Travel Review: Vacation to Australia, New Zealand & Fiji, Port Douglas, Sydney, Queensland, Milford Sound, Great Barrier Reef

Add one more day at Port Douglas - we had so many activities there, we didn't have enough time just to enjoy the nice town.  

Maybe visit a different place along the GB Reef.  The place we stopped was not as colorful as we had expected.

If possible, spend less time in Kuranda.  The trips there (Gold class rail) and back (sky car) were great, but we had more time than we wanted in the town itself. Trading for more time in Port Douglas would have been preferred.
