Apparently I had some kind of plastic box for my P&S camera while snorkeling at the reef. I took several underwater pictures of the coral, but this was my favorite.

Agincourt Reef (below, previous picture), off Port Douglas on the Great Barrier Reef, is a series of many smaller reefs with at least 16 different dive sites. The Channels offer interesting swim-throughs and caves, while The Gardens are renowned for their exceptional abundance of brightly colored reef fish. Blue Wonder is a breathtaking wall dive to beyond 40 meters, while Nursery Bommie is a spectacular pinnacle where pelagic fish gather to feed. (Queensland.com)
