Shauna grew up in Mallala and attended high school in Gawler before completing her specialist training across major Adelaide hospitals and the Royal Darwin Hospital. She has also worked in regional and remote settings throughout the Northern Territory.

Most recently, Shauna completed a clinical fellowship at the Leeds Liver Unit in the United Kingdom, where she gained further experience in complex and advanced liver disease and liver transplantation.
