Glenunga International High School

The school was established in 1903 from the defunct Adelaide Agricultural School (founded 1897 with Andrew Ferguson as headmaster) as the Preparatory School for the South Australian School of Mines and Industries. It was renamed the Junior Technical School in 1914 and then Adelaide Technical High School in 1918. a development which was instigated to help save the school from closure due to dwindling student numbers. With enrolments rising, GIHS has subsequently attracted substantial government funding and construction projects, most notably the technology and science wing extensions, a new administration block, and a performing arts centre; since 2005 there have been various additional changes to the facilities, such as extra rooms. In 2013, development began for a new $10 million building to accommodate the growing number of students. This new building was accompanied by the renovation of the Music, Sciences and Art departments, as well as a new library. The development upgrades were completed in 2014. In 2020, the construction for new buildings including technology facilities, science labs and classrooms began. The total cost of the new plan is roughly $32 million. The construction was completed at the start of 2022 for the introduction of year 7s into the school, which fully opened to students and staff in mid-Term 1. In 2025 a series of email threats were made to the principal, Wendy Johnson. Such threats caused a temporary rise in security surrounding the school and prompted police investigation. ==Student life==

These include special-interest clubs, a variety of community service organisations, as well as various sporting teams. Glenunga has numerous student-led clubs, which include the crocheting, chess, K-Pop, and philosophy clubs, amongst others. Glenunga International High School has an extensive student leadership model, which gives any student the opportunity to make change within the school community.
