Raelee Hill is an Australian actress who joined Farscape in its final season to play Sikozu. She had originally auditioned for the role of Grayza, but the producers created the role of Sikozu for her instead. She made her debut in the Season 4 premiere, "Crichton Kicks" and appeared in virtually every Season 4 episode, as well as the mini-series. Despite being a regular, she was only ever credited as a guest star.
