Senior grade premiership success finally arrived after a finals series in 1937 in the Lower North competition, when Salisbury defeated Virginia in the grand final.
During WW2 there was of course little activity and any matches played were organized purely on an ad hoc basis. The Club remained active during the war years with the minute book recording committee meetings during the early 1940s.
In 1949 Salisbury returned to the newly named Gawler & District Football League and remained there until 1960. During this period premierships were won in 1956 and 1957 (both against old nemesis Gawler South, who by this time had changed it’s name to South Gawler). In 1956 the Club adopted the Collingwood strip and became known as the “magpies” which it retains to this day.
Also in these post war years an emphasis was placed on junior football, and as a result the Salisbury Junior Football Club was established. Pioneering this development through the 1950/60s were Club administrators A.J.(Bert) Guerin and Dudley Magor, both of whom have perpetual trophies awarded annually at the Club to recognize outstanding potential in junior players. A.J.Guerin was also on the foundation Committee for the Central District Football Club that was established in 1959.
In 1961 the Club affiliated with the newly formed Central Districts Football Association (C.D.F.A.) thus ending its long association with the Gawler League. Other founding clubs included Salisbury North, Elizabeth, Two Wells-Virginia, Elizabeth North and Central District. This League facilitated junior grades and Salisbury consistently fielded all grades to ensure a secure future with junior development.
Premierships in this new League included 4 consecutive from 1968-1971. Club legend Barry Pilgrim coached these premierships and also won five C.D.F.A. Best and Fairest Association medals. He in fact could have won six, being pipped one year by his brother-in-law Graham Thomas in 1970.
In 1980 the Club celebrated its centenary, and the A grade reached the grand final but was unsuccessful in its attempt to win this significant premiership.
During the 1980s the C.D.F.A. was re-named to become the Northern Metropolitan Football League (N.M.F.L.). The 1980s was another successful decade with premierships in 1984,1986 and 1988.
