History Speakers of Air Matoa originally lived in a village of the same name prior to 1976; they relocated to Rurumo, located on the coast of , in order to "improve their mobility". Following their move, Air Matoa became displaced by Yeresiam, an Austronesian language; as a result, only a single speaker of Air Matoa was left by 2008. In 2010, the speaker was reported by Anthonius Maturbong of the Papua Language Bureau to be an elder. According to residents of Rurumo, the last speaker of Air Matoa died in 2017, rendering the language extinct. Its extinction followed that of other Indonesian languages such as Tandia, Mapia, and Mawes.
