The black swan (Cygnus atratus) is widely referenced in Australian culture, although the character of that importance historically diverges between the prosaic in the east and the symbolic in the west. The black swan is also of spiritual significance in the traditional histories of many Aboriginal Australian peoples across southern Australia. Metaphoric references to black swans have appeared in European culture since long before Europeans became aware of Cygnus atratus in Australia in the 18th century.
The black swan is the official state emblem of Western Australia and is depicted on the flag and coat of arms of Western Australia. The symbol is used in other emblems, coins, logos, mascots and in the naming of sports teams.
