History
The Australian Active Service Medal was established on 13 September 1988 by Letters Patent, gazetted that November, to recognise the service of Australian Defence Force members and certain other persons in prescribed warlike operations on or after 14 February 1975. It was created as the warlike counterpart to the Australian Service Medal, as the young Australian honours system took over campaign recognition from the Imperial system.
Because the medal is always awarded with a clasp naming the prescribed operation, its clasps trace three decades of deployments: the Gulf War of 1991, Somalia and Rwanda, the Balkans, the East Timor intervention, and the International Coalition Against Terrorism clasp for the Afghanistan era. Since the Australian Operational Service Medal was established on 22 May 2012, new operations have been recognised by that medal, while operations already declared for the Active Service Medal continued under it, with Operation Slipper service running to 31 December 2014 and Operation Palate II to March 2017.
Design & ribbon
The medal
The Australian Active Service Medal is a nickel-silver medal ensigned with the Crown of St Edward. The obverse shows a Federation Star flanked by a wreath of mimosa. The reverse bears a stylised laurel wreath surrounding the inscription FOR ACTIVE SERVICE. A nickel-silver clasp carrying the name of the prescribed operation is presented with the medal.
The ribbon

A central red stripe for the danger of warlike operations, set within bands of Australian green and gold.
The ribbon has a central red stripe symbolising the danger of warlike operations. It is flanked by stripes of silver-green, which are in turn flanked by stripes of light green, gold, dark green and brown, the colours being variations of the Australian green and gold.

The medal is always awarded with a clasp naming the theatre or action for which the award is made. A further award of the medal in another area is recognised by an additional clasp, worn above previously awarded clasps in order of date of receipt. The following clasps have been issued.

- For members allotted or assigned to an operation, the qualifying period is commonly one day of service or one sortie, while visitors and members on temporary duty commonly require thirty days;
- Several clasps, including Balkans, Cambodia, Namibia and Rwanda, were upgraded from the Australian Service Medal after the service was reclassified as warlike;
- There is no post-nominal for the medal.

Frequently asked questions
What is the difference between the Active Service Medal and the Service Medal?
The Active Service Medal recognises warlike service, while the Australian Service Medal recognises non-warlike and peacekeeping service. Some operations were upgraded from one to the other when the nature of the service was reassessed.
Why is the medal always worn with a clasp?
The clasp names the prescribed operation for which the award is made. Further service in another prescribed operation is recognised by an additional clasp, worn above earlier clasps in order of date of receipt.
Is the Australian Active Service Medal still awarded?
Applications are still processed for service within operations declared before 2012. Operations declared after 22 May 2012 are recognised by the Australian Operational Service Medal instead.
Which clasp covers Afghanistan service?
The clasp ICAT covers Operation Slipper service to 31 December 2014 and Operations Palate and Palate II to 2017. The same deployments are also recognised by the Afghanistan Medal, and service from 2015 falls under the Operational Service Medal, Greater Middle East Operation.
How much service is needed to qualify?
The qualifying period is set by the declaration for each operation. It is commonly one day of service or one sortie for members allotted or assigned to the operation, and thirty days for visitors or members on temporary duty.
Does it carry a post-nominal?
No.
