Hong Kong trainer Caspar Fownes is not concerned by the potential delay in travel plans for Melbourne spring carnival contender Lucky Nine.

Typhoon Usagi has forced the cancellation of flights out of Hong Kong from Sunday night with the sprinter's scheduled to leave on Monday.

Fownes said Lucky Nine had done the necessary work to have him fit when he does get to Melbourne where he will be aimed at the Manikato Stakes on October 25 and the Patinack Farm Classic on November 9.

"I'm sure the flight will be cancelled now with the typhoon but it's not really a problem this far out from the races," Fownes told the South China Morning Post.

"Usually there will be another flight within 48 hours, so we'll get him down there on that. Anyway, he had a stronger workout than I wanted on Friday morning ... so it will give him another day or two to get over it."

Jockey Brett Prebble, who delayed his return to Hong Kong this season until after the Melbourne spring carnival, will be his work partner and race rider in Australia.

"Brett will be on him in all his gallops and that's going to be a big plus," Fownes said.

"I think it's the best he's been for a long time, maybe ever.

"Even though he's six, I can see him going to a whole new level this season."

Lucky Nine won the 2011 International Sprint on home soil and took out the KrisFlyer Sprint in Singapore earlier this year.

Sunday's race meeting at Sha Tin was called off because of the approaching storm and transferred to the end of next month.
