West Antarctica is south of the Americas, part of what is normally called the Western World. East Antarctica is mostly south of Asia, sometimes known as the East. Australia is north of the edge of East Antarctica, so its western side is north of East Antarctica, and its eastern side is north(ish) of West Antarctica.
