Caboolture State School opened in present-day Morayfield on 4 August 1873. In 1890, it was renamed Caboolture South State School. In 1908, it was renamed Morayfield State School. The original school building is still on the site and is heritage-listed. (This school should not be confused with the current Caboolture State School in Caboolture when originally opened in 1889 and was then known as Caboolture North State School).
