Platform hosts would also have to notify Australia if they discover their service is streaming violent content taking place within the country. If they don't, they could face fines up to $168,000 AUD for an individual and $840,000 AUD for a company. The new legislation would ultimately be similar to those requiring companies to notify law enforcement if someone is using their service to access child porn.

Prime Minister Scott Morrison wasn't shy about the motivations: he argued that social media sites have a "responsibility to take every possible action" to ensure they aren't serving as vehicles for terrorist agendas. He hoped that Australia would serve as a "model approach" for G20 countries to follow.

The measure wouldn't prevent news outlets from reporting on events, according to Communications Minister Mitch Fifield.

If the bill becomes law, it would pressure Facebook, Twitter and other sites to do whatever they can to pull videos of violent crime. However, there are questions about the viability of the law. Facebook and YouTube struggled to remove every instance of the Christchurch shooter's video even with heavy automation at work, and it didn't take much for people to edit these videos in a way that would thwart AI filters. It's not clear if the proposed law would consider those reasonable efforts. They might be off the hook, but they could also face stiff penalties simply for missing a single copy of a video.
