Heard Island and McDonald Islands are located in the southern waters of Australia. Due to the lack of different species of flora and fauna and human impact, they possess relatively rare pristine island ecosystems on Earth, making them of high conservation value.

Heard Island is considered one of the few Antarctic regions unaffected by alien species, with significant scientific value. The island is covered by ice and snow up to 80%. McDonald Island consists of many small rocky islets with sparse soil. Both islands have a cold temperate maritime climate with strong westerly winds. The landscapes of both islands are beautiful, untouched by human disturbance, showcasing the evolutionary processes of biology and geography.

Heard Island and McDonald Island are typical small, ancient subantarctic island groups, home to primitive and limited but numerous species. The islands have volcanoes, glaciers, and karst topography, with distinct coastal features. Compared to other Antarctic island groups, their ecosystems have been minimally affected. The species on the islands are scarce, and Heard Island is a paradise for burrow-nesting seabirds such as petrels. The breeding of seabirds and mammals is stable here.
