What are Singapore main geographical points according to this text? Bullet point please.

Context:
Singapore consists of 63 islands, including the main island, Pulau Ujong. There are two man-made connections to Johor, Malaysia: the Johor–Singapore Causeway in the north and the Tuas Second Link in the west. Jurong Island, Pulau Tekong, Pulau Ubin and Sentosa are the largest of Singapore's smaller islands. The highest natural point is Bukit Timah Hill at 163.63 m (537 ft). Under British rule, Christmas Island and the Cocos Islands were part of Singapore, and both were transferred to Australia in 1957. Pedra Branca is the nation's easternmost point.

Land reclamation projects have increased Singapore's land area from 580 km2 (220 sq mi) in the 1960s to 710 km2 (270 sq mi) by 2015, an increase of some 22% (130 km2). The country is projected to reclaim another 56 km2 (20 sq mi). Some projects involve merging smaller islands through land reclamation to form larger, more functional and habitable islands, as has been done with Jurong Island. The type of sand used in reclamation is found in rivers and beaches, rather than deserts, and is in great demand worldwide. In 2010 Singapore imported almost 15 million tons of sand for its projects, the demand being such that Indonesia, Malaysia, and Vietnam have all restricted or barred the export of sand to Singapore in recent years. As a result, in 2016 Singapore switched to using polders for reclamation, in which an area is enclosed and then pumped dry.<|im_end|>
