use of sugar cane for different purposes. These include a planned energy co-generation plant that could deliver up to 30 per cent of Mackay's annual electricity supply. Tourism Compared to many of its neighbouring cities and regions in Queensland, Mackay's tourism industry is small and still developing. This is despite being close to notable attractions including Eungella National Park, the Great Barrier Reef, and the Whitsunday Islands. Latest figures indicate about 685,000 domestic and international visitors come to the region annually. More telling, however, is that domestic and international visitor night stays have increased to 2.7 million annually, an increase of nearly 1 million since 2000. Several new hotels have opened in the region since 2000, further indication of a growing industry. These include The Clarion International, Quest Serviced Apartments and the Ibis Mackay Airport. Marine Like tourism, the marine industry in Mackay is small but has a lot of potential. Mackay is well situated to become a major service centre for the marine industry, being in immediate proximity to the Whitsundays, and located halfway between Brisbane and Cairns. Currently the Mackay Marina is the largest base in the district for the maintenance, refit and related services for all marine craft, particularly Super Yachts. The Mackay Whitsunday Super Yacht Cluster, a group of regional companies focusing on providing integrated repair, refit and provisioning for the increasing number of visiting super yachts, was established in 2001 to support and promote the development of this sector. Retail Mackay has three main shopping centres. Caneland Central is the largest of these, with more than 130 speciality stores. Myer is among the new anchor tenants. This expansion was opened on 13 October 2011. Mount Pleasant Shopping Centre is the second major shopping centre in the Mackay region. It hosts department stores, supermarkets and other speciality outlets. Outside the main centre, a number of bulky-good outlets also operate, along with a six-screen Birch Carroll and Coyle cinema complex. The Mackay City Heart, located in the older city centre, is also another thriving part of the city. It is the home of many of the region's banks, law, accounting and other professional service firms.
