The first Diamantina Droughtmaster Bull & Female Sale was held in 2004 at the Winton Saleyards. The idea for a sale was conceived by a group of like-minded Droughtmaster breeders who recognised that an opportunity to sell western-bred bulls and females existed in Winton. Eight vendors presented bulls at the inaugural sale. This number has now grown to thirteen.
An innovative feature of the Sale is the commercial female sale where approximately 1000 purebred Droughtmaster females are on offer each year. The Diamantina Sale has the honour of presenting the largest yarding of top quality Droughtmaster females for sale in Australia. A small number of Registered females have also been sold at previous sales.
The Diamantina Sale has proven so successful at putting Winton on the map as a recognized selling centre that two other breeds now hold an annual sale there. Fortnightly Fat & Store Sales have resumed after a long absence. In 2009 the Winton Shire Council erected a covered area over the selling ring with plans for a permanent selling ring and further improvements to the yards on the drawing board.
