Nash Rawiller and Corey Brown will have just one opportunity this week to improve their Sydney jockeys' premiership chances.

Rawiller and Brown will continue to slug it out before a few hundred punters at Warwick Farm on Tuesday but won't be seen in action on a Sydney racetrack for another seven days.

Both will head to Brisbane on Saturday chasing the final Group One race of the Australian racing season - the Winter Stakes.

Rawiller will be on Gold Water and Brown will be hoping to make up for his Stradbroke Handicap heartbreak when he rides Melito in the fillies and mares feature.

Melito was run down in the last few bounds by Black Piranha who claimed his second consecutive Stradbroke.

The title of Australia's leading Group One rider for 2009-2010 is safely in Rawiller's keeping with nine but it's the premiership he wants more than anything.

"Nash has never won a metropolitan premiership - or any sort of premiership for that matter," his agent Glenn Darcy said.

"He's never been in a position to win a premiership because of his weight constraints.

"But after Saturday, Nash will be back to chase the title for sure. That will be his single focus."

Brown pegged back one win at Rosehill on Saturday with a treble to Rawiller's double and he heads into Tuesday's meeting with a full book of seven rides.

Rawiller, who has ridden 74 Sydney winners this season, has four mounts - including three for Gai Waterhouse.

Brown's best chance of chipping away at Rawiller's advantage appears to rest with the John O'Shea-trained Peace Academy.

Peace Academy will be stepping out for the first time since finishing second to Storm Kite at Canterbury on December 30.

Given three barrier trials in preparation for her return, Peace Academy will be trying to enhance a first-up record which includes a narrow defeat to the subsequent stakes winner Silently.

The Anthony Cummings-trained Zanabaa might be the pick of his book as the stayer drops in class on an unplaced Rosehill 1900-metre run on a heavy track on June 5.

While Randwick barrier trials were called off after five heats because of rain on Monday morning, Warwick Farm remained in the dead range with only 1mm of rain in the 24 hours to 11.30am.
