[7] In the early 1960s, with astute signings and financial backing from the Greek community, Hellenic assembled a team that was by far the most successful club in the Brisbane competition.
[9] The match between Hellenic and Prague to decide the Australian Soccer Club Championship (a precursor of the Australia Cup established the following year) was played as a charity event and occurred at the Sydney Sports Ground on 19 April 1961.
In addition, Hellenic's style of play was described as giving Prague "a soccer lesson in passing and team combination from the start".
When these club joined the NSL St George-Souths took advantage of their absence to win another premiership, taking out the 1977 Brisbane Division One title on superior goal average after finishing level on points with Southside Eagles.
[16] After finishing as Division 1 runners-up to Southside Eagles in 1978, St George-Souths qualified for the 1979 NSL Cup, but were again knocked out by Brisbane City in the first round.
After finishing two seasons mid-table, St George-Souths withdrew from the league due to financial difficulties and merged with Olympic FC in 1982.
