Michele Hemmings

Patient Pathways Telehealth Nurse

Michele began her career in 1984 as a Registered Nurse at Sydney Hospital. She continued to work in the hospital system administering acute and chronic paediatric care and later found herself in the community sector, looking after children with chronic care needs, paediatric case management and as a clinical nurse consultant. She went on to receive a degree in paediatrics, family and community care.

Michele’s passion to help families allowed her to travel to the Middle East and Africa to work in a high care paediatrics unit with a community focus. She found this opportunity educational on a cultural level, where she would exchange western magazines with the local mothers for coffee and beads they made. These encounters enforced a philosophy Michele lives by, which is "To give love by a simple heart by a simple act of caring is better than a thousand heads bent in prayer." (Mahatma Gandhi)

When Michele began her family in 1990, it prompted a change in her career. Michele began work in adolescent health, focusing on school health and later, youth within the Justice health system - a rewarding experience that saw many ‘troubled teens’ turn their lives around. It wasn’t until 2017 that Michele made the transition into adult care, primarily working in aged care.
