Epsom Derby winner Australia will not run in the Dubai Duty Free Irish Derby at the Curragh on 28 June if the ground is testing.
Aidan O'Brien commented in the past that Camelot, his 2012 Derby winner, was never the same after winning the 2012 Irish renewal in very soft conditions.
His jockey Joseph O'Brien, fresh from his victory on Australia in last Saturday's Investec Derby at Epsom, is keen to ride him over 10 furlongs in the future and warned his appearance at the Curragh is ground dependent.
"He's a very good horse, it all went pretty much to plan on the day," Joseph O'Brien told At The Races.
"He has a great temperament, he lobbed down to the start, left the gate and never picked up the bridle all the way. He was lovely and relaxed.
"I'd love to ride him back at a mile and a quarter and he is something to look forward to.
"The ground would have to be very nice for us to run him in the Irish Derby, we definitely wouldn't risk him on slow ground so the ground would have to be very nice."
