As the owner-operator of a horse transport business, trainer Don Robb knows how to take care of the needs of travelling thoroughbreds.

So he has no qualms about taking Big Bonanza from Wyong to Melbourne to race at Moonee Valley on Saturday in preparation for his bid to go one better than last year in next month's Ramornie Handicap.

Robb also entered the gelding for the Winter Dash at Randwick but said the experience of Big Bonanza's unplaced effort in last year's June Stakes convinced him Moonee Valley was the best option.

"He didn't like Randwick and Moonee Valley suits on-pace horses," Robb said.

"It's easy to get him to Melbourne. I have my own transport business and it's no big deal.

"The horse works in both directions all the time so I don't think that will be a problem.

"Nicholas Hall has been booked to ride him."

Big Bonanza finished second to multiple stakes winner Youthful Jack in the 2013 Ramornie (1200m) at Grafton but things went horribly wrong not long after.

"He hurt a hock in a paddock accident and had to have a couple of operations on it," Robb said.

"It has been a long process getting it right."

At his only start since the 2013 Ramornie, Big Bonanza over-raced in last month's Listed Chief De Beers won by Cape Kidnappers at Doomben and finished unplaced.

He has since had a barrier trial to get him ready for his next assignment.

Big Bonanza is one of 29 entries for the 1200m open sprint at Moonee Valley and has 57kg.

Unanimously, trained by Matthew Dale at Canberra and also entered for Randwick, is the equal topweight for the Moonee Valley sprint with Le Bonsir.

The Mick Price-trained Le Bonsir finished third in the Group One Moir Stakes at the track last September behind stablemate Samaready and Buffering.
