The Territory of Christmas Island is a territory of Australia in the Indian Ocean, composed solely of that island. It has a population of 2,072 residents who live in a number of "settlement areas" on the northern tip of the island: Flying Fish Cove (also known as Kampong), Silver City, Poon Saan, and Drumsite. The majority of the population are Chinese Australian. It is called "Christmas Island" because it was discovered on Christmas Day (25 December 1643).
