In Australia we have a number of choirs around the country whose purpose is to turn up to sing protest songs at rallies, marches & various community events. These include The Solidarity Choir, the Sydney Trade Union Choir, the Illawarra Trade union choir, the People's Chorus (just in NSW) & more.

The Solidarity Choir was the first of these choirs, formed in 1987, when Oliver Tambo, then President of the African National Congress, came to Sydney on a speaking tour. Sydney-based anti-apartheid activists brought together ANC members and Australian supporters to learn the anthem Nkosi Sikelel' iAfrica and other freedom songs to sing at a public meeting at Sydney Town Hall on 30 March. It was so much fun that the members decided to continue singing together. And so the choir was born!

The Solidarity choir does about 40 gigs a year, at rallies, fund-raisers for a wide range of community groups and solidarity movements, and folk festivals. Some of performance highlights over the years have been:
