Psychiatrists work in a variety of settings including general and psychiatric hospitals, universities, community mental health services and public and private clinics. Many psychiatrists have a predominantly private practice. Others work mainly in hospitals or in prisons, or in a variety of public health facilities. Some psychiatrists work in more than one area, such as combining part time work in a public hospital with a private practice. Psychiatrists are also involved in a broad range of community issues and organisations, and are often called upon to assist both government and non-government agencies in the development of mental health policies and services.
