The Schneider ES-52 Kookaburra is an Australian two-seat training sailplane of the 1950s and 1960s. It was designed by Edmund Schneider, the designer of the Grunau Baby, who had emigrated to Adelaide, South Australia following the end of the Second World War.[1]

The Kookaburra is a cantilever high-winged monoplane of wooden construction, with staggered side-by-side seating under a perspex canopy. The first example flew on 20 June 1954. It was available in both short and long wingspan versions and was widely used by Australian gliding clubs in the 1960s.[1]
