The FOUR BASES are:

The Macquarie Island Station (FIRST DAY OF ISSUE 30 NOV 2001) is a permanent Australian subantarctic research base on Macquarie Island, commonly called Macca, situated in the Southern Ocean and located approximately halfway between mainland Australia and Antarctica, managed by the Australian Antarctic Division. Scientific research on the island is focused around biology, geosciences, meteorology, and human impact on the environment.

Casey Station (FIRST DAY OF ISSUE 23 DEC 2001) is a base for scientific research programs. Since 2008, scientists based at Casey have contributed to research into study of the Law Dome, the bedrock geology and structure of the East Antarctic ice sheet and its glaciological processes. In more recent years, Casey has served as a base for marine biologists to examine changes to polar seafloor communities exposed to different carbon dioxide concentrations. Adélie penguin research is conducted at Casey. Scientists are also studying the influence of climate change and human impact on extensive and well developed moss beds that grow at and near Casey

Mawson Station (FIRST DAY OF ISSUE 9 JAN 2002) is a base for scientific research programs including an underground cosmic ray detector, various long-term meteorological aeronomy and geomagnetic studies, as well as ongoing conservation biology studies, in particular of nearby Auster rookery, a breeding ground for emperor penguins and Adélie penguins.

Davis Station (FIRST DAY OF ISSUE 11 FEB 2002) is a base for scientific research programs including the study of viruses and bacteria using molecular genetic techniques in glacial lakes, the impact of environmental change and pollution on Antarctic marine ecosystems, atmospheric research, measuring algae growth as an important food source for tiny marine herbivores such as zooplankton, the impact of climate change, including the increasing carbon dioxide concentrations on marine microbes and, together with researchers at Casey, the study of the Law Dome, the bedrock geology and structure of the East Antarctic ice sheet.
