Like you I am blessed to be in Tassie, and thank my/ our lucky stars that we've been spared from the COVID shitshow that most of the rest of Australia has had to endure, especially when we had the first serious lockdown over it back in the Ruby Princess day. I reckon though that it's pretty hopeful if you assume it won't make it back here due to good governance. It'll only take one case, e.g. through some flight attendant up in QLD and we'll be in complete lockdown given the situation with the health system here.
Regarding AZ, you are entitled to your opinions, but one thing I would say with the greatest of respect is that if you are 44 and haven't had a Fizzler shot yet, I don't think you've been trying particularly hard to get one. I know of numerous people in their 30s who've already got a shot, some of whom booked last week and received them within the last couple of days.
