During the whole coronavirus period it has seemed to me that Australia has a world class expert on the topic behind every tree. One who stood out to me was Professor Raina MacIntyre, Head of the Biosecurity Program at the Kirby Institute and NHMRC Principal Research Fellow, UNSW. She seemed to tell it like it is, had an appropriate sense of the precautionary principle, and was not on any panel advising politicians. It is well-known that experts advising politicians often end up tayloring their advice to what the pollies want to do.
In Australia the common advice from the authorities is for the plebs to restrict wearing masks to those who have the virus.
