The Emma Stewart and Clayton Tonkin Group 1 juggernaut rolled on earlier in the night when Amore Vita came from the clouds for a last-stride win in the mares' feature, the Golden Girl.
The former Kiwi had always shown ability and was a multiple Group 1 winning filly but had also been let down at times by her immaturity.
But Amore Vita has grown up this season and it was a much more professional mare that lined up on Saturday night, relying on her class and will to win to get her home over Manhattan and Delightful Angel.
It was a 133rd win for driver Chris Alford who said the mare had to call on her reserves to find a way to win.
"That was terrific. She had to do a lot of work and she was all out at the 400m but she was still digging in to the line."
"She's always been pretty fast but she's so strong now… she just keeps on going."
Stewart was also full of praise for her mare's bravery.
"If they all tried as hard as her it would make life a lot easier."
The win continued the stable's success from their first Constellations carnival last year when they claimed the Rising Sun and Queensland Oaks.
Emerging local gelding Speak the Truth earned a tilt at the $2.1 million Eureka at Menangle in September with his victory in the night's other feature, The Hayden.
It was the inaugural running of The Hayden, a slot race for Queensland bred and trained three and four year-olds with the Eureka berth a bonus for the winner.
Speak The Truth engaged in a battle with fellow in-form gelding Captain Shuffles but got the upper hand late to win the $231,000 race for trainer Shannon Price and driver Adam Sanderson.
