ST Johns Park High School is applying to the Department of Education and Communities to sell unused land on the school grounds.
The land to be sold is located in the north-eastern corner of the school, bounded by Greenfield Road and Mistral Street.
"In accordance with Department of Education and Communities guidelines, a public meeting will be held, at which local community members can express their views about, and their objections to, the land sale," said school principal Sue French in a letter to the community.
The meeting will be held in the school's common room from 5.30pm on Wednesday, March 26.
"The Department of Education and Communities is solely responsible for the sale of the land," Mrs French went on to say in the letter.
"Discussion about any of the processes involved in the land sale will not be occurring at the public meeting.
"The sale of the land will enable the school to fund a number of large scale projects that will significantly improve the teaching and learning opportunities provided for the students of St Johns Park High School.
"I look forward to meeting you at the school to discuss the sale of the land and the opportunities it will provide for the students of our school."
St Johns Park High School is located in Mimosa Road, Greenfield Park.
