Australian court orders life without parole

Erin Patterson will spend the rest of her life in prison, a Victoria Court of Appeal panel ruled on Friday.

The three-judge panel dismissed Patterson's appeal and upheld the prosecution's argument that her original 33-year nonparole period was too short. This decision means she is ineligible for release until death. Under the previous sentence, she would have been 82 years old before becoming eligible for parole. Justice Stephen McLeish, speaking for the panel, described the crimes as "extraordinarily cold and calculated" and stated that the "shocking criminality" made a fixed release date inappropriate.

Patterson is now only the second woman in Australian history to receive a life sentence without the possibility of parole. The first was Katherine Knight, a meatworker sentenced in 2001 in New South Wales for stabbing her partner at least 37 times. Patterson's convictions relate to a lunch held in July 2023 at her rural home in Leongatha. She served death cap mushrooms to four guests, resulting in three deaths and one attempted murder. She was sentenced to three life terms for murder and 25 years for the attempt.

Patterson maintained that she added the toxic mushrooms to beef Wellington pastries by accident. However, McLeish found that her intent to kill was sustained for nearly three weeks, beginning when she invited the relatives to dinner. The judge cited an "elaborate series of deceptions," including a false claim of a cancer diagnosis to explain why her two children were absent from the meal. Patterson also destroyed evidence and made repeated false statements about the origin of the mushrooms.

Ian Wilkinson, the husband of one victim, testified at trial that his wife told the guests she wanted advice on how to explain her cancer to their children. Wilkinson, a Baptist pastor, said he felt "half alive" without his wife. He is the sole survivor of the group, having spent weeks in the hospital before being released. The other victims were Don and Gail Patterson, who are Patterson's parents-in-law, and Heather Wilkinson, Gail's sister. Global media attention has since grown around the case, leading to podcasts, books, and a new six-episode series for Paramount+ starring Melanie Lynskey.

Patterson watched the verdicts via video link from the high-security Gordon Unit of Melbourne's Dame Phyllis Frost Centre. She was not present in the courtroom due to security concerns. Her estranged husband, Simon Patterson, had declined the lunch invitation the day before the meal. Pretrial evidence released after her conviction suggests he feared Erin Patterson had previously attempted to kill him. He testified at a pretrial hearing that he declined the invitation out of fear.

Patterson can now appeal to the High Court of Australia, which is her final legal option to overturn the sentence or convictions. Trial judge Christopher Bale, who sentenced her in September 2025, noted there was a "substantial chance" she would remain in solitary confinement for years to come. The court's decision ends the uncertainty regarding her potential release date, cementing her status as a prisoner for life.
