Brook started ballet at a local school in Sydney at the age of three. She then moved on to train in the RAD syllabus at the Redlands Ballet and Dance Academy under esteemed teachers such as John Byrne, Kim Traynor and Kit Lethby. Competing as a classical ballet soloist in eisteddfods across Sydney during this time allowed her to explore and develop her own artistry. Throughout high school, Brook also indulged in other styles of dance including lyrical, jazz and hip hop. Since moving to Canberra in 2013 to study Law/Asia-Pacific Studies at the ANU, Brook has continued her passion for dance at the Canberra Dance Theatre.
