I am in Melbourne so don't have much choice but I'm another who wouldn't consider going to a game this season unless things change drastically, even if was in QLD or NSW. Mostly for the reasons people have already listed, public transport, sitting near randoms at the stadium, work, health etc.
Plenty of people couldn't afford the time off work or wouldn't want to eat in to 2 weeks+ of their sick leave. Not least of all the risk of severe illness or death that this thing can cause will hang over people's heads for quite a while yet.
Crowds getting anywhere near back to normal any time soon is probably wishful thinking.
