On the topic of Victoria – and the government's controversial decisions to reintroduce a curfew and close playgrounds – Professor Blakely says the state has two weeks before the tough measures can no longer be justified.
"The playgrounds are acting as a place of transmission," he said, describing scenes in Melbourne last weekend, where there were "all the parents pushing kids on the swing with their masks off drinking their lattes".
"So we have a choice. We either leave them open and reduce our chance of eliminating again or we close them and do what I call the big swing heave ho for the next few weeks. We go hard and try to eliminate.
"Queensland is opening up to having sporting events. South Australia's got no cases at the moment. If we give it one big heave ho for two weeks, we might have a nice time between October and November. I think it is worth it.
"If we haven't eliminated after two weeks I don't think keeping the playgrounds closed will be a good option to be honest."
Prof Blakely added that if he were chief healh officer Brett Sutton, "I don't think I could keep imposing severe restrictions beyond two weeks of now".
