He was dubbed "King" after becoming the first Singapore jockey to smash through the 100 winners in a season, recording a remarkable 106 victories from 355 rides to win the premiership in 2007.
Despite the title, Callow has always preferred to fly beneath the radar of publicity, more often than not an Australian jockey's lifeline.
"It's not something I care about," he told Matt Stewart in a 2012 Herald Sun interview. "It's not me at all. All I do is go out there and do the job.
"Maybe when I'm 60 I might want to remember it."
The 38-year-old has been a respected, tough rider in Melbourne, but like his personality he never created bright lights despite winning a Victoria Derby on Denicio and a Caulfield and Australian Guineas.
He has often preferred to ride at the lesser Saturday meetings in Victoria and in the past few weeks took a Queensland holiday, again shunning the major tracks to ride at Mackay and Townsville.
From day one Tommy Berry and his twin brother, Nathan, have had a touch of Hollywood about them, but the glamour has not turned their heads, which is an enormous tribute to their ability to keep their feetfirmly planted.
Yet there is an edge of delightful mischief about the pair, something Tommy displayed when he joined the personality-plus pair of Greg Radley and Malcolm Johnston on Off the Rails. In the early days the blond 23-year-olds were not averse to playing pranks by one twin winning a race and the other turning up for the birdcage presentation.
It has been a great year for the twins, Tommy Berry winning the world's richest 2-year-old race, the Golden Slipper, on Gai Waterhouse's Overreach and Nathan climbing up to a new level in taking the recent A$2 million Inglis Classic for former New Zealand trainer Bjorn Baker.
Tommy Berry is being described by Hong Kong trainer John Moore as the next Darren Beadman. Last year Berry landed a three-month contract to ride in Hong Kong and within hours of arriving won the group one QEII Cup on Military Attack.
And then you have Kerrin McEvoy. There has never been a more grounded young jockey in this part of the world than the former South Australian.
At just 20 he caused a sensation by winning the 2000 Melbourne Cup aboard the Mike Moroney-trained Brew. If that didn't turn his head nothing was going to and so it proved when he became the No 2 European jockey behind legendary Frankie Dettori for the global racing giant Godolphin and its principal, Sheikh Mohammed.
He is now back in Australia continuing to ride for Godolphin.
McEvoy has always had maturity beyond his years and yet, interestingly, now as a 33-year-old he looks almost as young as he did the day he won the Melbourne Cup.
The Australian trio have difficult jobs.
Berry has to somehow weave some magic to find a suitable passage from the outside No 14 gate for in-form filly Way In.
Callow has to come out of an easier, but still awkward barrier No 9 on Dragon Lair.
And McEvoy has the easier task from No 5 on Massale, who is slightly less experienced than some of the opposition.
