Searching for answers online and this came up!
Probably not yours as this college was in Australia, but what a coincidence on the address and dates! (Sorry Milly just noticed you picked that up too!)

Korowa Anglican Girls' School was established in 1890, first in two houses in
Valetta Street, Malvern and then in an old house in Pine Grove. In 1900 the school moved again, this time to a two storey house in Wattletree Road. The school was registered as "School No.5" in 1906.[11]
