Australian non-residential architectural styles are a set of Australian architectural styles that apply to buildings used for purposes other than residence and have been around only since the first colonial government buildings of early European settlement of Australia in 1788.

Australian residential architectural styles have evolved significantly over time, from the early days of structures made from relatively cheap and imported corrugated iron to more sophisticated styles borrowed from other countries, such as the California bungalow from the United States, the Georgian style from Europe and Northern America, and the Victorian style from the United Kingdom. A common feature of the Australian home is the use of fencing in front gardens, also common in both the United Kingdom and the United States.
