Early in the pandemic there was an outbreak in TAS... later VIC, NSW, SA had their turn, then QLD. Only a matter of time for WA/ACT/NT - the challenge will be, particularly for WA - if there is an outbreak, is how their systems will cope. They haven't really been 'stress tested'. The population doesn't appear to be in a pandemic mindset. I would argue there are similar concerns for the NT with a large indigenous population, or ACT with a very small hospital system and very mobile community...
