A social media ban for children under 16 passed the Australian Senate Thursday and will soon become a world-first law.

The law will make platforms including TikTok, Facebook, Snapchat, Reddit, X and Instagram liable for fines of up to 50 million Australian dollars ($33 million) for systemic failures to prevent children younger than 16 from holding accounts.

The Senate passed the bill 34 votes to 19, and the House of Representatives overwhelmingly approved it by 102 votes to 13 on Wednesday.

The House has yet to endorse opposition amendments made in the Senate. But that is a formality since the government has already agreed they will pass.

The platforms will have one year to determine how to implement the ban before penalties are enforced.

Meta Platforms, which owns Facebook and Instagram, said the legislation had been “rushed.”

Digital Industry Group Inc., an advocate for the platforms in Australia, said questions remain about the law’s impact on children, its technical foundations and scope.

“The social media ban legislation has been released and passed within a week and, as a result, no one can confidently explain how it will work in practice – the community and platforms are in the dark about what exactly is required of them,” DIGI managing director Sunita Bose said in a statement.

The amendments bolster privacy protections. Platforms would not be allowed to compel users to provide government-issued identity documents including passports or driver’s licenses, nor could they demand digital identification through a government system.

The House is scheduled to pass the amendments on Friday. Critics of the legislation fear that banning young children from social media will impact the privacy of users who must establish they are older than 16.

While the major parties support the ban, many child welfare and mental health advocates are concerned about unintended consequences.
