Skippy the Bush Kangaroo is an Australian television series created by John McCallum, produced from 1966–1968, telling the adventures of a young boy and his intelligent pet kangaroo, and the various visitors to the fictional Waratah National Park in Duffys Forest, near Sydney, New South Wales. Ninety-one 30-minute episodes were made over the three seasons of production. At the time of first screening, Australian television was still in black and white, however, the show was filmed in colour on 16 mm film to increase its international marketability, especially in the United States and Canada, where it aired in syndication between 1969 and 1972. The Nine Network readily repeated the series several times after Australian television switched to colour transmission in 1975. The series was dubbed into Spanish in Mexico, where it is known as Skippy el canguro, and has been distributed to most Spanish-speaking countries, including Cuba and Spain, where it became very popular. The series crossed the Iron Curtain and was aired in Czechoslovakia and Soviet Union in the 1970s and 1980s, and is still being broadcast in Iran.
