According to the Australian Bureau of Statistics (June 2021 data), Hamilton Island—a premier resort destination in the Whitsunday Islands—has a permanent population of 1,225 residents.
Hamilton Island's population figure represents permanent residents only. The island's actual human presence fluctuates dramatically due to its nature as a tourism hub:
Hamilton Island is a continental island (not a coral cay), formed from the same geological processes as the mainland. It's the largest inhabited island in the Whitsundays and the only one with a commercial airport (HTI), making it the primary gateway to the Great Barrier Reef Marine Park.
The island operates under a unique leasehold structure within the Whitsunday Regional Council area. Most land is leased from the federal government, with the Hamilton Island Enterprises managing development and operations.
