The boxing kangaroo is a national symbol of Australia, frequently seen in pop culture. The symbol is often displayed prominently by Australian spectators at sporting events, such as at cricket, tennis, basketball and football matches, and at the Commonwealth and Olympic Games. The flag is also highly associated with its namesake national rugby league team – the Kangaroos. A distinctive flag featuring the symbol has since been considered Australia's sporting flag. History The idea of a boxing kangaroo originates from the animal's defensive behaviour, in which it will use its smaller forelegs (its arms) to hold an attacker in place while using the claws on its larger hind legs to try to kick, slash or disembowel them. This stance gives the impression that the kangaroo appears to be boxing with its attacker. The image of the boxing kangaroo has been known since at least 1891, when a cartoon titled "Jack, the fighting Kangaroo with Professor Lendermann" appeared in the magazine Melbourne Punch. In the late 19th century, outback travelling shows featured kangaroos wearing boxing gloves fighting against men. Das Boxende Känguruh, an 1895 German silent film directed by Max Skladanowsky, and an English silent film, The Boxing Kangaroo, produced by Birt Acres in 1896 also both featured kangaroos boxing against men, while the American animated shorts The Boxing Kangaroo (1920), Mickey's Kangaroo (1935) and Pop 'Im Pop! (1949) helped establish the concept of a boxing kangaroo as a popular culture cliché.. The 1978 Hollywood movie Matilda, which starred Elliott Gould and Robert Mitchum, featured a boxing kangaroo that was exploited for prize fighting. During World War II boxing kangaroos were stencilled on Australian fighter aircraft of No. 21 Squadron RAAF based in Singapore and Malaya to differentiate their aircraft from British planes. The practice soon spread to other units, as well as onto ships in the Royal Australian Navy. In 1983 the boxing kangaroo received national and international prominence when it served as the symbol for the successful Australian challenge for the America's Cup, where the boxing kangaroo flag, a red-gloved golden kangaroo on a green background, was flown from the yacht Australia II. Alan Bond (owner of the Australia II yacht) owned the image and licensed it for mass production. The image was later bought by the Australian Olympic Committee, and is used as a mascot to represent the Australian Olympic team and to promote sport and fair play
