James McDonald has given It's A Dundeel a glowing report after steering him to a decisive barrier trial win at Randwick.

The four-year-old worked home from midfield to put two lengths on Porcellanus, recording 1:11.3s for 1200 metres.

"He's definitely come back a stronger horse. It's scary how much he has improved," McDonald said.

It's A Dundeel's pre-training has been done by Murray Baker in New Zealand and he has been accompanied to Australia by stablemates Show The World and Atlante who will both be aimed at Group One races over the autumn.

Baker has mapped out a four-race Group One program for It's A Dundeel starting with the Chipping Norton Stakes on Saturday week followed at two-weekly intervals by the Ranvet Stakes, BMW and Queen Elizabeth Stakes.

It's A Dundeel won the three-year-old triple crown in Sydney last year before finishing second to Reliable Man in the Queen Elizabeth.

The 2014 Queen Elizabeth is the jewel in the crown of The Championships, the revamped and revalued Sydney carnival.

The April 19 race is worth $4 million, surpassing the Golden Slipper as Sydney's richest race.

It's A Dundeel has been displaced as the early favourite by Melbourne Cup winnner Fiorente who made a winning return in the Group Two Peter Young Stakes at Caulfield on Saturday.

The Chipping Norton will be It's A Dundeel's first race since his failure as favourite in the Cox Plate won by three-year-old Shamus Award.

His spring campaign was interrupted by a hoof abscess after he inflicted the only career defeat on the now-retired Atlantic Jewel in the Underwood Stakes and he went to the Cox Plate not having raced for five weeks.

In Monday's trial, It's A Dundeel sported the colours of his future home, Arrowfield Stud.

Arrowfield proprietor John Messara announced in September the stud would stand It's A Dundeel when he finished racing and subsequently acquired a 30 per cent share in the horse.
