The heartland of the Bunak is located in the middle east of the East Timorese area of Bobonaro and north east of the municipality of Cova Lima District. Here is the only place where place names of Bunak origin are to be found, while in other areas inhabited by the Bunak there are also place names of Austronesian origin. Bunak settlements in bordering territories only have Austronesian place names. This indicates that the original homeland of the Bunak people lies in the center of the territory where the Bunak now cover.
