Kylie Ellina Truswell-Mobbs, a 51-year-old woman from Brisbane, has been granted bail after being charged with the murder of her husband, David Ronald Mobbs, who was suffering from motor neurone disease. The case, heard in the Brisbane Supreme Court, has drawn attention to the complexities surrounding end-of-life decisions and assisted dying.
Background of the Case
David Ronald Mobbs, a former firefighter, died at the couple's home in Alexandra Hills, southeast of Brisbane, in December 2023. He had been diagnosed with an aggressive form of motor neurone disease in April 2023, which rapidly deteriorated his condition. Within months, he went from being independent to entirely bedridden, unable to walk or move without assistance. By December, he could no longer speak and communicated through blinking, noises, or a letter board.
According to court documents, Mobbs had expressed to his son, Rylee Relja, that he wanted to end his life if the disease reached a point where he could no longer use the toilet. Justice Paul Smith noted that Mobbs and his family were informed by medical practitioners that his suffering could not be alleviated. Mobbs reportedly said that reaching the stage of needing nappies would be intolerable and humiliating.
Bail Hearing and Conditions
Truswell-Mobbs was initially denied bail in April 2025. However, Justice Smith found a material change in circumstances after a committal hearing in February presented evidence favorable to her. He stated that while Truswell-Mobbs administered the medications, she may have been conflicted about whether she wanted her husband to die, as she loved him and wanted him to live but also did not want him to suffer.
Smith noted that there is now a greater chance she could be acquitted of all charges or found guilty of lesser charges such as manslaughter or assisted suicide. He described her as of exemplary character with no previous convictions and a low flight risk. As part of her bail conditions, Truswell-Mobbs is prohibited from living with or discussing evidence with her sons, who are expected to be witnesses at her trial.
The Incident and Legal Proceedings
The court heard that Truswell-Mobbs admitted to police that she injected her husband's feeding tube with a cocktail of medications to help end his life. On the day of the alleged murder, a palliative care team had informed the family that Mobbs' feeding tubes could be withdrawn and pain managed to allow a natural death over days or weeks. The team also noted that applying for voluntary assisted dying would take at least nine days.
Truswell-Mobbs spent over 12 months in custody before being granted bail. She is scheduled to face trial in the Brisbane Supreme Court at a date to be fixed. The case continues to spark debate on the legal and ethical implications of assisted dying in Australia.
