 A third wing was added to the "permanent" buildings and enrolment continued to grow to over 2000 students in the latter half of the decade.Enrolment eventually declined with the maturing population of the city and the establishment of another high school in Elizabeth West nearer the developing suburbs that had extended northwards into Munno Para.In 1988, amalgamation with Playford High School formed Elizabeth City High School, and the schools were combined at the Philip Highway site.
