History
The Distinguished Service Medal was established on 14 October 1914 as the third level decoration for gallantry in action by ratings of the Royal Navy, below the standard required for the Victoria Cross or the Conspicuous Gallantry Medal. It was the lower-deck counterpart of the Distinguished Service Cross, which recognised officers and warrant officers, and it rewarded bravery and resourcefulness on active service at sea. From 1916 bars could be authorised for further awards.
It was awarded to ratings up to and including chief petty officer, and its precedence placed it between the George Medal and the Military Medal once those awards existed. About 11,311 medals were awarded between 1914 and 1993, when the reform of the honours system opened the Distinguished Service Cross to all ranks and the Medal was discontinued. Like other reign-spanning awards it carries the effigy of the sovereign of the day. As an Imperial award it retains its place in the Australian Order of Wearing.
Design & ribbon
The medal

The ribbon is dark blue with two central white stripes, the naval colours distinguishing it from the crimson gallantry ribbons of the land services.

Order of wear
Imperial awards were the honours of Australia before the Australian honours system was established in 1975, and they retain their place in the Order of Wearing. They are worn after the Australian honours of their kind and among the Imperial awards in the order set by the Australian Order of Wearing, which follows the British order of precedence.
