A total of 966 allegedly ‘predatory’ open access publishers were examined to determine the nature of their ethical or unethical practices and the extent to which Australian academics were included on the editorial boards of their journals. An estimated 4,000 Australian academics (ca. 7% of the academic population) are on these journal boards. Of the publishers, 240 proved to be overtly fraudulent, the ethical status of the others remaining unresolved. About 86% of the Australian academics identified appeared on the editorial boards of journals belonging to those 240 publishers. Despite two decades of advocacy from librarians, there remains widespread ignorance of the existence of such fraudulent publishers, and more severe action is required. Reform proposals include naming the publisher in all references and in academic profiles and curriculum vitae. Universities are encouraged to take responsibility for publishing journals that replace those currently causing the problem. Institutions are urged to augment their current warnings and advice with formal policies, which will probably require a blacklist of unacceptable publishers. New formal policies for dealing with predatory publishers are currently being developed in some Australian universities.
