Southern Islands (group of isles south of Singapore)

Main islands and features

• Sentosa — a purpose-developed resort and attractions island with beach areas and transportation links to the main island.
• St John's Island and Lazarus Island — neighbouring isles known for beaches, picnic recreation and historical uses.
• Kusu Island — a small island with shrines and seasonal visits by devotees and holidaymakers.
• Sisters' Islands and adjacent reefs — notable for marine life and included in Singapore's coastal conservation measures.
• Smaller islets such as Pulau Hantu, Pulau Brani and other offshore features used variously for industry, navigation and nature.

These islands present contrasting characters: some are built up for tourism and industry, others are managed for conservation or left largely natural. Many attract day-trippers, divers and anglers while a few remain off-limits for safety or protection reasons.

History and development

The Southern Islands have long been part of local maritime routes and coastal life. Over the 19th and 20th centuries several islands served practical roles such as quarantine stations, military outposts and small settlements. From the late 20th century onward Singapore developed parts of the group for leisure, port activity and energy infrastructure, while also setting aside areas for research and environmental protection.

Uses, conservation and significance

Today the islands are valued for tourism (resorts, beaches and attractions), scientific study, and recreation. Marine habitats around some islets have received formal protection to conserve coral communities and reef species; for example, the region around the Sisters' Islands has been a focus of marine-park efforts. Management balances public access, heritage observance and environmental safeguards.

The cluster illustrates how a small nation combines economic use, leisure development and environmental stewardship in a compact maritime setting.
