I was there recently. Very recently. Take the drive up to Mount Wellington 4380 feet according to my Casio watch.
Also go to MONA (aka the museum of WTF???????) I don't really like museums. Loved this one. It's, ah, out there, man. Just go. You can get a boat there, if driving, go early. Must book online.
Port Arthur is certainly a must do day trip.Take your own lunch, or there's a coffee van up top of the hill up the back, rather ordinary.
Not a mask in sight, (after you escape the airport) business as usual in Tasmania, nothing to see here, move along....
They even take Australian dollars!
