On the 4th of October 1913 HMAS Australia led the new fleet through the heads of Sydney Harbour. HMAS Australia, an Indefatigable-class battle cruiser, was The Royal Australian Navy’s first flagship. A year later it was serving Australia in World War I. After distinguished service HMAS Australia was decommissioned and eventually scuttled off Sydney Heads on April 12 1924. This film records the last moments of that important piece of Australian Naval history.
