"Advance Australia Fair", written by Scottish-born composer Peter Dodds McCormick, officially replaced "God Save the Queen" as Australia's national anthem.

"Advance Australia Fair" is the national anthem of Australia. Written by Scottish-born Australian composer Peter Dodds McCormick, the song was first performed as a patriotic song in Australia in 1878. It replaced "God Save the Queen" as the official national anthem by the Whitlam government in 1974, following an indicative opinion survey. The subsequent Fraser government reinstated "God Save the Queen" as the national anthem in January 1976 alongside three other "national songs": "Advance Australia Fair", "Waltzing Matilda" and "Song of Australia". Later in 1977 a plebiscite to choose the "national song" preferred "Advance Australia Fair". This was subsequently proclaimed the national anthem in 1984 by the Hawke government. "God Save the Queen" became the royal anthem, and is used at public engagements attended by the King or members of the royal family.

Peter Dodds McCormick was an Australian schoolteacher and songwriter, known for composing the Australian national anthem, "Advance Australia Fair". He published under the pseudonym Amicus, Latin for "friend".

"God Save the King" is de facto the national anthem of the United Kingdom. It is one of two national anthems of New Zealand and the royal anthem of the Isle of Man, Australia, Canada and some other Commonwealth realms. The author of the tune is unknown and it may originate in plainchant, but an attribution to the composer John Bull has sometimes been made.
