The loss and the controversy

On 19 November 1941, HMAS Sydney, a light cruiser of the Royal Australian Navy with an impressive record of war service, was lost following a battle with the German raider HSK Kormoran in the Indian Ocean off the Western Australian coast. The loss of the Sydney with its full war complement of 645 remains Australia’s worst naval disaster. The Kormoran was also sunk, but 317 of its crew of 397 were rescued. This fate of the Sydney remains one of Australia’s greatest wartime mysteries with not even the location of the wrecks established until 2008.

For twelve days the government maintained the strictest secrecy about the loss of the Sydney. When the Prime Minister made the first of two public announcements on 1 December 1941 he did little more than confirm rumours that the Sydney had been sunk. For the public the shock of the loss was accompanied by bewilderment that such a disaster could occur. A suspicion that information was being concealed was strengthened by the delay in making the official announcement, by the lack of any real explanation when the announcement did come, and by the secrecy which surrounded the official investigation of the disaster.

Little information was released until 1957, when the official history of the RAN in World War II was published (G Hermon Gill, The Royal Australian Navy 1939–42. Volumes 1 and 2. Official History of Australia in the War of 1939–45, Australian War Memorial, Canberra, 1957). Despite the history’s assertion that the story of the Sydney’s last action ‘was pieced together through exhaustive interrogation of Kormoran’s survivors’ and that ‘no room was left for doubt as to its accuracy’, its failure to answer important questions confirmed for some the suspicion of an official cover-up.

The controversy over the loss of the Sydney continued to trouble many Australians and in 1997 the Minister for Defence asked the Parliamentary Joint Committee on Foreign Affairs, Defence and Trade to inquire into the circumstances surrounding the loss of the vessel. The Committee, which was assisted by an historical adviser, received in excess 400 submissions, and took evidence at hearings held in most Australian capital cities. In its report, which was tabled in Parliament in June 2000, the Committee placed on the public record for the first time the findings of a major inquiry into the Sydney disaster. A copy of the report is available at www.aph.gov.au/house/committee/jfadt/sydney/reportinx.htm.

The records

A number of commentators have held the view that Australia's government archives must hold documents which will provide answers to the Sydney controversy. In response to the continuing interest in the subject the National Archives has undertaken a systematic and extensive search of its holdings and of related records still in the Department of Defence in order to identify all relevant records. The research guide The Sinking of HMAS Sydney: A Guide to Commonwealth Government Records, by Richard Summerrell, lists and describes all records identified by this search.

Commonwealth government records relating to the sinking of the Sydney are held by the Archives' offices in Melbourne, Canberra, Sydney and Perth, and by the Australian War Memorial and the Department of Defence in Canberra. The records include war diaries, signals, Central War Room operations records, naval and air track charts, War Cabinet and Advisory War Council papers, and interrogation and intelligence reports. A number of the key records are listed below.

No records of any formal investigation into the sinking at the time have been identified, although the following two references have been located:

• Advisory War Council minute 842 of 18 March 1942, summarises the findings of a Naval Court of Enquiry (see item A5954, 813/2). No other reference to this Enquiry, nor any records of such an enquiry have been found.
  
• A reference to a Naval Intelligence investigation conducted in January 1942 (see item MP1049/5, 2026/19/6). No other reference to the report of this investigation (nor the report itself) has been located.

A search of archives holdings in the United Kingdom in 2001, as recommended by the Parliamentary Joint Committee report, located a small parcel of papers relating to the crew of the Kormoran that had been forwarded from Australia to the British government during the war. These have been digitised and placed on the Department of Defence website at www.navy.gov.au/HMAS_SYDNEY_and_KORMORAN_DOCUMENTS.
