My wife and I are going to Western Australia May 14-31st. We plan to fly into Perth and then head up to Ningaloo Reef for some whale sharks and diving. Are there any must do things we should plan to do during our 2.5 weeks? What dive shops do you recomend? Is there plenty to do on the west coast? Would it be pushing it to try to go to the east coast too? Where is the best place to swim with the wild dolphins?
