Australia
Active Service Medal 1975-
The Australian Active Service Medal (AASM) was introduced in 1988 to recognise service in prescribed warlike operations since 14 February 1975.

The Medal
The AASM is a nickel-silver medal. The obverse has a Federation Star within a wreath of mimosa. On the reverse a laurel wreath surrounds the inscription 'FOR ACTIVE SERVICE'.

The Ribbon
The AASM ribbon colours are primarily variations of the Australian colours of green and gold with a central red stripe symbolising the dangers faced in warlike situations.

Clasps
A clasp with the name of the theatre or action for which the award is made is presented with the medal.

A further award of the AASM in another area is recognised by the issue of an additional clasp. Additional clasps are worn above previously awarded clasps, in order of date of receipt.
