The CSIRO Staff Association represents the industrial and professional interests of employees of the CSIRO (Commonwealth Scientific & Industrial Research Organisation), the Anglo-Australian Observatory, and Co-operative Research Centres and supports members in the National Measurement Institute who were formerly staff of the National Measurement Laboratory in CSIRO prior to July 2004.

The Staff Association has around 3,000 members, that is, approximately half of all CSIRO staff, across every work area and geographical location in Australia.
