"She has been a wonderful mare and I'm glad I got to ride her a couple of starts ago because she has been great for New Zealand racing," says McDonald, who was last week inducted into the New Zealand Hall of Fame.
"But as good as she has been, this is a tough field and my horse [Zaaki] has to be hard to beat.
"Not many horses win good races quite as easily as he did last start."
A former good UK galloper, Zaaki has yet to win over 2000m but the way he jogged home over 1800m last start suggests that won't be an issue.
Still, the class of Sir Dragonet is beyond question and his superstar rider Glen Boss is also going into today's feature event confident.
What does that all mean for Melody Belle and the large contingent of owners who have flown to Queensland to support and ultimately farewell her?
As great a mare as she has been winning 14 Group 1 races, only one of those has been in Australia and even that was in a race restricted to mares.
Even at her career peak she may have struggled to win today's race and for her to come from midfield or beyond to storm past this class of rival really would be a racing fairytale.
Closer to home, the jumps racing season starts to get serious at Te Rapa today with the Waikato Hurdles and Steeples, with Tommyra (Race 2, No 1) and It's A Wonder (Race 5, No 2) trying to complete historic doubles. The pair won the Hurdles and Steeplechase last year, but because of the Covid-delayed programming, the 2020 editions of the race were this season so they are both trying to win the features twice in the same season.
While not huge on numbers, both races boost class, particularly the steeplechase in which It's A Wonder and Mesmerize could dominate.
