The official symbols of the City of Sydney have a rich history.
Over the years the City has changed its Coat of Arms - the first version included a shield supported on one side by an Aboriginal man, and on the other by a British sailor.
The City's flag includes the shield from the Arms granted by the College of Arms in London on 30 July 1908.
Sydney has its own official flower - the Banksia ericifolia was officially adopted in 1992 as part of the sesqui celebrations of Council, serving as a symbol of Australia's oldest city.
The granting of the Key to the City is a symbolic presentation that represents the highest honour a city can confer on an individual or an organisation.
