Joanna Evans (also Hartman) is a fictional character from the Australian soap opera Neighbours, played by Emma Harrison. Joanna was introduced as the younger half-sister of established character, Annalise Hartman (Kimberley Davies). She made her first on screen appearance on 26 May 1995. Following Davies' departure from Neighbours in 1996, rumours began that Harrison's character would be written out of the show. However, the actress signed a new long-term contract with Neighbours a few months later. In February 1997, producers decided to write Joanna out of the show. A reporter for the Daily Mirror said Harrison was written out due to rows with the producers over her poor acting. Joanna departed on screen on 15 April 1997. In 2005, Harrison was invited to return to Neighbours for the 20th anniversary episode, but she did not appear. Joanna comes to Erinsborough to meet Annalise and introduce her to their father, Tony (Michael Carman). The sisters display different personalities; Annalise is high maintenance, while Joanna is uncomplicated and down to earth. The author of Neighbours: the first 10 years said Joanna was vacuous and branded her as bright as a glowworm. Writers for the Daily Mirror called her glamorous and said she was as just as stunning as her sister. Joanna and Annalise set up their own public relations company, but their first client turns out to be a con man. Joanna's next job was as an aerobics instructor. She followed this with a stint as co-owner of the Chez Chez bar. Joanna has a brief relationship with her sister's ex-fiancé, Mark Gottlieb (Bruce Samazan), before marrying Rob Evans (Graham Harvey). Joanna splits from Rob for a short time when she realises their marriage is loveless, but she decides to leave Erinsborough to reunite with him.
