With his wife Robyn, Neville farms the last 43 of 500 hectares in the valley of which Thomas Augustus Wolstenholme (Earl of Macclesfield) gained possession in 1860. Over the years the original Morville land was subdivided, and Neville and Robyn purchased their property in 1984. With water from the South East Irrigation Scheme they have been able to produce a variety of crops. An important part of their operation is the production of vegetable seed crops, usually cabbages. The seed is grown for South Pacific Seeds, which supplies seed under contract to many countries. Wheat is also grown to supply local poultry producers, and lucerne for hay. They also have 200 wool sheep.
Neville graduated with an honours degree in Agricultural Science from Sydney University in 1965 and spent six years in Papua New Guinea. He completed a doctorate at Nottingham in the UK, and in 1975 joined the School of Agriculture at the University of Tasmania as lecturer in Agronomy , becoming a senior lecturer in 1982. After a distinguished career in teaching and research in Agronomy he retired in 2006. He combined teaching with Landcare activities in the valley and worked as group research leader in the newly established Tasmanian Institute of Agriculture from 1997 to 2004 . He is now the Co-ordinator for Tasmania for the Crawford Fund, which supports international agricultural research for developing countries.
Neville has spent many years as a valued member of the CRPA Executive team, including as vice-president and secretary.
