The Inglewood resident was among 14 people worldwide accepted into an acting course at the British theatre school.
Acacia will begin her yearlong course in September.
�I auditioned this year as a practise so I could audition again next year and know what to expect; I was so surprised when I was offered a place,� she said. �I�ve always looked up to British actors due to their versatility and supreme understanding of the craft.
The 21-year-old had specialist lessons at Perth College from years 2 to 12 under the tutelage speech and drama teacher Deb Mitchell.
Ms Mitchell said she was extremely proud of Acacia.
�This is a remarkable achievement; more than 1700 people auditioned for the Bristol Old Vic Theatre School, which is a world-class, highly prestigious training ground,� Ms Mitchell said.
