Parliament officially passed the bill on Friday, making it the first ban of its kind in the world, according to the Associated Press. The law prohibits social media companies from offering online accounts to anyone under the age of 16. Its official passage on Friday came after the Senate voted 34-19 to approve it on Thursday and the House of Representatives overwhelmingly approved it in a 102-13 vote, on Wednesday. On Friday, the House endorsed opposition amendments made in the Senate—the final stamp of approval to make the bill law.

Social media companies now have about a year to set protocols for barring users under 16 from having accounts. Companies that don’t comply with the law could face a fine of up to $33 million. The law applies to platforms including TikTok, Facebook, Snapchat, Reddit, X, and Instagram.

What are proponents of the law saying? Australian Prime Minister Anthony Albanese celebrated the bill’s passage on X, saying that Australia’s government is doing everything it can to keep the nation’s kids safe. The law is about supporting parents and making sure media companies take their social responsibility seriously, Albanese previously wrote on Tuesday. Young Australians are not mentally developed enough to ignore online hate or to spot fake content, he said. The world has seen disturbing mental health impacts in children after the rise of social media, Sen. Sarah Henderson argued before the Thursday vote. A government poll released Tuesday found that more than 75% of Australians supported the age limit.

What arguments did critics of the law make? Sen. Sarah Hanson-Young slammed the bill before the Thursday vote, claiming it had no substance and only offered the appearance of safety. She characterized the bill as embarrassing, saying it was merely an example of baby boomers trying to tell young people how the internet should function. This law won’t help people already addicted to social media algorithms or people who struggle to make social connections because of that addiction, she said. Sen. David Shoebridge also argued against the law’s passage, saying that minors who identify as LGBTQ need social media to be connected with others like themselves.
