The Nuaulu tribe are divided into two groups, namely the northern and the southern groups. Numbering at a total of 2500 people, they inhabit in the Amahai district of Central Seram. The Northern Nuaulu inhabit in two villages on the north coast of central Seram Island, whlist the Southern group inhabit six villages on the south coast and interior of Amahai District.

Ethnically related to the Manusela, they are similar to the Manusela in language and follow the Naurus faith. However, they do not follow any form of Hinduism, though traces of Hinduism might be found in their rituals. They are more inclined to Christianity than the Manusela in faith, though they still adhere to their Animist Naurus faith at the same time.
