Grain Producers SA’s Board of Directors is elected by grain growers from across South Australia at the organisation’s Annual General Meeting. Directors are elected for a two-year term and meet up to eight times per year.


GPSA Directors bring skills, knowledge and experience from many parts of the grains industry, including crop production, research, merchandising, marketing, storage, transport and logistics. The Board determines GPSA policy in consultation with grain growers, farming systems groups and other grains industry bodies. GPSA Directors participate in regular regional and state forums to gain input from all sectors of the industry.

The Board is comprised of seven non-executive directors and its members can also appoint up to two independent directors, as outlined in GPSA’s Constitution.

Wade Dabinett - Chairman

Wade returned to his family farm at Parilla in 2011 to help run the growing business, including 4500 hectares of crops as well as potatoes and livestock. With experience in the grain trading, storage and handling industry, he is keen for other growers, particularly young farmers, to gain skills in grain selling and business management. He sees a great future in the grain industry, and would like to see more farmers engaged with GPSA and young farmers upskilled to be part of the future of the industry. Wade joined the GPSA Board in May 2014 and was elected Chairman at the 2016 AGM. He also chairs GPSA’s Transport and Supply Chain Sub-Committee.

Adrian McCabe - Director

Adrian is a grain grower at Hamley Bridge, where he crops wheat, canola, beans and durum. His family has been farming in the Mid North since 1956 and also farms on the western slopes of New South Wales. He is a board member of the Southern Durum Growers Association, a member of Fat Farmers and a previous member of the SA Farmers Federation.

These include the need to invest in country road infrastructure, reduce spiralling grain handling costs, gain access to GM crops and further promote the grains industry as a major contributor to the state’s economy.

Peter Polkinghorne - Director

Peter is a grain producer near Ceduna. He was born and bred on Yorke Peninsula, moved to Coonalpyn, where he mostly grew wool in the 1980s, then relocated to the West Coast 22 years ago. Wheat is the biggest crop grown and he and his family also run 2500 Dorpers. Peter wants to see profitable and sustainable grain production on the West Coast with access to a secure and efficient port. He says keeping the Thevenard port viable by upgrading it is the biggest issue for West Coast producers. At present, the channels are not deep and so only small ships with up to 25,000-tonne capacity are permitted.
