[2] In the early 1920s the old boys of five of the Great Public Schools of New South Wales decided to establish a Sydney central business district base for their fellow alumni.
[3] Those involved in the development of this idea wanted to provide a clubhouse where men, who had recently left school and had undertaken business careers, could meet.
[4] The club opened in premises owned by the Fairfax newspaper family at a building that was later demolished for the development of Australia Square.
[6] Initially some facilities were shared but each member school managed a separate club room in its own style.
The original clubhouse was demolished in 1962 for the Australia Square development and the club transferred to a new building near Circular Quay.
