Thanks Ian & Justin for your comments.
Darwin is a great place. I'm thinking of going back in the summer. They tell me it rains all the time so it should be interesting.
Chris I was there during the summer and I can only describe it as HOT.
It was like working in a sauna. Winter time is nice if you are not used to the humidity.
Thanks for the info Justin,
I love a good storm and casing them might provide a great photo oppertunity.
Staying in the air-con as much as possible should help.
