I love this place so much, I've been there four times! Though it's a 14 hour flight from where I live, it's easy once you're there. Sydney is one of my favorite cities in the world, and the countryside is phenomenal too.
Everyone now knows New Zealand because it's where "The Lord of the Rings" and "Hobbit" movies were filmed, but I visited it even before then. I think this is one of the two prettiest places in the world. (Chile is the other one). It's full of action-adventure too!
I got to live on a tropical island (in a tent!) for a month in 2001, working on a television show. The kids were not used to seeing a television crew, that's for sure!
