Australia stylishly added to his growing roll of honour by winning the Juddmonte International Stakes at York.
Aidan O'Brien's dual Derby winner was tackling his elders for the first time but he oozed class throughout under the trainer's son, Joseph.
Another of the three-year-olds in the line-up, French Derby winner The Grey Gatsby, gave valiant chase but was beaten by a comfortable two lengths by the 8-13 favourite.
Joseph O'Brien said: "He was a bit fresh, his first run back after a while, but it was never really in doubt."
Kingfisher, Australia's pacemaker, set a generous pace but initially it was not quick enough for Mukhadram nor Arod, who both raced keenly.
The race hotted up with three furlongs to run as all six horses spread across the track.
Telescope briefly hit the front for Ryan Moore, but Joseph O'Brien, who had sweated down to below 9st for the first time in two years, had yet to ask the son of Galileo and Ouija Board for his main effort.
Once he did, the race was over.
The Grey Gatsby further enhanced his reputation by beating some solid older horses, while Telescope finished outside the first two for the first time in his career.
Aidan O'Brien said: "We're delighted. I couldn't be happier.
"He was ready for a racecourse gallop, that was where he was at.
"There's such prize-money here and it's such a prestigious race that it's very hard to gallop him at a racecourse rather than bring him here.
"The impressive thing about this horse is that he has a lot of speed, he travels very strong.
"Joseph nursed him down the straight.
"The lads will decide what's next, but we had in our head to come here and then Leopardstown (Irish Champion Stakes, 13 September) if everything went well."
