Chris Waller believes Red Tracer can build on her first Group One win in the Tattersall's Tiara at Eagle Farm on Saturday.

Waller ruled out any thoughts of retirement for Red Tracer and says there is no reason why she can't add to her Group One tally next season.

"It takes so long to get horses of this calibre and she's the type who could be competitive in these types of races for at least another season," Waller said.

"She hasn't been heavily raced. She's in career-best form and is the soundest and healthiest she's ever been."

Waller said Red Tracer's Group One triumph was an appropriate reward for the consistency she has shown throughout her career.

"No horse deserves it more than her and I doubt there's a person anywhere who would deny her this win," he said.

"It's great to see her finally get that Group One because she's never had a lot of luck in some races at this level."

Red Tracer was bred and is owned by long-time stable supporters Geoff and Mary Grimish which was of special significance for Waller.

"It's great to win for them because they've been loyal supporters of my stable right from day one," he said.

Red Tracer was the ninth Group One win of the season for Waller, who typically deflected most of the praise to his staff.

Jockey Nash Rawiller was impressed with the acceleration of Red Tracer ($4.80) who scored by 2-1/4 lengths from the favourite Streama ($4.40) with Floria ($21) a short head away third.

"I haven't had a horse let down like that for me in a Group One for a long, long time," Rawiller said.

"From the time we left the barriers she was in a beautiful rhythm and I wasn't troubled by covering a bit of extra ground because she was travelling so well."

Hugh Bowman, who rode Streama, was pleased with the mare's performance but felt the going near the fence contributed to her defeat.

"The track is playing just that little bit better out wide but to her credit she kept trying right to the line," he said.
