People live in Antarctica to do scientific research.

Australia has 3 permanent stations in Antarctica (Davis, Casey and Mawson) and one on sub-Antarctic Macquarie Island. The expeditioners who live on these stations conduct research in atmospheric studies, biology (including plants and animals), glaciology, medicine, human impact and environment.

Tradespeople also live at the stations. These include plumbers, electricians, mechanics and carpenters. They keep the stations running and support the scientific research.
