Mackay (/məˈkaɪ/) is a city and its centre suburb in the Mackay Region on the eastern coast of Queensland, Australia. It is located about 970 kilometres (603 mi) north of Brisbane, on the Pioneer River. Mackay is nicknamed the sugar capital of Australia because its region produces more than a third of Australia's cane sugar.
There is controversy about the location of the region for administrative purposes, with most people referring to it as a part of either Central Queensland or North Queensland. Indeed, much confusion lies within the Queensland Government, with government services being provided through both Townsville (North Queensland) and Rockhampton (Central Queensland). Generally, the area is known as the Mackay–Whitsunday Region.
