There are many graves commemorated by the Commonwealth War Graves Commission and maintained by the Office of Australian War Graves in locations spread throughout the Eastern Suburbs Memorial Park. The Botany General Cemetery section contains 157 burials: five Commonwealth burials of the First World War and 150 burials of the Second World War. There are also two Dutch Second World War burials maintained on behalf of the Dutch War Cemetery Organisation (Oorlogsgravenstichting). The Crematorium section contains 31 burials of the Second World War, comprising 30 Australian and one British burial. These include five Royal Australian Air Force servicemen killed in an Avro Anson crash at RAAF Richmond in December 1939. The remains of four Japanese sailors killed and recovered from the May 1942 Attack on Sydney Harbour were cremated and stored in the columbarium of the Crematorium until they were able to be returned to Japan by the returning Japanese Minister, Tatsuo Kawai, in August 1942.
