Katarina Chapman is a fictional character from the Australian soap opera Home and Away, played by Pia Miller. The actress joined the cast in July 2014 following a successful audition. She began filming during the following month, and initially commuted from her home in Melbourne to the set in Sydney. Home and Away marked Miller's first major acting role. She made her first appearance during the episode broadcast on 5 February 2015. The actress was drawn to the part after reading that her character was a strong and resilient policewoman, who was not sexualised in any way. Miller wanted viewers to focus on Kat and not her appearance. The actress filmed her final scenes in August 2017 and Kat was killed off in the season finale, broadcast on 18 December 2017.
