In retirement, Roberts is being acknowledged for his enormous service to the industry, with his job effectively being a seven-day-a-week role.
But, it all started with a slice of luck all those decades ago.
From the age of 20 until he was about 30, Roberts worked on a cane farm at Tully in Far North Queensland driving a tractor and sugar harvesting.
By chance, he was at a family barbecue in Brisbane and got talking to a friend of his father-in-law who worked at Doomben in those days.
Roberts was asked if he could drive a tractor and if he wanted to start on Monday morning.
“That was the 7th of September in 1987 and I have been here ever since,” he said with a chuckle.
Roberts quickly rose through the ranks, working as a machine operator at the start, before becoming a team leader then racecourse supervisor.
“I was told by my boss at the time that I showed a bit of potential and I was offered the chance to do a grass management course,” he recalls.
