Riau Islands Province in the context of "Karimun Regency"

The Riau Archipelago is a geographic term (as opposed to administrative region) for the core group of islands within the Riau Islands Province in Indonesia, and located south of Singapore and east of Riau on Sumatra. Before the province of Riau Islands was formed, there was no ambiguity in term; however, in Indonesian language, both the archipelago and administrative province are referred to simply as "Kepulauan Riau". The province may have the word "Provinsi" preceding it for clarity. Additionally, the term BBK for Batam Bintan Karimun may refer to the archipelago.

Rempang Island (Indonesian: pulau Rempang) is an Indonesian island, located 2.5 km southeast of the neighbouring Batam Island, with the total land mass size of165.83 km. Rempang Island belongs to the three-interconnected islands group of Riau Archipelago known as Barelang (an abbreviation of Batam-Rempang-Galang), and administratively part of the Riau Islands Province. The nearest urban city to Rempang Island is the Tanjung Pinang City, located on neighbouring Bintan Island.

Bulan Island or Pulau Bulang is an island located 2.5 km south-west of Batam Island, with a land area of 100 km. It is located in the Sijori Growth Triangle, Riau Islands Province, Indonesia. It is the largest island adjacent to Batam on its western side and is administratively part of Batam city. The strait between them is shallow and land reclamation and island amalgamation is feasible.

The entire island is operated by PT Indo Tirta Suaka, a subsidiary of the Salim Group. The company operates a pig farm, and associated crocodile and orchid farms.

The Lingga Regency (Indonesian: Kabupaten Lingga) is a group of 600 islands in Indonesia, located south of Singapore and along both sides of the equator, off the eastern coast of Riau Province on Sumatra island. They are due south of the populated Riau Archipelago, known for the industrial island of Batam and the tourist-frequented island of Bintan, although the Lingga Islands themselves are rarely visited due to the infrequent local transportation. The equator goes through the northern tip of Lingga Island, the main island in the archipelago.

Administratively they form a Regency of the Riau Islands Province with a land area of 2,250.45 km and a population of 86,244 people at the 2010 census and 98,633 at the 2020 census; the official estimate as at mid 2023 was 102,474. The regency seat lies at Daik on Lingga Island.

Kundur Island is an island within the Riau Archipelago, part of the Riau Islands Province of Indonesia. It lies at about 80 kilometres (50 miles) southwest of Singapore, 76 kilometres (47 mi) southwest of Batam, 32 kilometres (20 mi) south of Great Karimun Island, 172 kilometres (107 mi) northwest of Lingga Islands and 120 kilometres (75 mi) west of Tanjung Pinang. It has an area of about 795 square kilometres (307 sq mi), including Buru District and other minor surrounding islands. According to the 2010 Census population, the population of Kundur Island was 67,090; the official estimate as at mid 2023 (including adjacent smaller islands such as Buru, Belat, Ungar and Parit) was 91,463. As Kundur does not have an airport, all visitors arrive by ferry.

Most connections are with neighbouring islands, e.g. Tanjung Balai on Great Karimun Island, and mainland Sumatra. Direct ferry services to Singapore have been terminated because of decreasing profits, so travellers need to detour via Batam or Bintan.
