Conditions have to be just right for corals to put on one of nature’s most spectacular events. Coral spawning on the Great Barrier Reef happens once a year, just after a full moon, when the winds are low and water is warm. Trillions of sperm and eggs get released into the water, creating a blizzard of activity.
