[1][2][3] A number of current and former and League of Ireland clubs have played in the AUL at one time of another.

After completing their ban, Shelbourne spent the 1935–36 season playing in the AUL before rejoining the League of Ireland in 1936–37.

[6] Bray Wanderers played in the AUL between 1943–44 and 1954–55 before joining the Leinster Senior League.

In more recent seasons Frankfort, who were among the founding members of the League of Ireland, also played in the AUL.

[citation needed] A promotion and relegation system operates within the AUL structure itself.
