Antarctica is home only to scientists, and for short periods of time. These scientists live in the "bases" developed by their countries.
Because Antarctica has no permanent resident population and belongs to no single nation, it would depend which base you were on. The Australian and UK bases would call him Father Christmas, and the US bases would call him Santa Claus.
Australia supports research stations on Antarctica named Casey station, Davis station, Macquarie island station and Mawson station.
