Young Australians are being moved to violent extremism in a matter of days as the speed and scale of radicalisation accelerate.
For years, terrorists and extremists have used the internet to target young people and convince them to plan and carry out violent acts.
But the recent use of social media, gaming platforms, online forums, the dark web and private group chats has allowed bad actors to more quickly and effectively radicalise people, the Australian Federal Police warns.
"Where it used to take months or years to radicalise a person, in some cases, it's happening in days," AFP Commissioner Krissy Barrett told senate estimates on Thursday.
"We see the speed and scale of radicalisation becoming one of our most significant challenges, especially when it comes to young people."
