Hailing from Bundaberg, the 66-year-old fell in love with racing at a young age.
Welsh’s father worked as a penciller for a bookmaker at Bundaberg that would travel around the Wide Bay region – and as far south as Gympie – to the races most Saturdays.
And, soon enough, a young Pat would follow his father into the game.
“He was a wizard, he knew everything about the betting,” Welsh recalled about his old man.
“My memories go way back into racing, I had posters on my wall as a kid of star jockeys or horses at the time.
“I have been attached to the racing industry for a long, long time.
“I slung the bag at a Melbourne Cup when I was just of legal age for a bookmaker at Bundaberg and he had a big winning day so the sling for me was good.”
The keen young journalist got his first opportunity with the company he would work almost 50 years for in 1975, still as a teenager.
He would dabble in news in the early days – before he focused his attention primarily on sport – but while it was the news rounds that were keeping him busy during the week, he was a regular at the track on a Saturday in a social sense.
Like his father, Welsh had an uncle who worked for a bookmaker at Eagle Farm.
“I would come along when I first started at 7 – which was 48 years ago now,” he said.
“I remember the big crowds down there near the bookmakers and the same in the mounting yard.
“It was a different beast in those days.
“There was over 100 bookies spread out from across the race track, which for people that go to the races now to think about that, it is just incredible.
“I love coming to the track, I love to get the buzz and the feel of the horses."
Racing Queensland CEO Brendan Parnell described Welsh as an "iconic Queenslander".
"Patty was one of racings great fans, as well as being a tragic punter and tipster," Parnell said.
"Racing was always on in the Channel 7 newsroom and there was always racing on a Saturday night bulletin.
"Patty has been a staunch supporter of racing in the Sunshine State and he got to see plenty of Melbourne Cups as well at Flemington.
"Punters are used to seeing him reporting on carnival race meetings all around Australia, so when people think of racing and punting - they think of Patty."
Parnell worked with Welsh in the Channel 7 newsroom on weekends for a period of a couple of years earlier in his career.
