Carols by Candlelight is an Australian Christmas tradition that originated in southeastern Australia in the 19th century and was popularised in Melbourne in the 1930s. The tradition has since spread around the world. It involves people gathering, usually outdoors in a park, to sing carols by candlelight, accompanied by a band. Today, the largest such event is held annually at the Sidney Myer Music Bowl in Melbourne's King's Domain Gardens on Christmas Eve, since 1938, 71 years.
