She’s speaking up now as the anniversary of the alternative broadcaster’s eviction from the University of Queensland appropriately collides with protest efforts to save its former home.

Attempts to save the Schonell Theatre are expected to be at the forefront of celebrations as 4ZZZ goes back to its first home at UQ on Saturday.

Queensland Greens Senator and long-term 4ZZZ volunteer Andrew Bartlett will lead a panel discussion with the "Zedders" who were there at the Schonell Theatre when the conservative student union evicted 4ZZZ from its studios in 1988.

The 48-year-old theatre’s demolition has been mooted in the master plan for redeveloping the St Lucia campus but the university insists no final decision has been made.

Former UQ Union staff member Desley Agnoletto - better known to many as the co-creator of Pizza Caffe along with husband Pietro - had fond memories of her time at the theatre, from 1975 to 2006.

"I remember I went into work one morning and found everyone outside," she said.

"When the 4ZZZ team came into work, all the locks had been changed and they couldn't get in."

Ms Agnoletto was disappointed that the proposed rebuilding of the union building block area would also take the theatre and cafe with it.

"The Pizza Caffe was also so popular and busy, and the Schonell Theatre was Brisbane’s art house and theatre before Dendy cinemas came along and began showing their own films," she said.

"There wasn't anything in the campus where someone could eat and, with the theatre, we would have a movie and pizza deal for $25 back then.

"Everyone from all over Brisbane used to come to the university for our pizza."

Ms Agnoletto said the "Schonell Theatre family" would be heartbroken to see the theatre go.

"I’d hate to see the wrecking ball come in and knock it down. There's a lot of memories that have been made there and the Schonell has always been a lovely theatre," she said.

"It’s still being used even though they’ve closed the cinema."

A group of UQ staff and students are calling for the community to fight to keep the theatre as a historical building in the university.

Alternatively, students are pushing to keep some form of a theatre at the university amid fears there may not be a replacement if the Schonell Theatre is destroyed.

UQ Union president Georgia Millroy said community backlash stemmed from the master plan's lack of any replacement theatre.

"As Schonell has a rich history of independent performance and student-led political and creative expression, UQU thinks it is vital that any new theatre continues to be operated by students for students, through UQU," she said.

"UQU is appreciative that UQ has listened to the response from students and the community regarding the importance of the Schonell Theatre and keeping a creative space on campus."

Ms Millroy said many students had chosen to study at UQ mainly because the university had its own student-run theatre.

"Many law and arts students who use the space will be sad to see it go but if it has to go; we would like to preserve historical pieces from the Schonell Theatre to keep the memories alive," she said.

"I think a lot of former UQ students have a soft spot for Schonell as it has been such a hub of activity since it was built."

Many students would remember the 4ZZZ protests during the Joh era, watching a movie in the old theatre, or seeing a fantastic student-lead performance.

"There is a significant group of current students who value Schonell due to what it represents," she said.

"These include drama and performing arts students as well as those from the law and medicine faculty who utilise the theatre for the annual revue show."

A UQ spokeswoman said the university was considering feedback as it continued to engage with students around their current and future requirements.

"The university received 153 submissions during the 10-week public consultation period on its draft site development plan," she said.

"Many of these submissions sought assurances that a performance space would continue to be provided on campus if plans for a new student hub proceeded.

"The need for a new student hub was identified to meet the changing requirements of UQ’s students, and to provide them with world-leading education facilities so they can excel in the workplace of the future."

The spokeswoman did not respond to questions on whether the university had plans to save the theatre or whether a replacement theatre would be created.

"No final decision has been made on a proposed student hub," she said.

"The university is still in a consultation and feasibility phase. This will take some time, with a recommendation likely in the second half of 2019."

The event will be held at the St Lucia campus on Saturday from 4pm to 7pm.
