Dubbo College was formed to bring together the three state schools in Dubbo. Dubbo High School officially opened on 8 July 1917 and the original building operated for 84 years before it was closed in June 2001. In 1962 the Minister for Education announced a second high school, Dubbo High South, to deal with increasing numbers of students.[2]
Dubbo High School published a quarterly school magazine called "the bindyite" which began in June 1918.[3]
The Astley Cup is an annual inter-school sports contest between Bathurst High Campus, Orange High School, and Dubbo College. The competition was founded in 1923 and continues to the present day.[4]
