BRISBANE — Kylie Ellina Truswell-Mobbs was granted bail by the Brisbane Supreme Court in May 2026 after being charged with murder. The charge followed the December 2023 death of her husband, David Ronald Mobbs, at their Alexandra Hills residence after she administered a medication injection.

Ms. Truswell-Mobbs had been denied bail in April 2025. Justice Paul Smith ruled that favorable evidence presented during a February 2026 committal hearing constituted a material change in circumstances. He indicated that a jury could potentially acquit Ms. Truswell-Mobbs or convict her of lesser charges such as manslaughter or assisted suicide. Ms. Truswell-Mobbs will stand trial at the court on a date not yet determined.

David Ronald Mobbs, a 56-year-old former firefighter, was diagnosed with motor neurone disease in April 2023. By December 2023, he was bedridden, unable to speak, and communicated using eye blinks, vocalizations, and a letter board. He was physically unable to administer medication to himself. Justice Smith said, "David and his family were informed by medical practitioners they could not alleviate his suffering." He said, "He had communicated to others that should he reach the point of needing nappies, this incapacity and humiliation would be intolerable to him."

Ms. Truswell-Mobbs admitted to law enforcement that she injected a medication cocktail into her husband's feeding tube. Mr. Mobbs had previously told his son, Rylee Relja, that he would want to end his life if his illness progressed to requiring incontinence care. A palliative care team informed the family hours before Mr. Mobbs died that discontinuing feeding tubes would result in a natural death over several days. A palliative care team stated that the voluntary assisted dying application process requires a minimum of nine days.

Ms. Truswell-Mobbs was held in custody for over 12 months before her bail approval. Her bail conditions prohibit her from living with her sons or discussing case evidence with them, as her sons are scheduled to testify as witnesses at her trial. Justice Smith said, "She is of exemplary character and has absolutely no previous convictions. There is very little flight risk."

No independent assessment of Kylie Ellina Truswell-Mobbs’s claims was available.
