Winx is a rock-solid A$1.10 favourite for the Queen Elizabeth after the champion mare drew ideally in barrier three for the Randwick feature.
Winx will face just eight rivals in the race in what looks certain to be another walk in the park for the queen of the turf.
Winx's part-owner Debbie Kepitis said all was in order for Saturday's big race.
"She had a great gallop [at Randwick] on Saturday and she looked amazing," Kepitis said.
"Everything is ticking over, as it should be, and the nerves are building up, as they should be."
Hartnell, considered Winx's biggest danger at $11, drew barrier one. "He has a nice spring in his step and I feel John [O'Shea] has him the best he can get him," Godolphin's racing manager Darren Beadman said.
The United States ($15) drew barrier seven, while Happy Clapper ($21) will jump from gate five.
