It is awarded to personnel who complete 15 years of Regular or Reserve service, or combinations thereof, on or after 14 February 1975. Additional service clasps, each indicating a further 5 years after the initial 15 year qualifying service, are issued. The first four clasps to the medal are indicated by rosettes on the ribbon. These are replaced by a single silver Federation Star for the fifth clasp. Additional Federation Star emblems are added for subsequent clasps.[3]
Description
According to the Australian Department of Defence, the medal is described as:[3]
The reverse has a central horizontal panel surrounded by the inscription "For Service in the Australian Defence Force" in capital letters.
The ribbon has a central panel of seven alternating blue and gold stripes flanked by blue stripes gold edges. The colours and design reflect those of the replaced medals.
The clasp is a cupronickel bar with the Royal Cypher flanked by sprigs of wattle in the centre. When the ribbon is worn alone a clasp is indicated by the addition of a cupro-nickel round rosette or a silver miniature Federation Star.
While the Australian Defence Medal is sometimes classified as a "long service medal", it is intended to recognise all those who completed an obligation to serve their country (whether voluntarily or conscripted), and is not awarded for "long service" per se.[citation needed]
