Locking down South Australia

We've seen coronavirus lockdowns before, but this one is different. For six days, the entire state of South Australia is under tight restrictions to buy authorities time to trace and contain a COVID-19 cluster that's spreading across Adelaide's suburbs. They're the toughest statewide measures we've ever had in Australia, and if the lockdown all goes to plan it could be the shortest too. So can the state pull this off? Or will the virus spread out of control and kill Christmas? Featured: Adrian Esterman, Professor of Biostatistics and Epidemiology, University of South Australia
