About COSA
COSA has over 1000 members. These are doctors, nurses, scientists and allied health professionals involved in the clinical care of cancer patients.
COSA is the peak national body representing health professionals from all disciplines whose work involves the care of cancer patients. The overarching mission of COSA is to develop and maintain high-quality clinical care of cancer patients in Australia. Our members are doctors, nurses, scientists and all types of allied health professionals involved with cancer patients. We are allied with, and provide high-level clinical advice to, Cancer Council Australia.
Each year COSA hosts an Annual Scientific Meeting which brings together international and national speakers with COSA members and other interested professionals to share, discuss and learn about cancer research, diagnosis, treatment and care of cancer patients. This is the main platform for information exchange and learning each year. COSA funds grants and awards for COSA members, and hosts other cancer specific forums, workshops, professional days and seminars to build the knowledge of COSA members.
