Meta has deactivated more than half a million social media accounts belonging to children in compliance with Australia's new social media law.

The law came into effect on December 10 and bans social media accounts for children under the age of 16. It requires big platforms including Meta, TikTok and YouTube to stop holding accounts for those under that age.

More than half a million accounts deactivated

Meta said that between December 4 and 11 it had deactivated 544,052 accounts it believed were held by users aged under 16. This included 330,639 accounts on Instagram, 173,497 on Facebook and 39,916 on Threads.

Companies found not to be in compliance face fines of up to  $49.5 million Australian  (€28.4 million, US$33 million).

In a statement, Meta said it was committed to complying with the law but said "our concerns about determining age online without an industry standard remain."

"We call on the Australian government to engage with industry constructively to find a better way forward, such as incentivizing all of industry to raise the standard in providing safe, privacy-preserving, age appropriate experiences online, instead of blanket bans," Meta said.

Meta calls for better age verification measures

The tech giant went on to renew a call for app stores to be required to verify ages and also get parental approval before  apps can be downloaded.

"This is the only way to guarantee consistent, industry-wide protections for young people, no matter which apps they use, and to avoid the whack-a-mole effect of catching up with new apps that teens will migrate to in order to circumvent the social media ban law," the company said.

Australian public broadcaster ABC reported that government was expected to release data showing how many under-age Australians had been booted off platforms impacted by the ban this week.

Australia's ban has been lauded by advocates worldwide, and has prompted other countries to consider similar measures, including Germany.
