The in-form four-year-old will take on reigning Australian Horse of the Year, Via Sistina, in this Saturday's $3 million Group 1 TAB Champions Stakes.
Price bypassed a benchmark 90 race at the same track on Oaks Day, for which Zambardo was a short-priced favourite, for a meeting with the 11-time Group 1 winner in the 2000-metre event.
"I think we can go back to a benchmark 90 race any time," Price, who trains in partnership with Michael Kent Jr, said.
"It's run number six for him this prep – he's had a very good prep – and I just wanted to try him in that race as I want better horses in front of him.
"At Caulfield, and in a few other races, as soon as he hits the front he clocks off. We'll ride him cold and let him finish off.
"I would think, on all facts and figures, he's entitled to his long odds, but if he did run a place and get his rating up it sort of sets him up for the autumn to run in some better races.
"I think he is a nice horse, so I thought I'd make his last run 'chips in'."
