Gary Moore has high hopes he has an Australian Derby candidate on his hands in All Too Huiying.

The colt continues his racing development at Flemington on Thursday where he will try to extend his winning sequence to three.

If All Too Huiying can run in the top three in the Listed Seppelt Wines Stakes (1800m) he will stay in Melbourne for the Group Two Sandown Guineas (1600m) on November 18.

But the Rosehill trainer is looking further ahead with one of the most promising members of his stable.

"He's Group Two-placed as a two-year-old over the winter in Brisbane (Champagne Classic). He's a pretty classy animal," Moore said.

"There's no issue with his staying and if he continues to improve like I think he will he could be my Derby horse in the autumn."

He said All Too Huiying had settled in to his new surroundings and worked efficiently the Melbourne way on Friday.

"He's very laid back, there's no issues in that area," Moore said.

He was unfazed by All Too Huiying stepping up in class from a last-start success at Hawkesbury on October 26.

"It was always the plan to run him over 1800 metres at Flemington. I think it'll be right up his alley," Moore said.

"Unfortunately he's drawn a little bit wide but he's got good gate speed."

All Too Huiying, a $21 chance with the TAB, jumps from barrier 12 in the 15-horse field with Michael Walker to ride.

The Chris Waller-trained Sambro led the market at $3.90 on Wednesday as the colt backs up from a second in the Group Three Carbine Club Stakes (1600m) at Flemington on Saturday.
