Ibicenco gained compensation for missing the cut for the Melbourne Cup by winning the Sportingbet Sandown Cup.
Luca Cumani's charge did not make the field for the Flemington feature earlier this month but stormed to victory in the two-mile Listed contest at Sandown.
Ibicenco made his challenge midway down the home straight under Glen Boss and scored by three-quarters of a length from Reuben Percival.
The OTI Racing-owned horse will now join Peter Moody's team in Australia.
OTI Racing's Terry Henderson said: "It's fantastic for the horse and for all the staff and Luca. But he'll get the sack now Luca, because the horse will go to Peter Moody.
"He's still a very young horse and the best appears still ahead of him."
