Dive World War II wrecks and a coastal reef teeming with fish in balmy Darwin Harbour. Approximately every second week, the tidal currents let you discover these underwater secrets. Swim through moss-covered hulks of ships, sunk in 1942 air raids, and now home to coral trout, wobbegong sharks, jewfish and barracuda. See gorgonians, soft coral trees, harp corals, vase sponges and ascidians in the shallow reefs lining either side of the harbour. Experience one of Darwin’s famous flamingo sunsets before a night dive in the warm, glass-smooth seas. You’ll spot slate pencil urchins and the occasional octopus in the naturally illuminated water.
