Australia's pioneering social media ban is casting ripples around the world.  

The new law sets a mandatory age limit of 16 or older for accounts on platforms like Facebook, TikTok, and YouTube.

Now countries like Malaysia and Denmark are following the Australian lead with similar approaches. 

AUT communications studies professor Patrick Usmar told Andrew Dickens enforcement will be difficult, but it should limit exposure to the thousands of ads kids had been seeing every week.  

He says parents now won't need to persuade their kids to get off it, and teachers won't need to monitor it as much, because they can just say it's the law now.
