Victoria Court Orders Erin Patterson to Remain Behind Bars for Life
Appeals judges rejected the 33-year nonparole term, citing the calculated nature of the 2023 poisoning of four relatives in Leongatha.

The Victorian Court of Appeal ruled on Friday that Erin Patterson will spend the remainder of her life in prison. The three-judge panel dismissed the appeals against her murder and attempted murder convictions. They also overruled the original 33-year nonparole period, which would have allowed her to apply for release at age 82.
Justice Stephen McLeish, writing for the court, described the offenses as "extraordinarily cold and calculated." He stated that the case involved such "shocking criminality" that fixing a specific nonparole period was inappropriate. This decision makes Patterson only the second woman in Australian history to receive a life sentence without the possibility of parole.
The convictions stem from events in July 2023 at her rural home in Leongatha. Patterson prepared beef Wellington dishes laced with death cap mushrooms for her parents-in-law, Don and Gail Patterson, and her sister-in-law, Heather Wilkinson. All three died within days of the meal. Heather Wilkinson's husband, Ian, survived after a weeks-long hospitalization. Patterson is the second woman in the country to receive this sentence. The first was Katherine Knight, a meatworker sentenced in New South Wales in 2001 for stabbing her partner at least 37 times.
Patterson maintained that she added the toxic mushrooms to the pastry by accident. Death cap mushrooms account for 90 percent of lethal mushroom poisoning cases globally. The judge noted that Patterson sustained her intent to kill for nearly three weeks, starting from when she invited the group to lunch. He cited an "elaborate series of deceptions" that included a false claim of a cancer diagnosis to explain the absence of her two children.
Ian Wilkinson testified at trial about the loss of his wife. He told the court, "I only feel half alive without her," before weeping. The judge also pointed to Patterson's destruction of evidence and her repeated false claims regarding the origin of the mushrooms. He characterized the crimes as a "cruel breach of trust." Prosecutors had argued in August that the minimum period behind bars did not reflect the "calculated criminality" of the case.
Patterson watched the verdicts via video link from the Gordon Unit of Melbourne's Dame Phyllis Frost Centre. This high-security unit houses inmates assessed as being at high risk from other prisoners. In September 2025, trial judge Christopher Bale noted a substantial chance she would remain in solitary confinement for years. The case has drawn global attention, inspiring podcasts and books. Actress Melanie Lynskey announced this week that she will star in a six-episode Paramount+ series covering the 97 days between the fatal lunch and the arrest.
Her estranged husband, Simon Patterson, declined the lunch invitation the day before the meal. Pretrial evidence released after her conviction detailed his fear that she had previously attempted to kill him. Patterson can still apply to the High Court of Australia to overturn the verdicts. That court represents her final option for appeal.
