Heard Island, Antarctica
Heard Island is a remote, uninhabited island located in the Southern Indian Ocean. It is the only active volcano in Australian territory and is home to a variety of unique wildlife.
It is also home to the Mawson research station, which was established in 1947. The island is of great scientific interest due to its unique environment and biodiversity. Unfortunately, the island is no longer open to the public due to its remote location and the need to protect its fragile environment.
