Currently, several countries have operational coalitions or mechanisms for joint appeals for humanitarian response. Some mechanisms have been operational for over 50 years, whilst others have only been recently established. The most recently initiated was the Global Emergency Response Coalition in the United States launched on 17 July 2017. In recent years, several other countries including Australia, have examined the possibility of establishing joint appeal mechanisms for humanitarian response. This think piece explores the evidence for effectiveness, including advantages and challenges of existing joint mechanisms to enhance understanding on relevance and applicability in the Australian context.
