They named the character Diana in a homage to the role she played in the show. The character departed on 20 September 2010. Diana is an ambitious, driven businesswoman who works for Lassiter's International. She arrives in Erinsborough from New York on a business trip and decides to try to take control of the company. She also wants to get revenge on the former lover who broke her heart, Paul Robinson (Stefan Dennis). Diana wants to get to the top, but Paul stands in her way as his place within the company is secure. However, Diana discovers that Paul has been embezzling money and uses this to get what she wants. Diana clashes with many of the other Erinsborough residents and she is not well liked. She is described as a "villainess", a "dangerous femme fatale" and a woman on a mission. Diana sleeps with Paul, despite the fact that he is married and she becomes a suspect following an attempt on his life. Badler and Diana were well received by critics.
