Waller said no decision had been made on where Winx races next.
“We will see how she pulls up and we said we would take it one run at a time,” he said.
“We are thinking about a Cox Plate obviously and the best way is to take it one run at a time.
“I would say it will be in Melbourne (next) but we will enjoy today and talk about it next week.
“It will be no great surprise I am sure but if we do change it will be for a reason and that reason is the horse comes first.”
Bowman said for a few strides he thought Winx was going to struggle to complete yet another decisive win.
“Le Romain ran a hell of a race and at the corner, I didn’t feel in danger, but I didn’t feel like she was going to be as dominant as she usually is,” Bowman revealed post-race.
“But when that turbo kicked into gear at the 250 metres, it was all over.
“She just knows what she is doing now. I used to control her through the gears, through the race, to help her know when and where to give her full energy but she knows now.
“I suppose I have got to learn with her and understand, and I am learning with her, but it’s the first time I have niggled her around the corner in a 1600-metre race but I guess that’s a couple of things.
“The pace we were going and the class of horses she races against. They are the best in the country.”
Bowman said he attempts to ensure he takes nothing for granted when he wins a race on Winx.
“Without my family here to enjoy the experience it wouldn’t mean as much,” he said.
“She’s brought so much joy to not only those connected with her but far and wide across Australia and the world.
“I know it’s a bit repetitive but the amount of people that approach me and just want to talk about her, and she gives so many people so much to look forward, people that might not have much to look forward to in life, this mare gives them something to look forward to watching.
“She’s just a marvel isn’t she.
“We’ll be lucky to see another one like her, while I’m alive anyway. I think that is a given. How lucky am I to be involved with such a horse?”
For a fleeting moment jockey James McDonald thought he was a winning chance when Le Romain forged clear at the top of the straight.
“I thought I pinched it then I thought Winx is in the race. He’s gone good,” McDonald said.
