Americain is returning to his former trainer Alain De Royer-Dupre to be prepared for the 2012 Melbourne Cup.
Part-owner Colleen Bamford confirmed that the seven-year-old would be flown back to France last night after having an autumn campaign with David Hayes.
Bamford said the decision was made in the best interests of Americain who, for the last two years when trained by Dupre, made successful spring carnival raids.
He won the 2010 Geelong and Melbourne Cups while last year he took out the Moonee Valley Cup and Zipping Classic and was a luckless fourth to Dunaden in the Melbourne Cup.
His three runs for Hayes featured two Group One placings, in the Australian Cup (2000m) and The BMW (2400m), and a sixth to More Joyous in the Queen Elizabeth Stakes (2000m) at Randwick.
