He began his dog trials career with the club when just 10 years old. Now aged 71, he has never missed a competition.
But these days he does it for the fun, although he has won a few trophies in his time, particularly in the 1950s and 1960s when he ran five dogs.
"I always sold the winning ones," he said.
More than 150 dog triallists competed at Millers Flat during the three-day event, which ended yesterday.
Mr Parker said his favourite heading dog, Chappie, named after a friend who died the day the pup was born, came from a long line of good dogs which he had kept going for 50 years.
There had been five generations of his family compete at the Millers Flat trials, and he proudly recalled how his father James and his uncle Joseph kept the collie club going through the Depression.
He said the trials had been cancelled once, in 1981, when 20cm of snow fell.
"There were no minutes for two years during the war in 1941-42, but the club did run a local day each year."
Mr Parker recalled how "in the old days" the competitions often came down to one or two top dogs and triallists would have bets in the pub on which would win.
"These days, I joke about how they [the dog owners] are going to need to get a manicurist up here to 'do the dogs up' before they run," he said, chuckling.
