Direction Island is an uninhabited coral islet in the Cocos (Keeling) Islands, an Australian territory in the Indian Ocean halfway between Perth and Sri Lanka, with a beach of white sand 300 metres long and a tidal channel called the Rip that carries swimmers from the open ocean into the lagoon on the flooding tide, and it is reached by ferry across the lagoon from West Island a few days a week, with no airstrip and no residents. The atoll is a ring of 27 islets around a lagoon, and Direction Island sits at the gap where the ocean enters, so that the flooding tide drives the open sea through the channel between it and neighbouring Prison Island and the snorkeller rides it in, over coral and past reef sharks, turtles and schools of fish moving with the current, a drift of a few minutes that is repeated by walking back along the sand; the green turtles grazing the seagrass in the lagoon are not passing through but a population that breeds here and belongs nowhere else, and the beach, Cossies, has thatched pondok shelters standing back in the shade, each first-come and free, with a wood-fired barbecue nearby.
The island had a cable station in 1914, when the German cruiser Emden landed a raiding party of fifty men to destroy it and was caught and wrecked by HMAS Sydney offshore in the first naval battle of the war; the raiding party, still ashore, seized a schooner and sailed away rather than surrender, and the heritage trail through the coconut palms passes the remains of the station. The palms are the plantation of the Clunies-Ross family, who ruled the atoll as their own for 150 years until 1978, and the Cocos Malay people of Home Island, descended from their workers, run the ferry. September and October are the driest and clearest months, and the cyclone season squalls can cancel a sailing. Direction Island is a beach on the way into a lagoon, and the tide does the swimming.
