In Australia, crop harvests may be affected due to frosts in some parts of the New South Wales State. Recall, last year, according to the "GrainCorp Ltd", this region was the largest wheat producing region in the country.
Farms located in the Southern part of the New South Wales state recently recorded frosts, which will have a negative impact on crop yields. Harvest decline may probably occur in the West of Victoria State, too.
In Chicago, in the current year, the futures contracts on wheat traded at 11% price loss due to expected world grain production of the given crop type to a record 708.9 million tons. 
According to experts’ September forecasts, Australian farmers may harvest approximately 24.5 million tons off of their fields.
According to the forecasts of the Commonwealth Bank of Australia, due to less than favorable weather conditions on the East coast, level of harvest has been lowered by 6.5%, down to 23.6 million tons.
Yesterday (October 29), on the Chicago Mercantile Exchange CBOT, wheat for December delivery fell 0.4%, to 6.8775 dollars per bushel (27.2 kg). According to the estimates of the USDA, in the 2013-14 season Australia could become the fourth largest exporter of wheat in the world.
