In 1910 the Adelaide University Sports Association thought the case for admission to SAFA would be strengthened if the University had a team playing successfully in regular competition. It was felt that this could be achieved by forming a purely amateur league with other clubs not already in an association. By late 1910 Glenferrie, Marlborough and St. Bartholomew clubs had agreed to join with University to form the new association based on amateur principles. By 1911, as preparations were in hand for the inaugural season, the four clubs had become five with the inclusion of St. Francis Xavier. The clubs also had agreed to admit late applicant Semaphore Central for the 1912 season.
