Compiling genetics from leading Murray Grey producers from across the country, the Premier Murray Grey sale was hosted online via AuctionsPlus on Saturday.

Five sales in 12 months culminated in a world record-breaking event today at Oberon for the Humphries family of Wattle Grove Speckle Park.

The Nundle stud set a new world record for a Speckle Park cow of $70,000 at its stage one dispersal sale.

The Howard family could not have foreseen the huge effort, time and dedication required to hold a stud stock cattle sale, but it was all worthwhile when their offering of bulls, females, embryo and semen packages attracted strong buying support in the room and online.

The expansion of the Bonnydale black Simmental stud into Queensland is proving to be a fruitful one for Western Australia's Introvigne Grazing Co, with a top price more than double last year's inaugural showing, at Friday's sale at Roma.

Overall the Dubbo based Roseville Park Merino stud sold 235 rams to a $22,000 top and $3817 average.
