'Sydney HEMS' is the Pre-Hospital and Retrieval Team for the New South Wales Ambulance Service. Members of the team: Cliff Reid, Karel Habig and Geoff Healy have got together to produce some great introductory podcasts. Although aimed at those starting in PHEM, I found listening to three well respected experts discussing some of the basics in their speciality a really valuable experience.
