The Fort Street Foundation was formed in 1998 as the brainchild of a group of 1949 Fortians Fortians who were returning to the School for their 50th year anniversary.. It is a registered charity and supports the school financially for initiatives including the development of buildings and facilities. The Foundation runs three funds: the Building Fund, the Library Fund (both tax deductible) and the Education Fund.
They saw the need to establish a way to raise funds for the school but as a separate entity. Then, as now, the focus was to support the school by raising money for a wide range of projects including the development and refurbishment of facilities, bursaries and student support. The Foundation is governed by a Board consisting of Fortian alumni and representatives of the school community.
