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 Dabinett was first appointed to GPSA’s board in May 2014 and was subsequently elected for a two year term as Chairman in 2016. South Australia’s longstanding GM moratorium is what first inspired Wade to join the GPSA board, and he is now serving his second term as GPSA Chairman.

Wade is passionate about supply chain efficiency and would like to see a greater role for growers in this important aspect of their business. His areas of interest have expanded since he was first elected to the board. Over the next 2 years, Wade would like to see SA’s urban population exposed to more elements of agriculture to help raise career awareness, as well as to expand the agricultural industry’s social license. Financial literacy programs are also central to his vision for the continued growth of South Australian agriculture. Growers must have the necessary skills to successfully manage all aspects of their business.

Wade is involved in a family owned and managed mixed-farming enterprise based around Parilla growing grain, potatoes and livestock. He is an independent director of Duxton Broadacre Farms which is based in Forbes, NSW. Wade also represents regional Australia on the ABC Advisory Committee.

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.

David Malpas - Director

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 fund contributors. 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.

Tanja Morgan - Director

Tanja is based at Jabuk in the Southern Mallee and is part of a grain, hay and sheep production business.

She has also enjoyed time serving on the SAGIT Board and the Mallee Coorong NRM group.

Tanja feels strongly about the need to continue to advocate for agricultural R, D and E and contribute to policies that help growers farm profitably and sustainably.

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.

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.
