The Casterton Kelpie Association has cancelled its 2020 Australian Kelpie Muster.
"Whilst this is a great disappointment for all involved and for our community, the committee have been left with no option as the COVID-19 situation in Victoria is still not contained," president Karen Stephens said.
"The Casterton Kelpie Association will now put all its energy into working towards our event in 2021, which will be significant as we celebrate the 25th Year of the Working Dog Auction."
She said the 2021 event would also reach a total of $3 million in auction results for working dogs.
"As at the 2019 Working Dog Auction, the total amount sold was $2,912,709 - so this will be broken," she said.
Usually held on the long weekend in June, the 2020 muster had been postponed until October.
