Australian mushroom murderer Erin Patterson begins appeal against sentence

Patterson’s lawyers say trial errors caused a miscarriage of justice, while prosecutors argue her 33-year non-parole term is too lenient.

  • On Wednesday, August 19, 2026, the Supreme Court of Victoria began hearing Erin Patterson's appeal, addressing both her conviction challenge and the Crown's simultaneous push for a stricter sentence.
  • Last year, a jury convicted Patterson of murdering her husband's parents, Gail Patterson and Donald Patterson, and his aunt, Heather Wilkinson, by serving them a beef Wellington lunch laced with lethal death cap mushrooms.
  • Defense counsel Richard Edney and Veronika Drago argue Patterson suffered a "substantial miscarriage of justice," claiming the trial judge erred in evidence admissibility decisions and unfair cross-examination.
  • Director of Public Prosecutions Brendan Kissane simultaneously argues the 33-year non-parole period is "manifestly inadequate," urging judges to eliminate any possibility of future parole.
  • Three judges will hear both appeals over two days in Melbourne, with Patterson watching via video link from the Dame Phyllis Frost Centre, the maximum-security prison in the city's western suburbs.
