Trinity Bay State High is a co-educational school with an enrolment in 2015 around 1650 students, across Year levels 7 to 12. The school draws from the surrounding “three M” suburbs of Manoora, Manunda and Mooroobool in addition to populations in surrounding mortgage belt suburbs. Trinity Bay SHS continues to grow with students attracted by the excellent programs offered at the school. The student population reflects the multicultural nature of the greater city of Cairns and supports just over 100 students in an Intensive English Language program. Approximately 30% of students identify themselves as being indigenous, the majority of these being Torres Strait Islander.
