Heine was born in Johannesburg to South African parents Michelle, a former showgirl, and Kevin Heine. She moved to Australia at the age of three with her parents and older brother Kyle (born 1985).
Her early days included training in jazz dance, tap dance, classical ballet, acrobatics and rhythmic gymnastics, and studying acting and singing at National Capital Acting School. She danced at her mother's dance school in Canberra, where she later attended Telopea Park School and St Clare's College. She was the youngest dancer to perform at the Stargazers Convention in Sydney, Australia. She was homeschooled to focus on her dance career, and performed in many stage productions, including a tour in the United States, where she featured in the music video for Will Young's song "Leave Right Now". After a serious hip injury, she was suggested to turn temporarily to acting by her manager.
