"She goes up to 60 kilograms on Saturday, which is always a concern against the better horses," Schweida said.
"I couldn't be more pleased. I wouldn't drop her."
Miss Joelene is rated a $6.50 chance for the Magic Millions Subzero, sharing the second line of betting with Encoder and You Wahng, narrowly behind Sly Boots at $4.80.
Meanwhile, Tony Gollan is following a proven formula with Itchintogo in the Magic Millions 2YO Classic at the Gold Coast on Saturday.
A total of six of the past 15 winners of the $3 million Listed feature have raced on the seven-day backup, despite only accounting for just 16% of the total runners.
Itchintogo, who was a $60,000 purchase at the 2025 Gold Coast March Yearling Sales was an easy winner of the Gold Nugget last week.
It was a run that Gollan said he needed to have.
"I'm really happy with him. It was always the plan, the seven-day backup," Gollan said.
