X, the company formerly known as Twitter, has become the first online platform to be issued with a $610,500 fine under Australia’s Online Safety Act for its failure to meet basic online safety expectations.

X has 28 days to either pay the fine, issued by the e-safety commissioner, Julie Inman Grant, or provide responses to questions X ignored from the commissioner on its work to crack down on child sexual abuse material on the platform.

The legal notices were issued to X, Google, TikTok, Twitch and Discord in February following the first round of notices sent to Apple, Meta, Microsoft, Snap and Omegle last year.
