In 1998-99 there were 1.75 million tonnes of cereal hay produced in Australia at yield of 4 tonnes DM/ha average.  During that period, over 400,000 tonnes of cereal hay was exported, mostly to Japan (most of this being oaten hay, plants in vegetative to soft dough stage ).  Japan is a growing market for Australian exports, particularly for their dairy industry.  Domestic prices for oaten hay range from A$70-165 (U.S.$40 -100) depending mostly on time of year, being higher in winter when demand is high.  Quality also affects price,  but economic information is not available.
