Her mother Julie is a classically trained pianist and guitarist and as a result, Sursok was brought up surrounded by music. At a young age, Sursok was involved with the Sydney Youth Musical Theatre, where she pursued her interests in acting, music and dance. She also studied with the Trinity Speech and Drama College and graduated with a high distinction. Sursok was educated at Ravenswood School for Girls, in Gordon, Sydney, studying speech and drama in her final years of school. She won her part in the long-running Australian drama series, Home and Away at the end of 1999 after completing Year.
