The Fourth World Congress of Behaviour Therapy, held on the Gold Coast of Queensland, Australia between July 4–8, 1992 was an important event in the professional calendars of many behaviour therapists internationally. It was hosted by the Australian Behaviour Modification Association, in association with the Association for the Advancement of Behavior Therapy, and the European Association of Behavior Therapy. This 3-yearly event provides an important opportunity for behaviour therapists from around the world to meet, socialise, exchange information, perspectives and ideas, and establish or extend colleague networks in a multicultural context. As the first World Congress on Behaviour Therapy to be held in the southern hemisphere, it achieved the same high standard of previous congresses in Israel, Washington, and Edinburgh, producing a balanced and stimulating program addressing most of the major areas of contemporary behaviour therapy research and clinical practice.
