No Release Date: Court Removes Parole Path For Mushroom Case

Erin Patterson will remain imprisoned for life without the possibility of parole after Australia's Court of Appeal ruled on Friday that the triple-murderer is not eligible for release. The decision removes the previous schedule that would have allowed a parole review when she turned 82.

The three-judge panel dismissed Patterson's challenge to her convictions and accepted prosecutors' appeal against her original 33-year non-parole term. Justice Stephen McLeish, who wrote for the panel, said the case involved such shocking criminality that setting a minimum period was inappropriate. He called the conduct extraordinarily cold and calculated.

The convictions trace to a July 2023 lunch at Patterson's rural home in Leongatha. She served beef Wellington pastry containing death cap mushrooms to four relatives of her estranged husband, Simon Patterson. Don and Gail Patterson, along with Gail's sister Heather Wilkinson, died within days. Heather's husband, Ian Wilkinson, survived after weeks in hospital.

Patterson received three life sentences for murder and 25 years for attempted murder in September 2025. Trial judge Christopher Bale said at that time there was a substantial chance she could spend years in solitary confinement. She is currently held in the high-security Gordon Unit at Melbourne's Dame Phyllis Frost Centre, a unit for prisoners assessed as at high risk from other inmates.

McLeish said the plan to kill all four guests was sustained for almost three weeks, beginning when she invited them to lunch. He cited an elaborate series of deceptions, including a false claim of a cancer diagnosis used to explain why her two children did not attend. Ian Wilkinson testified that Patterson told the guests she wanted advice on how to explain that diagnosis to her children.

The judge also noted that Patterson destroyed evidence, denied foraging for mushrooms, and repeatedly made false statements about where the mushrooms came from. He described the offense as carefully planned and deliberate, adding that it represented a cruel breach of trust.

Patterson did not appear in court for the ruling. She watched the proceedings by video link from prison. Her remaining legal option is an application to Australia's High Court, which would be her final appeal avenue. Simon Patterson had been invited to the 2023 lunch but declined the day before; he later testified at a pretrial hearing that he stayed away out of fear.

Prosecutors argued at an August hearing that the original minimum term did not reflect what they called the calculated criminality of the case.
