My husband and I are planning a 3 week trip to Western Australia in December. I've read some of the forum posts and am a bit overwhelmed. I know the state is vast, but after a very long trip from the U.S. Pacific Northwest, we would like to start in the Coral Bay area, beginning on Dec. 12, for diving, and then go somewhere else farther south, winding up in the Perth/Freemantle area with friends there for New Year's. I've read all through Lonely Planet's Australia guide, and I would really appreciate some guidance as to what best to do, and how to get from place to place. Thanks for any help!
