External quality audits are now being used in universities across the world to improve quality assurance, accountability for quality education and transparency of public funding of higher education. Some countries such as Australia, New Zealand, United Kingdom, Sweden and Denmark have had external quality audits for more than a decade but there has been limited research as to their impact. This study analyses the extent to which external audits in Australia have improved quality assurance in universities over the past 10 years. The analysis is based on discussions with 40 participants in a workshop on the effectiveness of audits and the review of 60 external quality audit reports between 2001 and December 2010. The research found that while external audits have led to an improvement in systems and processes in Australian universities, they have not necessarily improved the student experience. This lack of impact on the student experience in Australia is similar to other countries, according to the literature review. This study is timely in its analysis on the effectiveness of the current improvement-led audits, as government in Australia is in the process of renewing quality assurance arrangements of higher education institutions with a focus on standards and outcomes.
