The name Indonesia has its roots in two Greek words: "Indos" meaning Indian and "Nesos" which means islands. It is an appropriate description of the archipelago as there are estimated to be a total of 17,508 islands, of which only about 6,000 are inhabited, stretching for 5,150 km between the Australian and Asian continental mainlands and dividing the Pacific and Indian Oceans at the Equator.

Five main islands and 30 smaller archipelagoes are home to the majority of the population. The main islands are Sumatra (473,606 sq.km), Kalimantan 1539,400 sq.km), Sulawesi l 189,216 sq. km), Irian Jaya (421,981 sq. km), and last but not least Java (132,187 sq.km), home to 70 percent of the country's population. Indonesia shares Irian Jaya with Papua New Guinea and two thirds of the island of Kalimantan with Malaysia and Borneo.

British naturalist A. R. Wallace (1823-1931) postulated an imaginary line (named after him Walace's Line) as the dividing line between Asiatic and Australian fauna. It passes between Bali and Lombok islands between Kalimantan and Sulawesi, then continues south of the Philippines and north of Hawaii.

This theory probably explains the presence of species of fauna familiar to both Asia and Australia found in Indonesia. However, there are species indigenous to Indonesia, like the "orang utan" apes of Sumatra and Kalimantan, the giant "komodo" lizards which are the only ones of their kind in the world today roaming free on the island of Komodo; the one homed rhinoceros of Java, the wild "banteng" oxen, tigers and many other species which are now protected in wildlife reserves.

Indonesia's climate is definitely tropical. There is no Autumn or Winter and distinctive "dry" and "wet" seasons share the year. The East Monsoon, from June to September, brings dry weather while the West Monsoon, from December to March is moistureladen, bringing rain.

The transitional period between these two seasons is interspersed by the occasional heavy rain shower, but even in the midst of the West Monsson season, temperatures range from 21 C (70 F) to 33 C (91 F) except at higher altitudes which can be much cooler. Heaviest rainfalls are usually recorded in December and January and humidity is generally between 75% and 100%.
