The Sunda Islands are part of the Malay archipelago. They are divided into the Greater Sunda Islands and the Lesser Sunda Islands. Sumatra, Java, Borneo and Sulawesi make up the Greater Sunda Islands. The Lesser Sunda Islands consist of many smaller islands. Today, the Sunda Islands are divided between Indonesia, Malaysia, Brunei and East Timor. The Wallace Line also runs through the Sunda Islands. It is the biological division between the Australian fauna and flora, and that of Southeast Asia.
