The Great Barrier Reef has lost half its corals in the past three decades. "A vibrant coral population has millions of small, baby corals, as well as many large ones— the big mamas who produce most of the larvae," he said. The branching and table-shaped corals provide the structures important for reef inhabitants such as fish. This peak season offers some key advantages for travelers.
