The Australian Defence Medal is an award established to recognize the service of members of the Australian Defence Force (ADF) who have completed a minimum of four years of service. It acknowledges both regular and reserve personnel, as well as those who have served in the ADF's operational and non-operational roles. The medal features a design that reflects Australia's military heritage and is awarded without the need for a specific act of bravery or service in combat. Eligibility for the medal includes service in the Royal Australian Navy, Australian Army, or Royal Australian Air Force. The medal is a symbol of commitment and dedication to the nation, promoting pride among service members and their families. Recipients may wear the medal on formal occasions, signifying their contribution to Australia's defence efforts.
