The early Anglo-Celtic immigrants of the 18th and 19th centuries introduced folk ballad traditions which were adapted to Australian themes: "Bound for Botany Bay" tells of the voyage of British convicts to Sydney, "The Wild Colonial Boy" evokes the spirit of the bushrangers, and "Click Go the Shears" speaks of the life of Australian shearers. The lyrics of Australia's best-known folk song, "Waltzing Matilda", were written by the bush poet Banjo Paterson in 1895. This song remains popular and is regarded as "the nation's unofficial national anthem".
