Established in 1908 as the Secondary Schools Sports Association,[1] inter-school competition commenced in 1909 in the sports of Swimming, Tennis and Basket Ball.

Competition is offered to, and organised for, girls from Years 7 to 12.

There is some evidence to suggest that Moreton Bay College may also have participated in sporting competitions in the early years.

[1] The association had been initiated by Constance Elizabeth Harker, co-Principal of Somerville House,[2] and its aim was to "promote a friendly spirit between schools and at the same time deepen and strengthen the loyalty of individual girls to their own school".

[1] Ipswich Girls' Grammar School and St Hilda's School joined the Association in 1911, followed by the Brisbane State High School in 1921, St Aidan's Anglican Girls' School in 1939, Clayfield College in 1941, Moreton Bay College in 1945, and St Peters Lutheran College in 1946.
