Macquarie Island.

Macquarie Island, situated 1,500 km southeast of Tasmania, is a geological marvel and a thriving wildlife sanctuary. As the only place on Earth where rocks from the mantle are exposed above sea level, it offers unparalleled insights into oceanic crust formation and plate dynamics. Spanning 34 km in length, the island boasts stunning landscapes shaped by the Southern Ocean, including steep escarpments, vibrant grasslands, and unique waterlogged peat beds. Home to over 850,000 breeding pairs of Royal Penguins and various seabird species, including albatrosses and King Penguins, it serves as a critical habitat for diverse wildlife. With a history that includes a research station established in 1948, Macquarie Island remains a vital site for scientific exploration and conservation in a pristine, remote environment.
