The Australian & New Zealand Intensive Care Society was formed in 1975 and is the premier representative body for specialists practising intensive care medicine in Australia and New Zealand. The society has over 770 members spread across the two countries and internationally.

Despite its relatively small size, ANZICS is one of the leading advocates of intensive care related matters, through the activities of the Clinical Trials Group and the adult and paediatric outcomes databases (CORE). The society is also responsible for studying the safety and quality in intensive care practice, the development of clinical practice guidelines and the management of the organ donor process in intensive care units. ANZICS plays an important role in fostering opportunities and partnerships between members, stakeholders and government bodies. ANZICS is an active member of the Asia-Pacific Association for Critical Care Medicine and the World Federation of Societies for Intensive and Critical Care Medicine.
