Brisbane's first vertical high school will almost certainly be built in Fortitude Valley by 2020 on the site of the former state school on Brooke Street, Queensland Education Minister Kate Jones says.
Ms Jones said the Valley would likely be home to the state's first high-rise school, with the second possibly set for Brisbane State High School's catchment area, which includes West End, South Brisbane, South Bank, Highgate Hill and parts of Dutton Park.
"There is an expectation that we will be looking at different models of development on that small Valley site," Ms Jones said.
"So yes, that gives us an opportunity to look at a vertical school on that site."
Ms Jones said a site for the southside vertical high school had still not been decided.
Last month, Education Queensland began investigating a "vertical high schools" policy and a recent Queensland government tender asked for experienced school principals to investigate the issue.
The tender for Brisbane Inner City School Strategy closed last month.
"The purpose of this Expression of Interest is to establish a shortlist of principal consultants who can demonstrate recent and relevant experience in, and understanding of, the issues associated with planning and designing inner-city vertical schools," the tender said.
Education planners have already visited Melbourne's 10-storey Haileybury campus, which started the year with 237 students from Year 1 to 9.
Fairfax Media outlined this Melbourne school in February as an option in space-restricted inner-city Brisbane suburbs earlier this year.
That campus was built in a renovated call centre in inner-city Melbourne and opened this year after Victorian education authorities failed to plan for an increase in young families living in inner-city Melbourne.
Successive Queensland governments have failed to increase the scope of inner-city schools as new apartments were constructed and families with school-aged children crammed places at inner-city schools.
The biggest impact was on Brisbane State High School, which now has 3190 enrolled students and the crammed West End State School.
Subsequently, in June, Queensland Premier Annastacia Palasazczuk, Deputy Premier Jackie Trad and Ms Jones announced two new high schools for inner-city Brisbane at a cost of $500 million.
Ms Jones said a trip to Melbourne to see where the city's Monash University had science education links with nearby high schools encouraged her to ask Queensland University of Technology and the University of Queensland to partner the new high schools in Fortitude Valley and somewhere between South Brisbane and Dutton Park.
"They were both pretty excited to be involved," she said.
Ms Jones said QUT was holding a planning day in November, to be run by Department of Education regional director Mark Campling, to develop concepts for the vertical school on the old Fortitude Valley state school site.
"With the UQ concept, we still haven't got a site just yet," she said.
However Ms Jones confirmed it would be within Brisbane State High School's catchment area and Mr Campling had begun work with the BSHS community.
Ms Jones quashed a rumour the original Brisbane State High School would become a "catchment-only" school and the new high school in the catchment would cater for more than 1000 BSHS students who received places on academic, sporting or cultural merit.
"That is absolutely not true," Ms Jones said.
"No, No, No. Not true."
Ms Jones has previously said the new schools at Fortitude Valley and in the inner-south would be built with a capacity of 1200 to 1500 each.
Ms Jones said a third site in Vulture Street near West End State School, now owned by the Queensland Police Service, had been set aside for the state school expansion.
