Hi Aaron
There is usually plenty to do in Hobart but I hear the place closes down for public holidays. Someone else may be more knowledgeable than me on that, I haven't been there over a long weekend. We like to look at the boats, go for a cruise, check out the old buildings, the botanic gardens, Casino if it's your thing. I personally think the weekend markets are overrated, but I love the Greek Taverna at Salamanca and the atmosphere at the old pubs. My friend swears by the brewery for great seafood but I haven't been there myself.
If you have a car, there is Russell Falls about one hour's drive away, north-west past New Norfolk. South you have the Huon region with Hartz and other wineries and east is Port Arthur two hours away but right past where the fires were. One hour north-east is the historic (touristy) town of Richmond, great food at the bakeries.
Doesn't seem to be any cricket this weekend. The One Day was today in Hobart.
