AVIGALLE Mendoza had to learn three roles in Opera Australia's South Pacific, despite maybe only performing one.
The nine-year-old is an understudy for two of the three children's parts in the seven-time Tony Award-winning Rodgers and Hammerstein musical.
But she will definitely play assistant to Kate Ceberano's Bloody Mary.
"She was too excited to be nervous," her mother Vicky said on Friday, after dropping Avigalle off for her first night of rehearsals.
Avigalle will join big names, including Lisa McCune as Nellie, Teddy Tahu Rhodes as Emile and Eddie Perfect as Billis.
The St Michael's Primary School pupil trains 11 hours a week at Kidz in the Biz studios in Castle Hill under the direction of Melanie and Keira Noble.
She joined when she was four.
"She does singing, acting, musical theatre, jazz, hip-hop, tap, classical ballet, acrobatics, and is also in our show group and does examination classes as well," Melanie Noble said.
"I just love singing, dancing and performing on stage," Avigalle said.
Ms Mendoza said Avigalle was modest: "She never wants to show her friends or family [what she learns] — I have to ask the teacher first if it's okay for her to show me."
Ms Noble said Avigalle was "sent for the part [in South Pacific] and it was a month before we could tell her that she was chosen".
