The body of water that separates Asia from Australia is the Arafura Sea. This sea is located between the northern coast of Australia and the southern coast of New Guinea. The Arafura Sea connects with the Timor Sea to the west and the Coral Sea to the east, playing a significant role in maritime shipping routes and regional ecology. Its waters are rich in marine biodiversity, making it vital for fishing and tourism activities. The sea also serves as a cultural boundary reflecting the diverse populations of nearby regions.
