Connections say Black Caviar may have run her final race after a dramatic victory in the Diamond Jubilee Stakes at Royal Ascot on Saturday.
Jockey Luke Nolen admitted an error of judgment in easing up prematurely in the Group One contest but still had a head to spare over Moonlight Cloud at the line.
She was stretching her unbeaten record to 22 but trainer Peter Moody felt his star mare was far from her best on her first start outside Australia.
"She'll go into quarantine now, so let's get her home," he said.
"This was always going to be the greatest risk of her career and for the last five or six runs we've always been prepared it might be her last.
"Hopefully that's not the case today but if she's as tired and worn out when she gets home she may have graced the track for the final time.
"I won't hesitate in any shape or form, but let's not put the cart before the horse. It's just a shame your public haven't seen as great a filly as she is. She's not going to improve from here on in as she's a six-year-old by your time, five by ours, but I'm so proud of her."
Black Caviar was later inspected by the on-course vets and given the all-clear.
