The Returned Services League of Australia (RSL) was founded in 1916 to ensure a unified approach to address the lack of organised repatriation facilities and medical services available to those returning from service in the Great War.  This included looking out for the families of those comrades who did not return and arose out of discussions at a meeting in June 1916 of the Returned Soldiers Associations from QLD, NSW, SA and Victoria.

Harbord Diggers sub-Branch has been a proud and active member of the RSL since 1930's.
