Grace Freeman

Grace grew up in Tasmania, living at Forth on the North-West coast and Relbia near Launceston where she attended Scotch Oakburn College. Grace was interested in rural life from a young age and this led her to study a Bachelor of Rural Science at the University of New England, NSW, which she completed in 2015. Studying at UNE enabled her to develop both practical and theoretical knowledge through the hands on learning provided. This study further developed Grace’s passion for the agriculture industry in particular beef production, animal health and nutrition.
During her university studies, Grace also had the chance to work on various sheep, cattle and cropping properties as well as undertaking full time employment at JBS Caroona Feedlot as Induction Foreperson in her final year of study. This practical experience has been invaluable to Grace in increasing her knowledge of all aspects of the feedlot industry.
Grace joined NSA in January 2016 and looks forward to continuing her studies and developing a career as a feedlot consultant.
