Advance Australia Fair was written by Scottish-born composer Peter Dodds McCormick and first performed in Sydney in 1878. It circulated for decades as a patriotic song before Australians voted for it in a 1977 plebiscite, and it was officially proclaimed the national anthem in 1984. A lyric change in 2021 altered the second line from young and free to one and free to better reflect Indigenous history. Online, the recording is shared on soundboards as a ready-made symbol of Australian identity for jokes, celebrations and sporting highlights.
