I am planning most of my activities around Hobart for my 6 days self drive in Tasmania, family of 5 including 3 children. Arriving 22 November 2011. May I know if we are able to see any Platypus near Hobart? Between Barilla Bay Oyster farm tour and Freycinet Marine Farm, which one is more worth visiting? Will there be any Abalone farm tour near Hobart, say the Tas Live Abalone, any tour available?
