Dutton Park has been revealed as the site for Queensland's next high-rise school.

The Queensland government has been investigating several sites for a new inner-south high school to ease the enrolment pressure on Brisbane State High School.

The decision was based on the proximity to the city, connections with existing transport infrastructure and the nearby tertiary education partner, the University of Queensland.

Parents have had concerns about how Brisbane State High School, which cannot physically expand, would cope with hundreds of extra students due to the rapid increase in apartments in West End and South Brisbane.

The Dutton Park school is expected to open in 2021.
