In this podcast, Madeleine Nyst talks to Michael Shoebridge about the strategic implications of the PNG–Australia–US joint naval base on Manus Island and the message that sends to China. In the wake of the Bourke Street attack, we talk to Dr Emily Corner of the Australian National University about the misinformation that surrounds discussion of terrorism, radicalisation and mental health, and Jacqueline Westermann speaks with Dr Isaac Kfir about the latest developments in the Brexit process.
