The WA Correspondence School moved to the Thomas Street School on the corner of Roberts Road and Thomas Street in Subiaco near their previous site which had been damaged by fire and adjacent to Perth Modern School. WACS also made use of some of the rooms at the former East Perth Primary School until it was demolished.

ISMS had used empty classrooms at the Thomas Street School, however in 1980 its teachers moved to Graylands Teachers' College, Mimosa Avenue, Mount Claremont.
