The Interstate Rugby League Series refers to Australian Rugby league matches played between the New South Wales rugby league team, colloquially known as the 'Blues', and the Queensland rugby league team, known as the 'Maroons', between 1908 and 1981. The Interstate Series concept was based upon the state of residency of the player, however, due to NSW disinterest from 1962 to 1981, the State of Origin concept was initiated in 1980, and after two successful years with single matches, the superior origin concept became a three game series and the Interstate Series was scrapped in 1982.
