I have never taken the GCT trip to Australia, New Zealand and Fiji, but it looks and sounds wonderful. I did go independently to Australia and New Zealand with a friend. Four times! We loved it so much, we went every other year for eight years until she was unable to travel. There is so much to see, and the people are so nice.
I can't believe that a company whose trips I have always enjoyed could fall down on a trip to a place I have loved. If he doesn't come up with some definite reasonings behind his post, we should all disregard it.
And to Sue. If you can get to Tasmania, you will enjoy it. The scenery is more like New Zealand than other parts of Australia, and the history is very interesting. Try to be in Hobart near the Salamanca area and waterfront. There is a street fair one day a week, I think, that has nice stuff. I bought a pair of earrings and a spoon rest for my kitchen. And there are good restaurants in that area.
