Jockey Jim Cassidy may be in the twilight of his career but he's confident of reaching a career milestone with his 100th Group One win aboard Sniper's Bullet in Saturday's Kingston Town Classic at Ascot in Perth.

Cassidy made a surprise riding return to Brisbane on Wednesday with three mounts for long-time friend Nick Moraitis at Eagle Farm, the venue of his first win at the elite level aboard Four Crowns in the 1981 Brisbane Cup.

Cassidy, 45, was only an 18-year-old apprentice at the time of his maiden Group One win aboard Four Crowns and has been sitting on 99 Group One wins since his last victory at the elite level on Red Dazzler in the 2006 Toorak Handicap at Caulfield.

"I was an apprentice to Pat Campbell when I won on Four Crowns," Cassidy recalled.

"I then came back and won the Melbourne Cup on Kiwi in 1983 before deciding to come over to Australia to live."

Cassidy began his "Aussie" career in Brisbane in June, 1984 but stayed only three months before being lured to Sydney to ride.

"Not many people remember it, but I actually started off riding in Australia in Brisbane," Cassidy said.

"I only stayed three months before I moved to Sydney in August that year."

Cassidy has fond memories of riding in Brisbane, and some that he'd prefer to forget.

The last time he rode in Brisbane he was involved in a horrific fall when he came to grief on the Ron Macrae-trained Bonza Crop at Eagle Farm in June last year.

The spill sidelined him for six months, leaving him with a broken ankle, four broken ribs and injuries to both knees.

Cassidy endured his most recent setback in April when he suffered multiple fractures to his right hand after falling from two-year-old Andretti after the running of the Baillieu Handicap at Randwick.

Cassidy has turned down a number of rides at Canterbury in Sydney on Thursday to head to Perth early to link up with Sniper's Bullet who has drawn barrier six in the 1800-metre weight-for-age feature.

Sniper's Bullet, who was an unlucky second to Gilded Venom in the Group One Railway Stakes (1600m) at Ascot last start, is yet to win past 1400 metres but that doesn't faze Cassidy.

"His last couple of runs have been terrific," he said.

"He meets Gilded Venom better at weight-for-age and he should be on the speed in this race.

"He'll look the winner at some stage in the straight."
