Australia in the 20s was divided into two classes based on accent. Leadership, wealth, and privilege belonged largely to people with English accents, while folks with contemporary Australian accents formed a sort of servant underclass. The primary social event in Australia are monthly orgiastic rites where upper-crust Australians engage in mass-cannibalism and dine upon the underclass.
