AWOCA has been held at many venues in Australia (last year at Ayers Rock, a world heritage site), once in Korea, three times in Indonesia. At the Ayers Rock conference, in view of the increased recognition of AWOCA, the participants decided unanimously to upgrade, to focus more on high-quality presentations, but also on problems sessions, and to have the Proceedings published by a well-known academic publisher. To provide more flexibility in venue for the upgraded conference, and to make its results more widely accessible, it has also been renamed. All submissions to IWOCA will be refereed by three referees selected by Program Committee members.

IWOCA 2007 will be held in the vicinity of Newcastle at Rafferty's Resort, Lake Macquarie. Newcastle started life as a steel town, but has been transformed into a charming small seaside city close to the renowned Hunter Valley wine-growing area and a centre of picturesque resort towns on the New South Wales coast. The fourth day of the workshop will be taken up with an optional tour of spectacular scenic areas, arts-and-crafts centres, and some of the finest wineries in the world.
