Blackburn South was also home to several small primary schools, four of which were amalgamated into Orchard Grove Primary School in 1991. These were Blackburn South (demolished to build housing), Killoura (now the Blackburn English Language School), Mirrabooka (the site that Orchard Grove Primary now sits) and Warrawong (demolished to build housing, although the art room still stands and is now the Eley Park Community Association Warrawong Annex). Blackburn East Primary School, which was not part of the initial amalgamation, closed in 1993.
