The McDonald Islands are uninhabited and have a population of zero. These small, remote islands are situated in the Southern Indian Ocean and are part of Australia’s external territories. They are primarily known for their rugged terrain and harsh environmental conditions that make human habitation impossible.
Due to their isolation and the lack of resources such as fresh water and arable land, no permanent residents live on the islands. They are mainly visited by researchers and scientists studying the unique ecosystems and wildlife found in this part of the world and are not developed for tourism or residency. As a result, while the islands hold ecological significance, they remain unpopulated.
