The Australian government has announced that YouTube will be included in new legislation that bans children under the age of 16 from using social media.

The Australian government announced YouTube will be among the social media platforms that must ensure account holders are at least 16-years-old from December, reversing a position taken months ago on the popular video-sharing service.

Australia said on Wednesday it will add YouTube to sites covered by its world-first ban on social media for teenagers, reversing an earlier decision to exempt the Alphabet-owned video-sharing site and potentially setting up a legal challenge.
