The ARLC South Australia Ltd known as NRL South Australia, is the official governing body for the game of rugby league in SA. In 2015 the name NRL South Australia (NRL SA) replaced the name previously used, the South Australian Rugby League (or SARL). The change occurred at the same time that governance of Rugby League in South Australia moved from a member based Incorporated Association to that of a company limited by guarantee under the Australian Rugby League Commission.
A non-for-profit organisation, the NRL SA is affiliated with the National Rugby League (NRL) and is governed by and receives funding from the Australian Rugby League Commission (ARLC). The NRL SA is also supported by the Office of Recreation and Sport and Sports SA.
