In March 2010, Monahan stated in an interview with ''
Woman's Day magazine, and later on current affairs television program A Current Affair, that she was sexually abused on the set of Hey Dad...!'' by
Robert Hughes, the actor who played her on-screen father. Hughes denied the allegations and claimed to have engaged
defamation lawyers. During an interview aired on
A Current Affair in March 2011, Monahan expressed her concerns that charges may not be laid against Hughes. She stated that she intended to initiate legal actions against Hughes and television executives who, she claimed, were aware of Hughes' alleged actions and failed to take action. After her allegations in the media,
Braveheart, a sexual assault advocacy group, asked Monahan to become an ambassador. Hughes was arrested in London on 9 August 2012. His
extradition to Australia was approved on 28 September 2012. In early April 2014, Hughes was found guilty of sexually abusing young girls. ==Personal life==
