The Australian Operational Service Medal – Border Protection. The AOSM has been introduced to replace the Australian Active Service Medal (AASM) and Australian Service Medal for future ADF operations. The AOSM will be awarded to ADF members for service on operations recommended and approved as warranting recognition. Each declared operation will be recognised by the standard medal with a unique ribbon for each operation in the same way as the United Nations Medal is awarded. Where appropriate, an accumulated service device will recognise those who render additional prescribed periods of service on a particular operation. The first service declared for the AOSM is the range of border protection operations conducted since 1997.
There are currently four variants of the medal;
- Border Protection
- Greater Middle East Operations
- Special Operations
