Australia is bounded by the Timor Sea, the Arafura Sea and Torres Strait; on the E.
And 130° 50' and 151° 30' E., separated from Australia by Torres Strait and having the Arafura Sea on the south-west.
Amongst the islands of the Malay Archipelago are a number of enclosed areas - the Sulu, Celebes, Java, Banda and Arafura seas.
The Arafura Sea extends eastwards to Torres Strait, and beyond the strait is the Coral Sea, bounded by New Guinea, the islands of Melanesia and north-eastern Australia.
Timor lies in deep water a little to the west of the hundred fathom line, which marks in this direction the proper limit of the shallow Arafura Sea, extending between it and northern Australia.
Owing to the deep water between Timor and the Arafura Sea, the fauna of Timor presents scarcely any Australian types beyond a marsupial cuscus.
