Architecture of Australia

Architecture of Australia has generally been consistent with architectural trends in the wider Western world, with some special adaptations to compensate for distinctive Australian climatic and cultural factors. Indigenous Australians produced a wide range of structures and places prior to colonisation. Contemporary Indigenous practitioners are active in a broad range of built environment fields. During Australia's early Western history, it was a collection of British colonies in which architectural styles were strongly influenced by British designs. However, the unique climate of Australia necessitated adaptations, and 20th-century trends reflected the increasing influence of American urban designs and a diversification of the cultural tastes and requirements of an increasingly multicultural Australian society.

Notable Australian architectural adaptations include the Queenslander and Federation styles of residential architecture. Iconic Australian designs include the UNESCO listed Sydney Opera House, Melbourne Royal Exhibition Building, Brisbane City Hall and the 11 remnant penal colony sites selected for World Heritage protection in 2010.
