Mussau
The Mussau are the people of the small, remote St Matthias or Mussau group, ten low islands north-west of New Ireland in the Bismarck Archipelago, of which hilly, rainforest-covered Mussau is the largest. They speak Mussau-Emira, an Oceanic language of the Austronesian family shared with neighbouring Emirau, while the Tenis language of Tench Island forms the other member of the St Matthias subgroup.
