- Usage note: In Australia, "suburbs" are the official postal subdivisions of a city. Inner suburbs are subdivisions within the denser urban areas of the cities and outer suburbs are the postal divisions found in the outer rings of the metropolitan areas, and usually lying within the boundaries of a separate municipality. This differs from British and North American usage, in which the term "suburb" is never applied to central neighbourhoods.
