Corey Brown will replace the suspended Craig Williams on New Zealand lightweight hope Volkstok'n'barrell in Saturday's A$3 million group one Doncaster Handicap.

The Donna Logan and Chris Gibbs-trained four-year-old has won the group one Haunui Farm WFA Classic and the group one New Zealand Stakes at his last two starts and he will drop to 52.5kg in the Randwick mile.

Meanwhile, Debbie Kepitis is putting her trust in Chris Waller and Hugh Bowman as Winx heads to the Doncaster Mile as the shortest-priced favourite in almost a century.

The co-owner of the star mare has been in racing most of her life as the daughter of Bob Ingham, part of the famous Ingham family.


Things are a little different with Winx who she owns with a group of friends including Queensland businessman Peter Tighe.

Cox Plate winner Winx is bidding to win her ninth consecutive race and her sixth at group one level.

Kepitis was happy to draw barrier 11 of 15, believing it could be an omen.

"My mother was born on the 11th of the 11th so that could be lucky," Kepitis said.

The Doncaster market remained much the same as it was before yesterday's barrier draw with Winx the $1.85 favourite.

Her stablemate, last year's winner Kermadec, is the $6.50 second favourite.

Zac Purton, who rode the Waller-trained Sacred Falls to win the 2014 Doncaster, will ride Kermadec who carries 57kg, 6kg more than a year ago.

Meanwhile, Blake Shinn has been booked to ride What's The Story for Stephen McKee and Eddie Chippendale in the A$2 million group one Australian Derby.

Jockey Damian Browne has described Buffering's Dubai win as something special but he is already looking to the next group one assignment in Hong Kong.

Buffering burst on to the international scene when he won the group one Al Quoz Sprint at the weekend.

Browne arrived in Brisbane early yesterday morning and was met by a big media contingent. "It was certainly right up there in my career. He has been a great horse in Australia but to be able to go over there has taken it to a new level," Browne said.

Browne is looking forward to heading to Hong Kong for the Chairman's Sprint Prize on May 1.
