The Conspicuous Service Medal was introduced in 1989 to recognise meritorious achievement or devotion to duty in non-warlike situations. The medal is nickel-silver with the obverse having a central device of the Southern Cross surrounded by a laurel wreath. The reverse has a horizontal panel for recipient details over a design of fluted rays.
The ribbon has alternating narrow diagonal stripes of bush green and sandy gold.
A further award is denoted by a nickel-silver bar with a superimposed central replica of the Medal flanked by laurel leaves.
When the ribbon is worn alone, the award of a bar is indicated by the addition of a ribbon bar emblem in the form of the Medal. Recipients of the medal are entitled to the postnominal letters ‘CSM’. Recipients of a bar add ‘and Bar’ to the postnominal.
