SLSNSW is both a membership-based organisation built on a history of volunteerism encompassing a multitude of diverse and complex activities and an evolving entity responding to operational, economic and public factors. It is governed by the SLSNSW Board of Directors (SLSNSW Board), with significant input from the SLSNSW State Council and various Board Standing Committees. Through direction and oversight from the Board, the SLSNSW CEO manages SLSNSW. Different focuses and scopes of responsibilities are required from each group within SLSNSW to ensure a dynamic, contemporary and success-driven organisation.

The SLSNSW Constitution identifies various SLS entities and committees with or without voting rights to provide advice and direction as they represent the SLS membership in NSW.
