All three medals were replaced with effect 20 April 1999 with a single medal, the Defence Long Service Medal,[3][4][5] which is now awarded to all permanent and reserve members irrespective of rank.[6]
Additional service clasps are issued for each further 5 years after the initial 15 year qualifying service period. On the ribbon, a rosette indicates the award of each clasp, although a small Federation Star indicates the fifth and subsequent clasps. With the introduction of the Defence Long Service Medal, the DFSM is now a closed award with only clasps to existing awards continuing to be issued.
The reverse is inscribed "For Efficient Service in the Permanent Forces" in capital letters around the circumference.
The ribbon has three equal stripes of gold and azure-blue edged with azure-blue. The colours were the national colours of Australia at the time of introduction.
The clasp is a cupro-nickel 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 not awarded for "long service" per se, 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).[citation needed]
