Dr Sarah Andrewartha is a Lecturer in Animal Science with the Tasmanian Institute of Agriculture.  She explores how environmental and production stressors impact the physiology and life history of adult and developing animals. She has worked with a wide range of animal models including poultry and aquaculture production animals.


Before joining the University of Tasmania, Sarah was a postdoctoral fellow at the CSIRO in Hobart using innovative biosensor technology to determine the wellbeing of aquaculture production animals in real time. Sarah was also an honourary lecturer with the University of Tasmania and supervised 3 PhD students examining how production stressors impact Atlantic salmon and abalone. Prior to this, Sarah studied epigenetic inheritance of hypoxia tolerance and how chicken embryos maintain acid-base homeostasis as a postdoctoral fellow at the University of North Texas in Denton (USA). Sarah was awarded her PhD from La Trobe University in Melbourne where she examined how wallabies, rats, crocodiles and goannas regulate their blood acid-base balance and meet their oxygen demands during acute thermal challenges.

Research Themes

Sarah’s research aligns to the University’s research theme of Environment, Resources and Sustainability. She studies how animals cope with production and environmental stress in our changing climate. She uses biologger/biosensor technologies to measure real-time physiology and studies how stress events can change the phenotype of developing animals. Ultimately, understanding how historic and real-time stress events impact the physiology of production animals will help growers form strategies for mitigating the effects of stressors and contribute to improved production sustainability.

Tasmanian Wool SmartFarm (2020)$50,000
This project will investigate the benefits to production and sustainability in the adoption and application of advanced management technologies (AMTs), such as the AWI SmartTags, in several high performing wool producing properties in Tasmania. The objective of this project is to (1) create national and global visibility of the on-farm adoption of AMTs, and (2) demonstrate the use of AMTs in supporting practices associated with high quality, sustainable and socially acceptable wool and sheep production systems. This phase 1 project will support a potentially longer-term commitment between contributing parties and broader collaboration with a range of supply chain stakeholders
