A hit-and-run trip to Melbourne for a Group One mile at the Cup carnival is on the cards for Pukekohe mare Postmans Daughter if she runs well in the Spring Classic at Hastings.

The six-year-old mare will be seeking her first group one success in the weight-for-age contest, having run second three times at the elite level in the past.

Trainer Don Walker said he had the weight-for-age Myer Classic for fillies and mares at Flemington on November 2 and the Emirates Stakes, a handicap on the same course a week later, in mind.

The most obvious domestic option would be the Group Two Couplands Mile at Riccarton but Walker has his sights set higher.

"I haven't nominated for that but by the time I pay the late noms and all the travel down to there I can fly to Australia for that sort of money," he told NZ Newswire.

"If you can win a Group race in Australia or even a place in a decent Group race your mare virtually doubles in value, but we'll get this one out of the way first and reassess things."

Postmans Daughter has been in good form this campaign, winning the Group Three Foxbridge Plate first-up over top mares Xanadu and Final Touch before a sixth in the Group One Challenge Stakes at Hastings.

At her last start she ran fifth on unsuitable heavy ground carrying 59kg in the Listed Karaka Classic at Pukekohe and she goes into the Spring Classic one of only four horses rated over 100, along with Survived, Nashville and Zennista.

"She's never gone any good on those heavy tracks. She's always weighed in and never lost ground but she's never made ground," Walker said.

"She's as well as what I've had her, but she's up against good horses and she'll need a little bit of luck in the running."
