Australia will ban children under 16 from using social media, after its parliament approved the world's strictest laws. Tech companies could be fined up to A$50m ($32.5m; £25.7m) if they don't comply. But as many parents know, keeping teenagers off social media is a challenge. So, can a ban like this really work? And how might it be implemented?

In this episode, Lucy Hockings speaks to the BBC's cyber correspondent Joe Tidy and our correspondent in Australia, Katy Watson.
