Melody Belle finished third in her 1050m trial at Tauranga earlier this month and Bosson said he was happy enough with her run.
"She needed the hit-out, she had a good puff after it. She didn't have the blinkers on, so she would have taken a lot of benefit out of it.
"They went quite fast in the trial and I had to give her a bit of a push along, but she was going the right way and felt good. I had no complaints."
Bosson said the daughter of Commands feels similar compared to the lead-in to her spring preparation.
She finished fourth first-up in the group two Foxbridge Plate (1200m), however, Bosson believes she will be highly competitive today given the feedback he has received from trainer Jamie Richards.
"Jamie said she has come on a lot since she has been in Australia, so I am sure she will be pretty competitive on Saturday," he said.
Bosson is looking forward to riding in Melbourne this weekend and said he will be well-accustomed to airport terminals in the coming months.
"In the next month or two I will be going over there just about every weekend. I really enjoy riding in Australia, it is really good prizemoney which is great. I'll ride in Sydney during the autumn and then go up to Queensland.
"Te Akau will probably be taking some horses to Brisbane, so we will probably head up there for the carnival."
