The Mackay region also includes around 100 square kilometres of islands and over 25,500 square kilometres of vast ocean. The area includes the islands of Brampton, Keswick, St Bees and Lindeman and is home to the southern part of the most spectacular natural wonder, the Great Barrier Reef. Ideally located on the coastline where the Pioneer River meets the mystifying Coral Sea, Mackay’s natural beauty is an Australian asset.
