She had 2 lengths to spare at the post and cut out the 1200m on a dead track in a slick 1:08.89.
Shees Flawless is trained by Roger James, who was at the Gold Coast with his stable star Silent Achiever, for a syndicate that includes co-breeder and part-owner Peter Walker.
"She's got a great cruising speed," he said. "She's out of a Fastnet Rock mare and that's where the strength comes from."
Walker also shared in the ownership of Shees Flawless' group one winning sire Fully Fledged, whose career at stud has waned.
"I had to let the stallion go - nobody wanted to stand him," he said.
Like the Trentham winner Hover, Shees Flawless was the subject of a $50,000 win bet and her supporter had no concerns with a comprehensive defeat of her stablemate Tavy with Passing Shot third ahead of Perfect Fit.
