Since Isabelle was a small child, she wanted to be on the big screen, and struggled to see herself pursuing another career. She has an appetite to travel, and would love for her acting to take her to new places across Australia and the world. She studied theatre all throughout high school and enjoyed participating in all the school productions, and was fortunate enough to play a diverse range of main roles. Performing on stage during her high school years was a genuine thrill; she loved the entire atmosphere of theatre. In 2012, Isabelle won the Screen Actor's Studio/Stella Adler Mark Ruffalo Award. The award was a 10-day scholarship to Los Angeles to partake in workshops at Stella Adler and experience American casting directors and agents. She studied at Screen Actors Studio for a number of years, under mentors John McGlynn, Adam Turnball and Maddy French. Throughout her years at Screen Actors she developed a love for acting on screen. She won an audition at Screen Actors Studio to perform a short play at their annual concert.
