World Travel City Photography

Even within the English-speaking world there is no one standard definition of a city: the term may be used either for a town possessing city status; for an urban locality exceeding an arbitrary population size; for a town dominating other towns with particular regional economic or administrative significance. In British English city is reserved for very large settlements, smaller ones are called town or village. In the US city is used for much smaller settlements.
Although city can refer to an agglomeration including suburban and satellite areas, the term is not usually applied to a conurbation (cluster) of distinct urban places, nor for a wider metropolitan area including more than one city, each acting as a focus for parts of the area. And the word "town" (also "downtown") may mean the center of the city.
• Australia
In Australia, city in its broadest terms refers simply to any town that is large enough. Narrower usage can refer to a local government area, or colloquially to the central business district (CBD) of a large urban area. For instance the City of South Perth is a local government area within the wider urban area known as Perth, commonly called Australia's fourth largest city. Residents of Sydney might speak of travelling to the CBD as "going to the city". Australia's largest cities are Sydney, Melbourne, Brisbane, Perth and Adelaide.
