Hi Charis, we were there for around 7 days too, then in Mel for 3. We did F&E, didn't drive (cos I dun wanna get us killed
), but joined various day tours. I liked joining different small groups cos more interaction and meet many people, very interesting.
The tours we joined are as follows for your reference:
Show You Tasmania Tours - Evening tour of Hobart, interesting and inside view of the city. But it was our 1st day, so I was tired didn't pay much attention...
Bottom Bit Bus Tours - Freycinet tour, and Port Arthur tour. This is a small new start up. Phil is very nice, but more chauffeur then guide cos he still learning the ropes. But fun, and cheap, mostly young backpackers.
BackTrack Tassie Tours - Heritage Highway tour, Tamar Valley & NE highlights. We got Ray to ourselves for the 2 days, so we gotta do the tour however we like. Ray is very knowledgeable about Tasmania.
Good guide. He can customized the itinery however you like, but do listen to his advise and recommendation, you wouldn't regret it. BTW, his 4WD is new, ah the smell of a new car...
Tiger Wilderness Tour - Cradle Mt. tour. Lee does a very good and lively tour. Had a good time with him, even with the rain. Personally feel that their itinery is more worthwhile compared to other Cradle Mt tours.
Tour With A Difference - Great Ocean Road Experience. This is a very good company. Really like their tour.
Their links you can find a couple of pages back on one of my post.
I would recommend you start either at Launceston, or Hobart, and travel to either via the East Coast Escape route with an overnight in Bicheno for the penguins (I really really regret missing that
). Must schedule for Saturday at Hobart for Salamanca Market! Buy your souvenirs here, Melbourne is more expensive, even at Queen Victoria Market.
