Hong Kong's Krisflyer International Sprint winner Green Birdie is now bound for Australia after his stunning win for trainer Caspar Fownes and jockey Mark Du Plessis in last night's Group 1 at Kranji in Singapore.

Green Birdie, who was originally trained in Australia by Brian Jenkins, posted his first win at the highest level when he finished powerfully to beat local hero Rocket Man by a neck in the $A806,000 1200-metre sprint.

Happy Zero was two-and-a-half lengths back in third, just ahead of Australia's Gold Trail and Eagle Falls in fourth and fifth respectively.

In the post race wrap, Fownes expressed his desire to return the horse to Australia; Rocket Man's trainer Patrick Shaw said a trip south was also a possibility for his horse while Gold Trail is now likely to head to England and Eagle Falls to return home to spell.

"He's a serious sprinter this horse," Fownes said of Green Birdie. "I've always felt that and now he's proved it. He did run second in a Hong Kong International Sprint and the talent's always been there. He really came on in the last four or five days here in Singapore and we've seen what he can do.

"He's an international sprinter now and that's the path we'll take with him. But I'm not that keen on the UK. I'd rather go to Australia. I've got family and friends there and there'll be some good races for him in the spring," said Fownes whose wife Alix is Australian.

Rocket Man was brave in defeat after veering wide on the home turn but was left again with second prize, as was the case last year when denied by another Hong Kong-trained sprinter in Sacred Kingdom.

"He couldn't show his normal kick on the ground tonight," said jockey Robbie Fradd.

Plans have not been confirmed for Rocket Man but a trip to Australia remains a “possibility” according to trainer Pat Shaw.

Gold Trail had the hearts fluttering of his supporters when he railed brilliantly on the turn and left Rocket Man in his wake. "I thought this can't be happening," said trainer Gary Portelli as Gold Trail looked the likely winner half way down the straight.

"He ran super. He skipped away from one of the fastest horses in the world and I doubt the rain helped his cause.

“I think he's run well enough to go to England for the King's Stand. That's 1000 metres which obviously suits him and it's a once in a lifetime opportunity so we'll give it serious consideration.”

Jockey Michael Rodd praised Gold Trail's effort. "He was just outstanding. He was good from the gates but then seemed lost. One ear going forward, the other going back and he was changing legs.

“It wasn't until Rocket Man moved up outside him that he started to travel better. He really kicked and had them at the 1100 (metres) but just tired in the last 50 metres or so," Rodd said.

David Hayes was not unhappy with Eagle Falls. "He ran well enough. Ollie (Damien Oliver) rode him beautifully but the wheels were spinning on the wet ground. You rarely get a wet track here but I guess that's just one of those things. He'll go home for a good spell and we'll have a serious horse next year. We've got Nicconi for Royal Ascot so that trip was never really that likely for this horse," Hayes said.
