Along withLelepa, it creates the harbour at northEfate known asPort Havannah. This harbour was a focal point duringWorld War II, with many troops stationed there, including posts on Moso itself. Today, small tokens of the soldiers' presence can still be seen on Moso.

Seven villages were originally scattered throughout Moso until missionaries facilitated their formation into one coastal village, Sunae. This community was divided in two in the early 1990s and some people split from Sunae, forming Tassirki village on central Moso.

There are no roads or cars on Moso.

Access to the island is viabanana boat from Tanoliu village in North EastEfate.

The Tasiriki community, in conjunction withWan Smolbag Theatre, is the base for a turtle monitoring programme on northwestern Efate. The project is run throughout Vanuatu with the goal of preserving the endangered turtle species found in the Pacific. The community operates a bungalow that accommodates volunteers who stay for short-term periods assisting the locals with the turtle monitoring programme.

Sunae community is attempting to initiate a small tour business to the eastern part of the island as part of a community development project. This part of the island is where parts ofLes Aventuriers de Koh-Lanta, the French version of theSurvivor TV series, were filmed.
