"It's scary how good she's going," said trainer Peter Moody.
With regular rider Luke Nolen up, Black Caviar sat just behind the pace into the turn, and then in the blink of an eye was out in front by daylight. Nolen hardly moved his hands as the super mare cruised home effortlessly, finishing the 1,200 meters at the Moonee Valley course in 1:11.08.
Karuta Queen, the early leader, finished second and Fawkner was a late-closing third.
Moody said Black Caviar's next race likely will be the Aus-Group 1 T J Smith Stakes April 13 at Randwick.
"The only thing that could stop her is a wet track," he said.
