My vote would be Tassie too. But I'm biased, I am in love with Tassie - infact, going there in about a month. I've been there about six times in the last three years and keep annoying all my girlfriends with far-fetched plans to move there and constantly looking at real estate sites.

Anyhow, you don't have to do heaps of walking - I'm happy pottering about in Hobart having great food overlooking the harbour. No-one would claim there is great shopping in Hobart but there's probably a few interesting shops in Salamanca. You could also indulge any preggy cravings with the Cadburys tour. Take a cruise on the Derwent. Spend a day at Port Arthur. Maybe mosey up to Strahan. Go on the railway thingy through the forest which is meant to be spectacular. Potter about in Richmond. The drive to Launceston is not too far either and I think Launceston is very pretty too. As is Freycinet of course. And Bicheno.

As I said, I'm biased and I've never been to the Whitsundays/Vanuatu but lying on a beach or by the pool in the heat when pregnant would not be my idea of fun. But I'm not a beach person at the best of times.
