Established in 1909, by the Anglican Archbishop of Melbourne, Henry Lowther Clarke, the school currently caters for approximately 1,100 students. The Early Learning Centre and primary school are co-educational, whilst the secondary school (Years 7–12) is for girls only.
Firbank is a member of the Australian Anglican Schools Network, the British Schools and Universities Foundation  and Girls Sport Victoria (GSV). Firbank has close ties with its brother school, Brighton Grammar School, a boys' school. Students of the two schools participate in a number of co-educational activities together such as music and drama.
Firbank Grammar School was established as a Christian, day and boarding school for girls in 1909, by the Anglican Archbishop of Melbourne, Henry Lowther Clarke who was left a legacy for educational purposes. The Archbishop purchased 'Gawsworth', a property which stretched between Outer and Middle Crescents, and named the school after his birthplace in Westmorland, England. He chose the motto, Vincit Qui Se Vincit ("She conquers who conquers herself") and gave the School his Archbishop crest.
Under the leadership of Maud Cameron, Firbank's first and longest serving Headmistress, enrolments grew and further land was purchased, including the 'Pen-y-bryn' estate and 'Atherstone' in Sandringham. Since its foundation, Firbank has maintained a strong connection with St Andrew's Anglican Church, Brighton where formal school services are held.
Firbank consists of three educational sections on two campuses: 'Sandringham House', a co-educational primary school in Sandringham; 'Turner House', a primary school for girls; and the Senior School catering for girls only in Years 7 to 12. The houses are Sheppard-Tyson, Aylwin-Cameron, Tonkin-Clarke and Hancock-Crowther.
Firbank has competed in rowing since 1992. It claims to have produced many nationally and internationally recognised swimmers. Firbank has lots of very special students when it comes to sports, and Firbank also has a program going every term called GSV Sports for Year 7-12, and lots of girls participate. There are two sports every term.
The Brighton campus was one of the sites for filming the 2005 television series We Can Be Heroes: Finding The Australian of the Year and, in 2007, two episodes of the television production Neighbours.
