The Australian Data Archive (ADA) provides a national service for the collection and preservation of digital research data and to make these data available for secondary analysis by academic researchers and other users. The archive is based in POLIS: the Social Policy Research Centre (formerly the ANU Centre for Social Research and Methods - CSRM) at the Australian National University (ANU). Along with Australian data, ADA is also a repository for studies conducted in other countries, particularly throughout the Asia-Pacific region. The ADA data catalogue includes studies from countries including New Zealand, Bangladesh, Cambodia, China and Indonesia.
