Mawng (N64) is a non-Pama Nyungan language from Warruwi, also known as South Goulburn Island, north-west Arnhem Land. Mawng is the main language on Warruwi, other languages include Kun-barlang N69, Kunwinjku N65 and Yolngu Matha N234, Torres Strait Creole P2 and English . Manangkarri N183 is the language originally spoken on the two Goulburn Islands, possibly on Weyirra (North Goulburn Island); Manangkarri and Mawng are probably in a dialectal relationship (Singer, 2006, pc).

Mawng is spoken in the western part of Arnhem Land in the Northern Territory, Australia. Speakers today identify Mawng as the language of Warruwi (South Goulburn Island), Weyirra (North Goulburn Island) and an area on the mainland coast opposite the islands. Most Mawng speakers live at Warruwi Community, but others live at nearby communities such as Minjilang (Croker Island), Gunbalanya, Maningrida and in Darwin. Mawng is spoken by around 400 people and is still being learned by children. Warruwi School runs a Mawng language program and supports the Warruwi Language Centre which runs other Mawng language activities, including Mawng literacy training. In 2014 The Warruwi Language Centre was set up on Warruwi. In a little building near the school linguists worked with the school and community members to create a quiet space where recordings can be made and listened to. Community members are working with linguists to revive and create Mawng literacy materials for reading and writing in Mawng (https://www.mawngngaralk.org.au/language/).

Singer et al. (2001:1) say that Mawng has a close linguistic relationship with Iwaidja N39; they are the only languages in the Iwaidjan language family still spoken, the other languages in this family are Amurdak N47, Marrku N45, Wurrugu N37, Ilgar N184 and Garig N188. Mawng is spoken by around 400 people and is still being learned by children.
