Humanitarian Overseas Service Medal

The Humanitarian Overseas Service Medal is an award in the Australian honours system. The award is presented to those who perform humanitarian service in a foreign country, in particular those working in dangerous environments or conditions or during a humanitarian crisis. The award was introduced by letters patent on 16 April 1999, following a review of the Australian honours and awards system beginning in 1995.

Potential recipients have to prove they worked for a minimum of 30 days in the location depicted by the clasp, during a period of time set in the award criteria. In addition, potential recipients have to be working for an aid organisation recognised by the criteria or with a United Nations taskforce during that timeframe. In 2005, special criteria were established for people working during the 2004 Indian Ocean earthquake or the 2005 Nias–Simeulue earthquake, with a maximum time period of 7 or 14 days depending on the time frame.

The medal was originally intended as a civilian award, in parallel with the Australian Service Medal and the Police Overseas Service Medal, and until 2005 the Australian Defence Force had never been declared an eligible organisation.
