 After the war, when Australia's military was reorganised the 43rd Battalion was reformed once again as an amalgamated unit known as the 43rd/48th Battalion, which remained in existence until 1960 when it was subsumed into the Royal South Australia Regiment (RSAR), following a reorganisation that saw the creation of six multi-battalion state-based regiments within the Citizen Military Forces.In 1961, the battalion was entrusted with the 14 battle honours awarded to the 2/43rd Battalion for their involvement in the fighting in North Africa and the South-West Pacific during the Second World War.Although it currently no longer exists, for a period after 1966, following the reintroduction of national service, the 43rd Battalion was re-raised within the RSAR, as a remote area battalion within the Citizens Military Force, offering special conditions of service for soldiers who had elected to serve in the CMF rather than the Regular Army, but who could not meet their training requirements through normal attendance due to their occupation or place of residence.
