Additionally, Dr Fraser has worked in the areas of Custodial Health and alcohol and drug dependence. The longer she practices medicine, the more certain she is that excellent health is not achieved with polypharmacy. 

Dr Fraser helps to manage the Low Carb Canberra private Facebook group and public page. She has been in nutritional ketosis since 2018. Outside of clinical practice, Dr Fraser is active with gardening, walking her dingo, hiking, and propagating pollinator-friendly plants.
