Mr Turnbull, a leader in the fruit-growing industry and fourth generation of a pioneering, Ardmona family, died on Thursday, March 3, aged 82, surrounded by his family.
Mr Turnbull was diagnosed with Parkinson’s disease in 2005.
Mr Turnbull was elected to the board of Ardmona Fruit Products in 1976 and the family became a major shareholder of the Mooroopna-based company.
He became the chairman of the board in 1980 and held the position for 23 years, overseeing the 2001 merger of SPC and Ardmona Fruit Products.
Before the merger, the two fruit processors were in competition for fruit supply, and Ardmona developed innovative packaging technology.
Under his chairmanship the company enjoyed a record profit.
He served as secretary/treasurer of the Ardmona Fruitgrowers Association for many years.
He was the chairman of the Tatura Research Station Advisory Committee and also served on the board of the Northern Pear Growers until 1991.
Mr Turnbull and his wife, Daphne, have supported community programs, including the annual Shepparton festival including hosting the Opera in the Orchard, in their garden at Findon House, Ardmona for many years.
Mr Turnbull is survived by Daphne, sons Chris, Alex and Philip and daughter Veronica.
A celebration of his life is being planned for later this week. Details to come.
