Imagine the following scenario: a tourist arrives for a short visit. He takes in the Asia World Expo, Disneyland, the Big Buddha and SkyCity, stays in a hotel at the airport and gets all his shopping done at SkyPlaza. He's had a swell time in Hong Kong - and he didn't even have to step off Lantau Island. Although it sounds extreme, and unlikely, Shih Wing-ching, chairman of property agency Centaline Group, contends it could be an attractive option for some travellers who stay only one or two days. But even he admits that Lantau, despite its transformation, could not eclipse Hong Kong Island in terms of attracting tourists. Lantau will be subject to further development under the government's concept plan, issued by a taskforce led by Financial Secretary Henry Tang Ying-yen. Proposals include a logistics park, a golf course, a theme park and a race course on the northern coast, and a spa resort in the south. The MTR Corporation is building a $950 million, 5.7km-long cable car line from Tung Chung to the Big Buddha at Ngong Ping in the hills of Lantau. But development demands do not stop there. Liberal Party chief James Tien Pei-chun proposes setting up a casino on the island solely for the use of tourists. Mr Shih also says the area should be further developed, because the Airport Express is under-utilised. Environmentalists, meanwhile, warn of pollution and destruction of habitats. Conservancy Association director Hung Wing-tat warns the run-off from developments could pollute the waters of Tai O, which is well known for its stilt houses. Lantau residents say they remain in the dark over development plans. Tung Chung residents have complained about the growing pollution from land development. The government is reviewing the Lantau Concept Plan to take in views submitted during the public consultation which ended in February. A spokeswoman says the review will be finished this year.
