A stunning Australian debut from import Jet Away at Bendigo had trainer David Hayes declaring the galloper a Caulfield Cup contender.

The former UK-based horse was bought from England last year as a potential Cups horse and couldn't have been much more impressive coming from near last on the turn to take out Saturday's $150,000 Golden Mile (1600m) running away.

The six-year-old, who started $6, scored by 1-1/4 lengths over Zabisco ($16) with a short half-head to Prizum ($21) third.

"We hope he's a Caulfield Cup horse," Hayes said.

With that in mind, Jet Away will press on to the Group Three Easter Cup (2000m) at Caulfield at the end of the month before going to Sydney for the Group One Queen Elizabeth Stakes (2000m).

"These days when they are lowly-rated you've got to get their rating up to get into the Cups," Hayes said.

Jet Away has a win over last year's Melbourne Cup runner-up Fiorente to his credit in England and Hayes said the galloper had "good horse written all over him".

The resurgent Hayes wasn't finished there at Bendigo as three-year-old Bradman capped a big day for the stable with an upset win in the $150,000 Bendigo Guineas (1400m).

Bradman ($51) came from last on the turn and powered through between runners under jockey Nick Hall to grab Ninth Legion ($5) in the last stride.

He is likely to progress to Sydney for races below the top level while Jet Away's jockey Stephen Baster believes the import can be competitive in whatever he runs in.

Baster settled Jet Away near the tail of the field but when he brought him to the outside in the straight the entire lengthened and swooped past his rivals.

"(David) thought he would just be too good for them and he was spot on," Baster said.

"He feels like a good horse. They've got a nice one there to look forward to."
