Recognised as the birthplace of the kelpie breed of Australian working dog, Casterton hosts the Australian Kelpie Muster, Working Dog Auction and Festival every June long weekend. It's been running since 1997 and enjoys enormous success, attracting those who are in the market for a working dog and those who just want to admire the animals' skills.
For people on sheep farms the dogs are a most important part of their working lives.
