There’s much to see in the South Pacific. Australia has the Great Barrier Reef, while Fiji stuns with its colorful soft corals. On the other hand, you’ll find a Ghost Fleet of World War II wrecks in Chuuk (Truk) Lagoon and the very sharky Blue Corner in Palau. There’s also the manta rays of Yap and the whales of New Zealand. Papua New Guinea boasts more WWII wrecks as well as outstanding biodiversity, and the little-visited Solomon Islands are a beacon for eco-tourism. French Polynesia, Tonga and Vanuatu round out the list of South Pacific liveaboard destinations. Typical itineraries in the area last from 6 to 14 nights, and the best time to dive is from August to April.
