sick about the safety of our kids online,” Albanese said.

The proposal comes as governments around the world are wrestling with how to supervise young people's use of technologies like smartphones and social media.

Social media platforms would be penalized for breaching the age limit, but under-age children and their parents would not.

“The onus will be on social media platforms to demonstrate they are taking reasonable steps to prevent access. The onus won’t be on parents or young people,” Albanese said.

Antigone Davis, head of safety at Meta, which owns Facebook and Instagram, said the company would respect any age limitations the government wants to introduce.
