When the Sydney Roosters or Eastern Suburbs District Rugby League Football Club (ESDRLFC) first entered the New South Wales Rugby League (NSWRL) competition in 1908, the tricolours would become neighbours to fellow city counterpart, the South Sydney Rabbitohs, then the South Sydney District Rugby League Football Club (SSDRLFC). The original articles of association binding both the ESDRLFC and SSDRLFC with the NSWRL defined the territories of both clubs. Easts were formed to represent the local government areas of the City of Sydney, Darlinghurst, Paddington, Vaucluse, Woollahra, Waverley and Randwick. Meanwhile, Souths were to represent the local government areas of Redfern, Alexandria, Zetland, Waterloo, Mascot and Botany. Notwithstanding the local junior boundary changes referred to in this article, these articles of association have not changed, and as such the Roosters at senior level technically represent all of the local government areas as assigned in 1908, subsequent council mergers aside.
