In 2012, Rachael auditioned for the first season of The Voice Australia with the song "La Vie En Rose". All four coaches turned around and Rachael chose to be on Team Delta, as Delta had been an inspiration to her while she was growing up. She ended up being one of the four finalists on the show. She began singing at an early age of nine, spending a lot of her childhood singing in Italian as a result of spending time with her Italian grandparents.
