In 2008 when the Australian wheat industry deregulated, several small state-based industry associations consolidated to form the Grain Industry Association of WA or GIWA, with the merger of NACMA WA, Oilseeds WA, the Western Oat Alliance, the Western Region Barley Council and Pulse WA.
In 2011, the former Australian Grain Institute disbanded and rolled its’ AGI Capacity Building Project into GIWA, funded by CBH, DPIRD, GRDC, University of Western Australia, Curtin University, Murdoch University, the CBH Grower Advisory Council, Rabobank, Emerald, Bunge and Summit Fertilisers. Subsequently, the AGI Capacity Building Project became the GIWA Careers in Grain project in 2017, with the aim of attracting, upskilling and employing people in the WA grain industry.
In 2014 the former Grower Group Alliance project, originally funded by GRDC and hosted at UWA, transferred onto the GIWA ABN to be funded by DPIRD Royalties for Regions Funding. In 2018-19 the Grower Group Alliance project transitioned off the GIWA ABN to be funded by DPIRD in a new NFP grower group collaboration with DPIRD.
In 2018, the former Lupin Society of Australia disbanded and gifted residual funds to GIWA to be used for lupin industry development.
