The former Labor leader held various portfolios including Minister for Primary Industries and Energy in the Australian Government from 1991 to 1996, and Minister for Regional Development from 2010 to 2013.
National Farmers Federation President Fiona Simson offered condolences to the Crean family on behalf of the agricultural community, saying Simon was a remarkable man who commanded the respect of the industry.
"He played a significant role in shaping agricultural policies and was a strong advocate for agriculture, for farmers and for free trade, both during and after his political career," Simson said.
"Simon actively supported the Landcare movement to encourage sustainable land management practices and championed the involvement of farmers and local communities.
"I've been honoured to have worked with him across a number of advisory positions and have always appreciated and respected his support for our industry and the people in it.
"Simon's efforts have contributed to the advancement of agriculture and the promotion of sustainable development in Australia's regional areas and for this, he leaves a legacy that will be remembered by farmers."
Grain Producers Australia said they were saddened to hear of Mr Crean's passing and recognised his engagement with the whole agriculture sector from grain growing through to the livestock, horticulture and fisheries industries.
GPA noted Crean was Minister for Primary Industries and Energy at a time of deep recession and crippling drought, and during his time as Minister for Trade was actively involved in establishing Free Trade Agreements. After his retirement from politics, Crean continued his engagement with the agriculture industry as Chair of the Livestock Exporters Council.
GPA Chair and WA grain producer, Barry Large, said Crean will be remembered as a sincere person who devoted his life to public service.
"In his various portfolios, he actively contributed to supporting and developing the agriculture and trade sectors," Large said.
"On behalf of the grains industry, we pass on our condolences to Mr Crean's family and other colleagues who had the privilege to work with him. He will be sadly missed."
