Buenos Noches takes his first step back in a 900m Rosehill barrier trial on Thursday, ahead of his resumption in the Expressway Stakes (1200m) at Randwick on February 17.
He will then head south for the Group 1 Yulong Newmarket Handicap (1200m) at Flemington on Super Saturday, March 9.
"He will most likely go down to Melbourne for the Newmarket. "We are definitely focused on winning Group Ones," Smith told Sky Racing radio.
Smith said connections had fielded some inquiries from studs regarding Buenos Noches, but no deals had been made.
However, he expected that to change if the horse could claim a major, given most of the other top sprinters of his age group, such as 2022 Everest winner Giga Kick, were geldings.
"We've had a few nibbles at him," Smith said.
"He's obviously a really good horse and probably the best sprinting colt in Australia - I don't think there are any other colts of his age as good as him.
"We've just got to get the Group One on the board and then I'm sure the studs will come looking for him."
