Girls continued to be educated in the school on Spring Street, renamed as Melbourne Girls' High School, until the building was condemned in 1930. The school was housed in the then-vacant Government House until 1933, when they moved to State School No. 1689 in King Street. In 1934, with the help of a donation from Macpherson Robertson, a new building was constructed the north-east corner of Albert Park Reserve. The school opened as the Mac.Robertson Girls' High School on 7 November 1934. The school was used as U.S Army Headquarters in 1942 and later by the R.A.A.F. The students took their classes at Brighton Road State School, Camberwell East Girls' School, and University High School during this period.
