Our executive consists of our Chief Executive Officer, our National Medical Director and our Chief Operating Officer.
Chief Executive Officer
The OTA welcomed Helen Grinbergs as the new CEO of the Australian Organ and Tissue Donation and Transplantation Authority in October 2026.
With a career spanning heritage conservation, climate change, aged care and public health, Helen has led some of the Australian Government's most significant reform agendas, including aged care reforms following the Royal Commission. She has held senior leadership roles in international and domestic policy, strategy and coordination, program development and delivery, regulatory compliance, agency establishment, governance, and system and organisational reform.
Most recently, Helen led work to establish the Australian Centre for Disease Control, helping to create a new national institution focused on delivering trusted, timely health advice and improving health outcomes for Australians.
Beginning her career as an archaeologist before discovering a passion for policy, Helen brings a practical, outcomes-focused leadership style centred on collaboration, transparency and solving complex problems. She is passionate about improving health and wellbeing, particularly for vulnerable populations, and in her spare time enjoys skiing, theatre and following the exploits of her son's punk band.
National Medical Director
Associate Professor Helen Opdam MBBS FRACP FCICM was appointed as the OTA National Medical Director in 2014. She is a Senior Intensive Care Specialist at the Austin Hospital in Melbourne and Director of Warringal Private Hospital Intensive Care Unit.
Helen is responsible for providing expert clinical advice to the OTA CEO, DonateLife Network staff, clinical organisations, the Australian Government Department of Health and Aged Care and other government agencies and key stakeholder groups. She is the current President of the International Society for Organ Donation Professionals. Helen participates both nationally and internationally on working groups and committees, as a conference speaker, and as an author for medical journal and guideline publications. Helen has been involved in organ donation since 1998, initially in developing an audit to determine the potential for organ donation. This process has evolved into the current DonateLife audit that provides key metrics for Australia’s donation performance and monitors the effective implementation of the national program within hospitals. Helen was the inaugural Victorian State Medical Director for organ and tissue donation at the initiation of the DonateLife program in 2009
