GGA chair, Peter Roberts, said Foss brought excellent skills and experience to the GGA which is a state-wide network of more than 60 grower groups.
"The GGA is at an exciting stage of growth and the Board is delighted to having someone of Rikki's calibre on board to lead the organisation through its next phase," Roberts said.
"Rikki has strong commercial capability, extensive agricultural networks and experience in a range of areas including strategy and planning, financial accountability and risk management.
"She takes on the CEO role from Niki Curtis, who has done an outstanding job guiding the organisation for the last year in an interim role, and the Board thanks her for her dedication and achievements."
Foss's most recent role has been with WA-based grain accumulation and export business, Plum Grove, where she has worked as a general manager and senior executive.
She has a rural background, and for several years has provided a grain consultancy role for her family's broadacre grain and livestock operation in WA's central grainbelt.
"Rikki will take up her position with the GGA on November 15, and her skillset and leadership style will be an asset for the organisation at a time when it is on an upward trajectory," Roberts said.
The GGA is in a $4.38 million, four-year Collaboration Agreement with the Department of Primary Industries and Regional Development and has been focused on strengthening its network of grower groups that connects strongly with industry.
