BankSA's rural price index shows South Australian winter crop production down 38 per cent in 2017-18 after poor weather. Barley output fell 40 per cent after wind and hail damage, and the state's wheat crop still reached 4.1 million tonnes.
A sharp fall in South Australian barley and wheat output tightens regional feed grain supply and supports local prices. The national wheat crop is also the smallest in about a decade, which is supportive for grain prices.
