Erin Patterson, the Australian woman convicted over the deadly mushroom lunch in Victoria, has two children, a son and a daughter, with her estranged husband, Simon Patterson. The children became part of the widely followed investigation because they were connected to events surrounding the July 2023 beef Wellington lunch that killed three relatives. Although neither child attended the gathering, both later provided information that became relevant during their mother’s 2025 murder trial. Their identities remain legally protected.
How Many Children?
Erin Patterson has two children: one son and one daughter.
At the time of the fatal lunch in July 2023, her son was reportedly 14 years old and her daughter was nine.
Both children were minors when the investigation began, making their privacy especially important.
Australian legal restrictions prevent the publication of information that could identify them.
While the case attracted international media attention, the children were not accused of wrongdoing and should not be treated as public figures.
Their involvement in court proceedings arose from their knowledge of family circumstances and events surrounding the lunch.
Who Is Their Father?
Simon Patterson is the father of Erin Patterson’s two children.
He and Erin were separated before the mushroom poisoning incident, although they remained connected through their parenting responsibilities.
Simon is also the son of Don and Gail Patterson, two of the people who died following the July 2023 meal.
The tragedy therefore affected the children on multiple levels, involving both their mother and their paternal grandparents.
Evidence presented during the trial also described tensions between their parents.
However, private family disagreements should not be confused with the criminal findings concerning the fatal lunch.
The Mushroom Lunch
On July 29, 2023, Erin Patterson hosted a lunch at her home in Leongatha, Victoria.
The guests included her former parents-in-law, Don and Gail Patterson, along with Gail’s sister, Heather Wilkinson, and Heather’s husband, Ian Wilkinson.
The meal included beef Wellington containing poisonous death cap mushrooms.
Don, Gail and Heather subsequently died, while Ian survived after receiving intensive medical treatment.
The incident became one of Australia’s most widely discussed criminal investigations.
Patterson was later convicted of three murders and the attempted murder of Ian Wilkinson.
Where Were the Children?
Erin Patterson’s children were not present at the fatal lunch.
According to evidence discussed during the proceedings, they had gone to the cinema with a friend that afternoon.
Their absence meant they did not eat the meal served to the four adult guests.
This detail became significant as investigators reconstructed the events of the day.
Although the children were not at the gathering, their experiences afterward became relevant to the investigation.
Their accounts helped establish what happened inside the family home in the period following the lunch.
What About the Leftovers?
One of the most discussed aspects of the case concerned food served to the children the following day.
The children reportedly ate leftover beef Wellington after mushrooms had been removed from their portions.
Evidence presented during the trial described how the mushroom component was scraped away before the remaining food was given to them.
Neither child developed the severe poisoning experienced by the adult lunch guests.
However, they were taken to hospital as a precaution because of concerns about possible exposure.
The circumstances surrounding the leftovers became an important subject during the court proceedings.
Their Court Evidence
Pre-recorded interviews with both children were presented during Erin Patterson’s 2025 murder trial.
The recordings allowed the court to consider their accounts without requiring the children to give conventional public testimony in the courtroom.
Their statements addressed family relationships, conversations and events connected to the lunch.
The son’s account included details about tensions between his parents.
The daughter described her mother’s explanation that the gathering involved discussing matters intended for adults.
Their evidence was considered alongside medical findings, forensic material and testimony from other witnesses.
What Did Her Daughter Say?
During the proceedings, the daughter’s recorded account received attention because it included details about her mother’s cooking and the family gathering.
She reportedly described Erin as a very good cook.
She also recalled being told that the lunch was intended for conversations about adult matters.
These statements provided insight into how the gathering had been explained to the children.
However, the daughter’s comments should not be interpreted as evidence that she understood or knew about the poisoning.
She was a child describing events from her own perspective.
What Did Her Son Reveal?
The son’s recorded police interview reportedly described difficulties in his parents’ relationship.
His account provided additional context about the family situation before the fatal lunch.
The prosecution and defence examined a wide range of evidence concerning relationships, communication and the circumstances of the meal.
However, the son’s observations were only one part of a much larger case.
His statements did not make him responsible for the actions of either parent.
The court’s conclusions depended on the overall evidence presented during the criminal proceedings.
Where Are They Now?
Public reports have indicated that the children have been cared for by their father and family members following their mother’s imprisonment.
Their precise living arrangements and day-to-day circumstances have not been established in the information provided.
Because both children were minors during the case, details concerning their schooling, location and personal routines deserve continued privacy.
The public significance of the trial does not create a need to disclose information about their private lives.
The most relevant fact is that they were directly affected by the loss of their grandparents and their mother’s conviction.
Erin Patterson’s Sentence
Following her 2025 trial, Erin Patterson was sentenced to life imprisonment for the three murders and the attempted murder of Ian Wilkinson.
The case attracted worldwide attention because of the unusual poisoning method and the relationships between those involved.
The criminal proceedings also brought considerable scrutiny to her family circumstances.
However, the sentence should not be confused with a determination about the children’s future or their individual welfare.
Those matters remain separate from the criminal case and subject to appropriate legal protections.
Final Thoughts
Erin Patterson has two children, a son and a daughter, with her estranged husband, Simon Patterson.
Neither child attended the July 2023 mushroom lunch, although both later provided recorded evidence during their mother’s trial.
Their experiences became part of a major Australian criminal case involving the deaths of three family members.
While public interest in the investigation remains strong, the children’s identities and private lives deserve protection, particularly because they had no responsibility for the crimes.
Their story is an important reminder that high-profile criminal cases can have lasting consequences for family members who were never accused of wrongdoing.
