[2] On the southern end of Sibu Besar Island, there is a small fishing village called Kampong Duku with a population of fewer than a hundred people (about 40 families).

The main leisure activities on the island are watersports such as snorkelling and diving, and numerous coral reefs are close to hand.

Most of the beach resorts are located on the eastern side of the main island.

Most of the resorts are closed during the annual 3-month monsoon period, save for those facing the mainland.

The island is only accessible by ferry from Tanjong Leman Jetty in Mersing Town.
