"I've been trying to keep up with mum and dad, so to get this is great, as I know they quinellaed the race in 1991," she said.
"I was here as a kid then, so that was pretty cool, not that I remember much. I'm just so rapt and especially for Bill, as he deserved this.
"I'm rapt he entrusted me with the ride as she is as tough as they come. Full credit to her [Glory Days], as the whole race, I was back, and I was mindful of putting myself there on the corner and she just put me there."
Collett is the daughter of Jim Collett and Trudy Thornton, who fought out the 1991 Cup on Star Harvest and Shugar respectively.
Thurlow was struggling to come to terms with the victory as he tried to explain what it meant to him.
"It's just unbelievable, I don't know what to say, but I think the horse has said it all really," he said.
"I was so confident, even going down the back, as I could see she was travelling sweet. Everything went to plan as we'd planned to get her back and let her relax.
"When she circled them and got there, I knew it was going to take a good horse to beat her, as she doesn't know when to stop. We nursed her along and planned to get here and we've done it."
Thurlow will now give Glory Days a few days in the paddock before deciding on where to next, with a lightning trip to Australia to contest the Group 1 Sydney Cup (3200m) a distinct possibility.
"We'll just take her home and see but there's a good chance [of a trip to Sydney]," he said.
Third-placed runner Blue Breeze could also be a surprise Sydney Cup candidate, with co-owner Tony Gavigan indicating they were also considering the transtasman trip with their charge.
With the victory, Glory Days took her career record to 10 wins from 24 starts and over $635,000 in stakes earnings.
