The school is connected to many other organizations and networks within the education community and beyond. Some examples include:
We are supported by The Centennial Parkland Trust in the care and assessment of the trees on the site and we are fortunate to have the assistance of the arborist to provide expert advice about ideal plantings. Many school activities take place within the precinct of The Centennial Parklands and the school provides reciprocal support when needed, such as students helping at the Open Days which occur annually.
Our neighbouring school, Sydney Boys High, is a highly significant partner, supporting social networks amongst the students with events such as the Junior School Dance and the Annual Trivia night for the seniors. Students work together in fund raising initiatives for significant charities such as The Black Dog Institute, Red Cross and Refugee Week activities. Combined performing arts opportunities such as choir and orchestra are growing in strength.Partnerships with the UNSW and The University of Sydney support teacher training through the placement of professional experience students as well as professional dialogue. Sydney Girls High has provided advice and feedback relevant to the teaching practice sessions conducted by the universities and continues to actively participate in the teacher training in -school programs. The education faculties from both universities generously provide academic and research insights to assist the professional learning program for teachers at SGHS.
