The sub-Antarctic Botanical Gardens, located within the Royal Botanic Gardens of Tasmania, displays plants unique to the high-latitude sub-Antarctic islands, while the cold mist reflects the humid and cold living environment of its remote homes. These plants, mainly from Macquarie Island, were collected by the scientists during field trips to Macquarie Island. Macquarie Island is a small island in southern Tasmania, which is between Australia and Antarctica and belongs to the sub-Antarctic climate and geographical environment. Walking into the museum, you can hear the sounds of simulated wildlife on Macquarie Island, including seals, penguins, albatrosses, and endless sounds of wind and rain, giving you the illusion of being in the Antarctic. The Sub-Antarctic Botanical Garden, with the assistance of the Australian Antarctic Foundation, Hobart City Council and Friends of the Royal Botanic Garden of Tasmania, opened to the public on October 13, 2000. The botanical museum aims to replicate the appearance and environmental conditions of Macquarie Island and serves as a laboratory for plant cultivation in the region. The arc-shaped interior wall features murals depicting the various environments of the island, while the landscape is decorated with plants, mosses and rocks collected from Macquarie Island.
