Southwest Maluku Regency
Southwest Maluku Regency is a regency of Maluku Province, Indonesia. Geographically it forms the most eastern portion of the Lesser Sunda Islands, although it has never been administratively included with them, and politically has always comprised a part of the Maluku Province. It comprises a number of islands and island groups in the south of the province, including Lirang Island, Wetar Island, Kisar Island, Romang Island, the Letti Islands, the Damer Islands, the Sermata Islands and the Babar Islands. The total land area is 4,581.06 km2, and the population was 70,714 at the 2010 Census and 81,928 at the 2020 Census; the official estimate as at mid 2024 was 95,746.
The administrative centre lies at Tiakur on Moa Island, but the largest town is Wonreli. These islands were originally part of Maluku Tenggara Regency within Maluku, and then from 4 October 1999 part of Maluku Tenggara Barat Regency when that was created, but from 24 June 2008 became a separate regency within Maluku.
Administrative districts
As at 2010 the Southwest Maluku Regency was administratively composed of eight districts. But by 2015 the number of districts had increased to seventeen by the splitting of existing districts, although by 2023 the names of several of these districts had been altered; Pulau Pulau Wetar has been divided into four districts - Wetar, Wetar Barat, Wetar Timur and Wetar Utara ; the other six newly created districts are Dawelor Dawera and Pulau Masela formed from parts of Babar Timur District, Kepulauan Roma and Kisar Utara formed from parts of Pulau Pulau Terselatan District, Pulau Lakor formed from part of Moa Lakor District, and Pulau Wetang formed from part of Pulau Pulau Babar District.The districts are formally grouped into three archipelagoes - the Terselatan Group, the Lemola Group and the Babar Group.
