A State of Origin competition is a type of sporting event between players representing their state or territory. State of Origin began in Australian rules football on 8 October 1977 between Western Australia (WA) and Victoria, at Subiaco Oval in Perth, the initial brainchild of Leon Larkin. The selection criteria for Australian football have varied, but they are generally applied to players who have played most of their juniors games in a particular state or territory, hence the name "State of Origin". In Rugby League the criteria are different, where players are selected for where they either first played senior Rugby League or where they played in the majority of senior competitions. The annual Rugby League State of Origin series is one of Australia's most popular sporting events. The name is also used in Australia for small sporting events which generally involve domestic representative teams.
