Erin Patterson was sentenced to life imprisonment with a non‑parole period of 33 years in the Victorian Supreme Court for the 2023 murders of her in‑laws Don and Gail Patterson and Gail’s sister Heather Wilkinson, as well as the attempted murder of Heather’s husband Ian Wilkinson. Justice Christopher Beale described her actions as involving an enormous betrayal of trust and noted that she had already served 676 days in pre‑sentence detention.

Prosecutors indicated they were considering an appeal against Erin Patterson’s sentence, arguing that the 33‑year minimum term was not sufficiently severe given the gravity of the triple murder and attempted murder. At the same time, her defence highlighted the harsh conditions of her prolonged solitary‑style confinement in the Dame Phyllis Frost Centre, which the judge acknowledged as not sounding very humane.
