Victoria s coronavirus lockdown is unnecessary because there are no mystery cases and could have been avoided if the state government had set up a universal QR code check-in system, a diseases expert has told Daily Mail Australia.
Seven million Victorians are being ordered to stay at home in a circuit-breaker lockdown that started on Friday morning as an outbreak in Melbourne grew to 30 cases of the Indian variant of the disease.
But Professor Peter Collignon, of the Australian National University, said short lockdowns impose huge costs and do not help stop the spread of the virus as long as cases and contacts are isolated by a good tracing system.
