In June 1913 it was decided that Kogarah would be a suitable site for a new high school. On 31 October 1914, the land occupied by the cottage ‘Harrow Villa’ was purchased from its owner. This cottage with portable buildings added became the temporary St George Girls High School. St George Girls High School officially opened in February 1916 with 143 students and nine teachers.

Organisations
The School has four school organisations which provide support to the school:
P & C Association - St George Girls High School Parents & Citizen' Association takes an active interest in the welfare and education of students. When possible, they have a guest speaker.
St Georgians - The St Georgians is the association for ex-students of the school to meet regularly.
Prefects - At St George Girls High School, there are 15 School Prefects, of them are two Vice Captains and one School Captain. These students are nominated and voted by their fellow Year 12 peers and lead in the planning events for their cohort and the wider school community.
Student Representative Council - St George Girls High School has an active Student Representative Council. Students from each year elect representatives from their class to represent them at SRC meetings. The SRC consists of four Year 11 students selected by the students of the school. In the past, the SRC has participated in charities such as Daffodil Day, Jeans for Genes day and Pink Ribbon day as well as fundraising activities such as the Walkathon, Gelato Days and Mufti Days. Money raised from school fundraising activities is used for improvements within the school. Recent SRC projects include planting of trees for shade, purchasing teaching resources in the school and providing additional seating arrangements around the school quadrangles.
Associated schools
Although St George Girls High School is an all-girls school, Sydney Technical High School is often referred to as their male counterpart. Being the 'Brother School' of St George Girls High School, Sydney Technical High School often engages in joint SRC fundraising activities. Examples of these include SRC school dances, the St George vs. Sydney Tech netball game during SRC week, as well as P&C meetings. Each schools' ISCF Group regularly join to become Lightly Salted.
