Scott Aspery has confirmed the Sensational Sunday feature will be the main autumn aim for Magic Millions Guineas runner-up Estonian Princess.

Only Gai Waterhouse's classy Sweet Idea beat home the $65,000 yearling on the Gold Coast and Aspery is intent on bringing the Snitzel filly south for Kembla Grange's biggest race.

"If she comes out and blows us away in what she did [in the Surround Stakes] she may go to the Coolmore [Classic], but more than likely the Keith Nolan will be the race we target," Aspery said.

"Obviously the Keith Nolan is the main target, but if she's going well enough we may even push onto the Adrian Knox and Oaks if she's ready for it."

Possibly even more worrying for Estonian Princess's rivals is Aspery consulting master horseman Guy Walter about plotting a path through the autumn for a filly.

Walter's Victoria Oaks runner-up Zanbagh is likely to line up in the Nolan as the veteran shoots for a fifth win in the race.

"Guy is a bit of a master with fillies and mares ... and he's of the opinion you don't need a staying filly to win an Oaks," Aspery said. "It's usually the best horse in the race wins it.

"She's a very busy horse and her racing manners aren't there yet and if she learns to relax in her races and not worry about what everyone else is doing then I can't see why she couldn't get out to 2000 [metres]."

The Illawarra Turf Club last week announced a prizemoney hike for their flagship event, lifting the total purse to $200,000.

It means the mile event will stay on comparable terms with the Group 3 Adrian Knox Stakes (2000m), a traditional Oaks tune-up three weeks later.
