Replica Medals Defence Force Service Medal and Australian Defence Medal. The Defence Force Service Medal was awarded to full-time service personnel for 15 years diligent service in the Australian Defence Force. The medal is one of three Defence Force Service Awards that recognised long-service. History The Defence Force Service Medal is part of a long tradition of rewarding long service and good conduct by a member of a nation's armed forces. Britain has the most developed system with the oldest Imperial award for naval long service introduced by King William IV in 1831. The Defence Force Service Awards were established on 20 April 1982 by Letters Patent, providing distinctive Australian military long service honours. Between 1975 and 1982, defence force long service was recognised by the award of the National Medal, which is now primarily a civilian award. Prior to this, Australians in the defence and reserve forces were eligible for Imperial awards. Along with the Reserve Force Decoration and the Reserve Force Medal , the Defence Force Service Medal was replaced by the Defence Long Service Medal in 1998. Members already holding this medal may continue to earn clasps to the medal even though the medal itself is no longer awarded.
