Our team
BioAg operates with a small, efficient team of hard-working employees. Our area managers and agronomists serve South Australia, Victoria, New South Wales and Tasmania.
All our area managers are experienced on the land. They are located in regional areas across the southeastern states of Australia. From day to day they are either in the field helping farmers with advice and tailored programs or undertaking research including trials of BioAg programs and products.
Reception and accounts staff operate out of head office in Narrandera, providing customer service and team support.
Staff at the liquids plant at Narrandera and the solids facility near Geelong ensure our products are stored, maintained and shipped efficiently to your farm or distributor.
Our operations manager and leadership team work from a number of locations in south-east Australia, ensuring the smooth running of the company.
Our distributors and partners in Australia, the UK, New Zealand and South Korea work with their local customers to provide tailored programs and advice and supply BioAg products for improved productivity and yield for farms of all kinds.
