This comprehensive scuba diving guide offers the most important, up-to-date diving and travel advice necessary to make every diving experience in Australia's Great Barrier Reef an unforgettable one. The finest dive sites in the region from Kelso Reef and the Cairns area in the north to Heron Island in the south are examined in detail. Full-color, three-dimensional maps of each dive site offer what no book has ever before provided: the information needed to plan your dive down to the last detail. You can review the exact layout of the site -- including depths, sizes, and distances between reefs and wrecks and any hazards -- and the lighting conditions for optimum underwater photography. The short chapters covering the 27 dives in this book provide crucial data about depth, currents, weather variables, and plant and animal life; and the book ends with a full-color visual encyclopedia of the most common fish in the area.
