Alongside their own junior teams, the Rams have a sister program ran by the Macarthur Football Association to help source players and maintain a football pathway. These teams operate under the name 'Macarthur Football Association', commonly referred to as 'MFA' or 'Macarthur FA'. MFA teams also compete in SAP, but youth teams (U13s, U14s, U15s, U16s and U18s) compete in the Football NSW administered Association Youth League (AYL), located fourth in the Football NSW boys youth system, one tier below Rams. The AYL consists of teams representing their respective regional association, and cannot be promoted or relegated.
