Few records are available for this year, but it is known that Prospect, who had previously applied at least in 1911, 1912 and 1920, was at last accepted. Ironically, it was to stay just the one season before switching to the YMCA and then the North Adelaide District Association, and replaced another one-season resident in East Adelaide who foreshadowed Prospect’s move by leaving itself for the YMCA Association.
The exchange of East Adelaide for Prospect maintained the 8-team competition.
In the Semi Finals, University 10.13 beat Semaphore 8.7, and Prospect 13.11 beat Kingswood 11.12. Hence Prospect became the third club after Kingswood and Henley & Grange to play in the Final in its first year of entry into the Amateur League. However, University was too strong on the day and went on to win its fourth premiership, beating Prospect in the Final 9.10 to 7.11.
