The school was opened in 1933 as "Griffith Intermediate High School" at the cost of A£15,000, with the foundation of the main building laid by the Minister for Education, David Drummond, on 8 March 1933.[1][2] The school was upgraded to a fully comprehensive high school in July 1939.[3]
The school's badge consists of a green shield with the school's abbreviation "GHS" inside in gold, set above a gold scroll containing the motto. The motto, Postera crescam laude ("Later I shall grow by praise" or, more freely, "We shall grow in the esteem of future generations") is from a line in Horace's Odes: "ego postera crescam laude recens". It is also the motto of the University of Melbourne.
