Southeast Asian island (5)
I believe the answer is:

This is all the clue.
(Other definitions for timor that I've seen before include "Eastern island" , "SE Asian island" , "Island of the Malay Archipelago" , "Island north of Australia" , "East . . . . ., became independent of Indonesia in 2002" .)
