Indonesia lies between the mainland of South-East Asia and Australia in the Indian and Pacific oceans. It is the world’s largest archipelago state. Indonesia is made up of five main islands – Sumatra, Java, Sulawesi, Kalimantan (part of the island of Borneo) and Irian Jaya (the western half of New Guinea) – and 30 smaller archipelagos. In total, the Indonesian archipelago consists of about 17,508 islands; 6000 of these are inhabited and stretch over 4828km (3000 miles), most lying in a volcanic belt with more than 300 volcanoes, the great majority of which are extinct. The landscape varies from island to island, ranging from high mountains and plateaux to coastal lowlands and alluvial belts.
