The facts
The court dismissed Patterson's challenge to her convictions and granted the prosecution's separate sentence appeal on 30 October. [1][2][4]
She was convicted of murdering Don and Gail Patterson and Heather Wilkinson, and attempting to murder Heather's husband, Ian Wilkinson. [1][3]
The original sentence, imposed on 8 September 2025, was life imprisonment with a minimum of 33 years before parole eligibility. The appeal court removed that minimum and imposed life without parole. [3][1][4]
The appeal court rejected the remaining challenges involving jurors staying at a hotel also used by a police witness and the admissibility of mobile-phone evidence, ABC reported. [1]
Relevant context
The convictions concern a July 2023 lunch at Patterson's home in Leongatha, Victoria, SBS reported. [4]
Still unconfirmed
- Whether Patterson will seek to challenge the result in the High Court remains unresolved.
