Current member schools

There have been critics of the GPS competition of Brisbane State High's membership to the GPS Competition, primarily because it is the only Public School in the GPS competition.

The term "Public Schools" in the GPS acronym encompasses all public education including the Grammar Schools who are indeed themselves Public Schools. (Grammar Schools Act, 1860)
