The Distinguished Service Medal was introduced in 1991 and is awarded for distinguished leadership in action.
The medal is nickel-silver with a Federation Star on a circle of flames on the obverse. The reverse has a panel for recipient detail over a design of fluted rays of varying lengths.
The ribbon has alternating stripes of silver-blue and ochre-red.
A further award is denoted by a nickel- silver bar with the Federation Star on a horizontal row of flames. When the ribbon is worn alone, the award of a bar is indicated by a ribbon bar emblem in the form of a Federation Star on a nickel-silver disc.
Recipients of the medal are entitled to the postnominal letters ‘DSM’. Recipients of a bar add ‘and Bar’ to the postnominal.
The nomination procedure is detailed in Chapter 8 Annex A of the Defence Honours and Awards Manual.
