Prepared by Peter Moody, the dashing bay was sent to the lead by Kerrin McEvoy as he was at his previous win in the Group III ATC Carbine Club Stakes over 1600 metres and achieved the same outcome over the longer 2000 metre trip.
He bowled along at a comfortable clip and then powered clear to win by more than a length to win with authority.
A $120,000 Magic Millions purchase for Slade Bloodstock from the Coolmore draft, Hi World has won four races and placed twice from just seven starts earning over $195,000 in prizemoney for his big team of Slade Bloodstock owners.
"He's a nice colt, an exciting prospect and got the job done nicely again," said Moody.
"He'll go to the paddock now and rest up for the spring.
"I think he can take the step and be a serious horse, whether that be in the handicaps or event at weight-for-age."
Yet another stakes-winner foaled and raised at Coolmore, Hi World is a half-brother to stakes-winner Loveyamadly and Group I placed American Crew being the fifth winner from Danehill Dancer (IRE) mare Beauty World, who comes from the old Stage Hit family.
Hi World is one of six Australian stakes-winners this season for ill-fated High Chaparral, who will have two more crops of yearlings to sell here.
