Oaks winning filly Princess Jenni has thrived during her winter spell in the sun in Queensland and has began shedding the kilograms in the prelude to her spring campaign.

Trainer David Brideoake said the Group One-winning filly returned to his stable at Mornington last week in magnificent order.

Princess Jenni won the Australasian Oaks at Morphettville in early May while at her most recent outing she finished sixth to Winning Ways in the Queensland Oaks on June 1.

Brideoake said her spring campaign was being mapped around the Group One Empire Rose Stakes (1600m) at Flemington on the opening day of the Melbourne Cup carnival.

"She came to me last week after being in pre-training in Queensland," Brideoake said.

"She came back in very, very good shape.

"She's got a really good coat on her and was about 22 kilos heavier than her racing weight so we've got a lot to work with.

"She'll have a couple of runs culminating in the Empire Rose at Flemington.

"We've probably look at kicking her off in a seven furlong (1400m) race and see where we get to."

Princess Jenni was scratched moments before the Adrian Knox Stakes at Randwick on April 6 when stewards could not be satisfied she had not received an illegal race day treatment.

After facing two Racing NSW stewards charges relating to race day treatment, Brideoake was cleared at a subsequent hearing, maintaining his clean record.
