O'Brien: Australia 'another step up' from Guineas winner Camelot

Aidan O’Brien has described Australia as “a Derby horse we’ve not had the like of before” ahead of his tilt at the Investec-sponsored Classic at Epsom on June 7.

A son of Galileo out of the brilliant racemare Ouija Board, Australia burst onto the scene with a scintillating victory at Leopardstown last September and despite his stout breeding, was strongly fancied for the 2000 Guineas at Newmarket earlier this month.
