 No. 87 Operational Base Unit (No. 87 OBU) was formed with No. 4 SFTS staff on 1 June 1945 to administer Geraldton's facilities and maintain its aircraft following the flying school's disbandment. On 20 May 1946, No. 87 OBU was disbanded and re-formed as Care and Maintenance Unit (CMU) Geraldton. CMU Geraldton was one of many such units that the RAAF raised for the storage and maintenance of surplus aircraft prior to their disposal after the war. It was disbanded on 5 September 1947. Most of the buildings constructed for the RAAF during the war were auctioned and removed around the same time.
