Marwooba made the most of an economical run under Melbourne's leading rider Craig Williams to get home from $2.70 favourite Star Of Macedon.
Williams settled Marwooba behind the speed, took a gap midway down the straight and accelerated nicely to open a race-winning lead. The $3.20 second elect scored by half-a-length with Ko Phangan ($7) three-quarters-of-a-length off Star Of Macedon in third.
The win gave Williams victory in the day's two races for juveniles, having won the $150,000 Next Generation Sprinters Series Final (1200m) aboard $2 favourite Stars Of Dom.
Hawkes said attention would now turn to spring with Marwooba, with the Group 2 Bill Stutt Stakes (1600m) at Caulfield on September 27 a possible stepping stone to a Group 1 assignment in Sydney.
"We're very happy to be here in the depths of winter winning a race in July, (he'll go) back to Sydney and have three weeks off probably, then come back into work and he might end up in a Spring Champion (Stakes).
"There are plenty of options for him."
