When we went to NZ a couple of years ago, I loved the "My Travel Planner" feature on the www.newzealand.com website. It was great to be able to move around elements of our trip, and see how it affected the whole itinerary.

I've been searching for something similar for our upcoming trip to Australia, but haven't had any luck. I know about http://www.whereis.com for general directions/distance planning, but I haven't found anything that ties it all together in a general itinerary/travel planner. Does such a thing exist?

Thanks!
