There are so many reasons to join COSA!
But don’t just take our word for it. Our members are at the core of everything we do and are our biggest advocates – here’s what they say.
What our members
are saying
Multidisciplinary collaboration and opportunities
"As an allied health professional, being involved as a COSA member has provided me with excellent opportunities for professional development, networking and collaboration with the widest range of multidisciplinary cancer health experts in Australia."

Dr Merran Findlay
Oncology Specialist Dietitian, Royal Prince Alfred Hospital. COSA Director. Previously Chair, COSA Nutrition Group
Our point of difference
“Many professional organisations are conservative and inward-looking. COSA is progressive, innovative and engaged. If you want to change the world of cancer, COSA is the place to be.”

Professor Bogda Koczwara AM
Director, Flinders Centre for Innovation in Cancer; Past President; Member, Integrative Oncology, Psycho-oncology and Survivorship Groups
Improve cancer care for all
“COSA connects me with like-minded colleagues who share the same passion to improve outcomes for cancer survivors.”

Professor Ray Chan
Director, Caring Futures Institute, Flinders University. Past Chair, COSA Survivorship Group. Chair, Financial Toxicity Working Group
Professional development for researchers
"COSA is invaluable for staying updated on oncology care innovations, which inform and enhance my research. It enables collaborations with practising healthcare professionals and fellow researchers, improving the quality of both basic and applied research. I highly recommend COSA to anyone seeking to advance their professional growth in oncology research."

Dr Ashley Hopkins
Senior Research Fellow, Flinders University; Epidemiology Group Chair
