Grain Producers SA’s Board of Directors is elected by SA grain growers 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.

David Malpas - Vice Chairman

David operates a mixed farming enterprise with his wife Angela, near Lucindale in the South East, comprised of cropping, sheep and cattle. He is a past member of the SAFF Grains Committee and former treasurer. David has been a member of Grain Producers SA since its inception and would like to see it continue to grow as the voice of the levy-payers. David believes grain producers need an efficient and competitive environment to be able to remain profitable as a farming enterprise. He sees GPSA having a large role in this as the voice of South Australian grain producers, to represent them as a united body to business and governments to drive change for the industry.

Adrian McCabe

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.

Jared Sampson - Director

After spending time on the other side of the fence working for Elders and Pasture Genetics, Jared returned to the family farm at Warramboo in 2012, growing wheat and barley and running a self-replacing Merino flock. He says GPSA provides the opportunity to contribute to a number of key issues facing the grains industry, particularly land access and transparency of the process involved, which is of considerable importance to not only our local community but the whole industry. With a mix of youth and experience, GPSA will hopefully continue to offer strong advocacy and representation for all growers, while encouraging the next generation to take a proactive approach in developing and promoting our industry.

Headshot of Dion Woolford

Dion Woolford - Director

Dion farms with his wife Chelsea and his parents near Kimba, cropping 4500 hectares to mostly wheat, barley and vetch for feed and running 5000 sheep under the prefix Karawatha Park. Dion says he is excited by the opportunity to work with the GPSA Board because the issues that GPSA deals with through its policy and advocacy role affects producers throughout SA. He is keen to contribute to the broad range of issues which GPSA covers, such as how supply chain costs affect farmers and the importance of machinery movement and the capacity to operate road trains on EP. Another important issue he believes in is regulation around access to technology, such as genetically modified crops to help boost productivity.
