Australian heraldry is the style and tradition of using armorial achievements, sometimes known as coats of arms, and other heraldic bearings and insignia in Australia.

It largely follows the Gallo-British tradition of heraldry also followed in England, Scotland, Ireland, Canada and New Zealand.

[2] In response to questions submitted by the Society, on 7 February 2018 prime minister Malcolm Turnbull stated:[3] I am advised by the Department of the Prime Minister and Cabinet that ... the practice of the College of Arms in England granting armorial bearings to Australians is well established as one way Australians can obtain heraldic insignia if they wish to do so.

There is nothing preventing any person or organisation from commissioning a local artist, graphics studio or heraldry specialist to design and produce a coat of arms or identifying symbol.

[4] The heraldry of Australia has added indigenous Australian animals to the existing heraldic bestiary, along with native plants and occasionally traditional motifs of Aboriginal Australians and Torres Strait Islanders.
