Making her first start since picking up an injury in a narrow victory at Royal Ascot last June, the six-year-old won the Black Caviar Lightning Stakes to maintain her perfect record with a 23rd win from as many starts.
Black Caviar led from the start and widened the gap from the chasing pack to win by 2-1/2 lengths in a time of 55.42 seconds, 0.08 faster than the previous best set by Special in 1988.
Chasing home the hot favourite were Group One-winning stable-mate Moment Of Change and Golden Archer as horses trained by Peter Moody filled the first three places.
Moody later admitted he was overwhelmed to see the mare racing again after her eight-month absence as she captured her third consecutive Lightning Stakes title.
"I'm just so proud to have her back," Moody told reporters. "I said to my girls, I think it is the first time I have been nervous for a long time.
"I am a little bit emotional for the first time."
Jockey Luke Nolen, who was criticised for easing off in the Ascot race and almost getting caught on the line, said Black Caviar was suffering a bit from the intense heat at the start of the sprint.
"I didn't drop me hands on her today," Nolen quipped. "I just sat there and squeezed.
"I think she was knocked around a bit by the heat today. But she was pretty good once we got going.
"She just continues to amaze me."
Black Caviar's immediate future remains undetermined, but it could include one more run in Melbourne and further races in Sydney and possibly Brisbane before she retires to stud.
