Saga Systems is a principal-led consultancy, supported by a network of subject matter experts across NSW, VIC and QLD.

Tiffany is passionate about helping organisations find the story within their system. She is drawn to work that involves listening carefully, understanding different perspectives, and using research and evidence to make sense of what is happening in practice and inform what comes next.
Tiffany has nearly 20 years of experience working across health, research, government and the not-for-profit sector. Her work has spanned cancer care and survivorship, patient-reported outcomes, health literacy, First Nations health, primary care, chronic disease, and community physical activity and nutrition initiatives. She brings particular expertise in research and evaluation within complex settings, where outcomes are shaped by people, relationships, service design, context and history as much as by the activities themselves.
Tiffany holds a PhD, a Master of Health Services Management and Facility Planning, a Master of Public Health, and a Bachelor of Science in Population Health and International Studies.
In 2026, Tiffany is working across a range of research and evaluation projects, including primary care quality improvement, interprofessional education and cancer survivorship. She also works with research teams and organisations to develop competitive grant applications, contributing to project conceptualisation, research and evaluation design, methodology and grant writing.
Jessica brings a climate and environmental lens to sense-making and communication, supporting decisions involving complex trade-offs and long-term consequences. Drawing on her work in marine conservation and climate advocacy, she helps translate evidence and lived experience into clear, credible narratives that support informed action.
Jessica has commenced a Master of Arts in Environment and holds a Graduate Certificate in Peace Studies and Conflict Resolution, and a Bachelor of Arts in Politics, History, and International Relations.
