She will partner with Boom Boom Bella for Lyn Petersen in the opening event at Bundaberg Race Club on Saturday before being legged aboard Might Is Right by trainer Leigh Wanless and Mimmy's Secret for conditioner Kevin Miller.
To round out her four, she has Dashing Hope for Gympie mentor Trevor Thomas in the last on the program.
Simsir believes Mimmy's Secret – who won twice in December of last year – is the best of her chances to nab a debut winner.
Simsir hails from the Glass House Mountains area of the Sunshine Coast and while her family were not involved in racing or had a big interest in horses growing up, she always had her eyes set on a future around thoroughbreds.
“I did showjumping and my parents could never afford a horse, so I went to a riding school where I lived,” she recalls.
“I just kept going, then eventually started going after school and helping the people with the riding school and breaking in trainings and everything.
