A/Prof Dion Forstner, a conjoint Associate Professor with UNSW and has for worked for GenesisCare in NSW since 2018. Dion is based at St Vincent’s Hospital and Macquarie University Hospital and prior to this he was Head of Department of Radiation Oncology in South Western Sydney Local Health District for 9 years. His clinical focus is in the management of head, neck and skin cancers. He is site director at St Vincent’s.

Dion had an idyllic childhood growing up in Tasmania and graduated from the University of Tasmania with honours in 1994. He trained in radiation oncology in South Australia and for 15 years he practiced in the wonderfully diverse population of south-western Sydney. Dion set up multidisciplinary clinics for head neck and skin cancers with very broad multidisciplinary membership. He has an interest in the appropriate implementation of new technology, and ensuring sustainable funding of care. Dion has had many education roles and long had a passion for looking after our future – our trainees, and also in his leadership roles has been driven by a need to take great care of our existing workforce.

From 2014 to 2018 Dion headed up the professional body for radiation oncologists in Australia and New Zealand as Dean of Faculty of Radiation Oncology (FRO) at the Royal Australian and New Zealand College of Radiologists. In that role, he had a strong interest in quality, workforce, education and advocacy. He remains involved with RANZCR as Chair of the MBS working group – leading implementation of the completely new MBS schedule for radiation oncology and he is involved in training as a clinical supervisor, an assessor for accreditation of training sites and as an assessor of international medical graduates. Dion is President-elect of the Clinical Oncology Society of Australia (COSA) which is the peak national body representing health professionals from all disciplines whose work involves the care of cancer patients. He sits on the Boards of the COSA and Beyond Five and is a member of the NSW Government’s Radiation Advisory Council. He is a member of Cancer Australia’s Australian Cancer Plan Advisory Group.
