The WW2 Australian Navy Flag, measuring approximately 34 inches by 17 inches, represents the official ensign used by the Royal Australian Navy during the Second World War. This flag features the Union Jack in the canton, with a blue field displaying the six-pointed Commonwealth Star and the constellation of the Southern Cross in white. Flags of this type were flown on Australian naval vessels between 1939 and 1945, symbolizing the nation’s commitment as part of the Allied naval forces. The construction typically involves durable cotton or wool bunting with stitched or appliqued details, suitable for withstanding maritime conditions. The proportion and layout conform to naval regulations of the era. Such flags hold historical significance as tangible artifacts from Australia’s naval operations during WWII, and are sought by historians and collectors interested in military maritime history. This example offers insight into both national heritage and naval standards in the mid-twentieth century.
