Join Us

The Australian Citizen Science Association is a vibrant and growing community citizen science enthusiasts! Made up of both professionals and amateurs, ACSA membership is open to anyone who is passionate about citizen science. As an ACSA member, you’ll be able to share ideas, pose questions, collaborate on projects, attend networking events and connect with people working, volunteering or fascinated  in citizen science.

ACSA became the first association dedicated to citizen science in Australia with a Commonwealth Government grant from Inspiring Australia in 2014.  One of our primary goals was to secure the long-term financial stability of the association. Paid membership helps us to achieve this goal!
