The Erin Patterson Case: Where the Appeal Stands Now

Updated Monday, October 19, 2026.

Three people died after a family lunch in Leongatha, Victoria, in July 2023. They were Don Patterson, Gail Patterson and Heather Wilkinson. Ian Wilkinson survived. In July 2025, a jury found Erin Patterson guilty of three murders and one attempted murder. She is serving life. Her appeal was heard in August 2026. No decision has come yet.

Who they were

The lunch was on July 29, 2023, at Erin Patterson’s home in Leongatha. That is a small town about 135 kilometers southeast of Melbourne (Al Jazeera, July 7, 2025).

  • Don Patterson, 70, was her father-in-law.
  • Gail Patterson, 70, was her mother-in-law.
  • Heather Wilkinson, 66, was Gail’s sister.
  • Ian Wilkinson, 71, was Heather’s husband and a church pastor. He survived after weeks in a coma in the hospital. He later testified at the trial.

Don and Gail were the parents of her estranged husband, Simon Patterson. He was invited but did not go (Al Jazeera, July 7, 2025).

They were parents, grandparents, a wife and a husband. This case is about them first.

Where the case stands today

ItemStatus as of Oct. 19, 2026
VerdictGuilty of three murders and one attempted murder (July 7, 2025)
SentenceLife in prison, with a 33-year non-parole period (Sept. 8, 2025)
Her appealAgainst the convictions. Heard Aug. 19–20, 2026. Decision reserved.
Prosecution appealAgainst the sentence. Asks for life with no parole. Decision reserved.
Decision dateNone announced

The convictions and the sentence stand unless the court changes them. But both appeals are still waiting for a ruling. The case is not fully settled.

The trial and the sentence

Erin Patterson pleaded not guilty to all charges. Her lawyers told the jury the deaths were a terrible accident. They said she panicked and lied to police about where the mushrooms came from. They said she got sick from the meal too (Al Jazeera, July 7, 2025).

The jury did not accept that. On July 7, 2025, the Supreme Court of Victoria jury found her guilty on all four counts.

On September 8, 2025, Justice Christopher Beale gave her three life sentences. She must serve at least 33 years before she can ask for parole. The earliest that could happen is 2056, when she would be 82 (ABC News Australia, Aug. 21, 2026).

The appeals: what was argued

Two appeals were heard together in the Court of Appeal in Melbourne. Three judges heard them: Justices Lesley Taylor, Stephen McLeish and Peter Kidd (ABC News Australia, Aug. 20, 2026).

Her appeal (August 19). Her lawyers raised seven grounds. They say mistakes at trial led to a miscarriage of justice. Key points reported by ABC News Australia (Aug. 21, 2026):

  • The jury hotel. During deliberations, jurors stayed at the same hotel as a police informant and some prosecution lawyers. The defense called this a “catastrophic” error. Prosecutors called the argument “far-fetched.”
  • Photos on an SD card. The trial judge first kept some photos out of evidence. A few days later, he let them in. The defense says that was wrong.

Prosecutors said the case against her was “overwhelming” (ABC News Australia, Aug. 20, 2026).

The prosecution’s appeal (August 20). The Director of Public Prosecutions says her sentence is too light. Prosecutors want life with no chance of parole. They argued the crimes are in the “worst category” (ABC News Australia, Aug. 20, 2026).

The result so far. At the end of the hearing, the judges reserved their decision on both appeals. That means they will rule later, in writing. They gave no date (Times of Australia, Aug. 21, 2026). As of October 19, 2026, we found no public report of a decision.

What could happen next

The court could:

  • Dismiss her appeal. The convictions would stay.
  • Allow her appeal. The court could order a new trial or enter an acquittal.
  • Change the sentence. If the prosecution wins, the court could remove parole or set a longer minimum term.
  • Leave the sentence as it is.

We will not guess which way it goes. Reporting said a ruling could take weeks or months (ABC News Australia, Aug. 21, 2026). Our theory is that it may take longer, because the court must decide two appeals at once. That is a guess, not a fact.
