"Down Under" is a song recorded by Australian rock band Men at Work. It was originally self-released in 1980 as the B-side to their first local single, "Keypunch Operator", before the band signed a recording contract with Columbia Records. Both early songs were written by the group's co-founders, Colin Hay and Ron Strykert. The early version of "Down Under" has a slightly slower tempo and different arrangement from the later Columbia release. The best-known version was then released on Columbia in 1981 as the second single from Men at Work's debut studio album Business as Usual.
