Piper Marilee Willis is a fictional character from the Australian soap opera Neighbours, played by Mavournee Hazel. The actress went through a long casting process, which involved her travelling to Melbourne to audition three times. Months later, she was offered the role. Hazel then relocated to the city from Sydney within three days, so she was available for fittings and filming the following week. Ahead of her first episode, Piper was introduced to viewers in a four-part webisode series called Hey Piper. She made her first appearance in the main show during the episode broadcast on 16 September 2015.
