As a Tasmanian local and someone involved in the tourist industry I would have the following suggestions regarding best times to travel and where to go on a 1-3 week trip around Tassie. Tasmania has a cool temperate climate. This means to doesn't get really really cold or really really hot, but stays a pleasant temperature. It has 4 distinct seasons and all are lovely. In this town on the southern edge of Australia’s smallest state, there’s new art and new style, but the old brewery is still up the mountain. http://travel.nytimes.com/travel/guides/australia-and-pacific/australia/tasmania/where-to-go.html
