In 1914 the Parish of Sacred Heart, West St Kilda, purchased the site where the school and church now stand for £1439 and raised the funds to build the first two brick classrooms on the site.
On Sunday 28th April 1918, His Grace the Most Reverend Dr Daniel Mannix, the Archbishop of Melbourne, blessed and opened the Church-School which was run under the guidance of the Presentation Sisters with Mother Anthony Patterson as the first principal.
Additional funds raised by parishioners led to the construction of two more classrooms in 1923 and the purchase of more land for a playground.
