An attack at a Western Sydney church last week was inextricably linked to social media. The bishop who was stabbed is a social media celebrity, the attack itself was live-streamed, and both the attack and the reaction may have been inflamed by online extremism.

Today, counter-terrorism expert and Lowy Institute fellow Lydia Khalill, on the attack, whether it was an act of terrorism and how we can do more to prevent extremism.

In recent weeks, we’ve covered an appearance by neo-Nazis at a rally in Melbourne, as well as ASIO’s decision to steer away from labels like ‘right’ and ‘left’ when talking about radicalisation here in Australia. The issue of far-right extremism has often been covered in Australia as a political issue, but what about as an issue of safety and security?

Today, we revisit our conversation with the author of ‘Rise of the Extreme Right’, Lydia Khalil, on the far right in Australia, its connections around the world and the best way to stop it from growing.

Australia’s domestic security agency, ASIO, says right-wing extremism now makes up half of its priority cases. So just how big a risk is this movement today? And how did we allow this discredited and dangerous ideology to get a foothold once again?

Today, author Lydia Khalil on how counter-terrorism turned a blind eye to the far right and how we all need to solve that problem.

Australia’s security agencies have introduced new terminology to talk about the threats we face but they are carefully avoiding the term "right-wing". Today, Lydia Khalil on what’s behind this change and why the language we use to describe a threat matters.
