Kusu Island is one of the Southern Islands in Singapore, located about 5.6 kilometres to the south of the main island of Singapore, off the Straits of Singapore. The name means "Tortoise Island" or "Turtle Island" in Chinese; the island is also known as Peak Island or Pulau Tembakul in Malay. From two tiny outcrops on a reef, the island was enlarged and transformed into an island holiday resort of 85,000 square metres.
