Erin’s relationship with in-laws ‘tense’, Simon tells court
Jurors have been shown messages between Simon and Erin between 14-15 October 2022 exchanged on the app Signal.
Simon says there was “a lot of tension” in his relationship with Erin at this point. He says her relationship with his parents was also tense.
In the messages shown to the court room, Erin says she is “very very hurt” she was not invited to Simon’s mother’s 70th birthday. Simon says this was due to a misunderstanding with his father, Don.
In a message to Erin on 14 October 2022, Simon says:
Hey are you coming to mum’s Birthday lunch.
Erin says she is not aware of it, to which Simon replies he thought his father had invited her. But says his father may have gotten mixed up.
Erin replies:
I’m not too sure how your dad could have been confused….. Seems that my invite tomorrow is a bit of an afterthought and not even from your parents so I might pass thanks…
She later messages Simon:
What I recon is everybody forgot to actually invite me to this thing and I feel very very hurt about that..
Simon says Erin is free to “choose to think whatever you want”. But he says the birthday event is “very important” to his mother, Gail.
Erin later messages that she’ll attend the lunch and will bring their children.
The following evening, Erin sends a message to Simon:
I’m sorry for shouting at you this afternoon. I was feeling very hurt and lashed out… I’d like to not do that again.
Simon says “thanks for that” and says he is “sorry I raised my voice and tone too”.

Court shown more Signal messages between Simon and Erin Patterson
The court is being shown more Signal messages between Simon and his estranged wife, Erin, between 21 November 2022 and 15 August 2023.
The first message in November 2022 is Erin writing to Simon about their son’s surgery and an anaesthetist bill.
She requests Simon pay the bill.
Simon replies:
The department of human services instructed me not to pay you anything for the kids from now on, so I cannot pay that, I’m afraid.
Erin replied that the payment is not to her but to the anaesthetist.
Simon says this is “exactly the kind of thing they explicitly instructed me not to pay for”.

Simon Patterson agrees Erin ‘hates hospitals’
Simon is being questioned about Erin’s actions at Leongatha hospital after the mushroom lunch.
Under cross-examination by Mandy, he agrees Erin “hates hospitals” when asked about her leaving the hospital against medical advice.
Mandy also tells Simon there was “some sensitivity” about the need for their children to attend the hospital.
Simon agrees, saying his two children both had past experiences with hospitals which were “difficult”.
Simon Patterson says he didn’t ask his father ‘lots of questions’ about what he remembered about the lunch
Mandy questions Simon about a conversation he had with his father, Don, on 30 July when he was hospitalised after the mushroom lunch.
Mandy says at this point Don had been “distressed, physically, for a long period of time”.
“You couldn’t and didn’t ask him lots of questions about what he remembered about the lunch,” Mandy says.
“That’s correct,” Simon replies.
Mandy puts to Simon that Don told him about Erin’s potential cancer diagnosis rather than a “certainty.”
Simon says his understanding was that Don said Erin had been diagnosed with cancer.
“That wasn’t in doubt … how to treat it is where the uncertainty was.”
Mandy reiterates that Don told Simon about Erin’s “suspected diagnosis” rather than a “confirmed diagnosis”.
Simon disagrees and says this is highly unlikely.
Erin ‘struggled a lot with mental illness’, Simon says
Mandy says Simon did not contact Erin after the lunch to inquire about the “medical issue” she had mentioned.
“Is it not the case over the years that Erin often complained about medical issues and thought she was unwell for various reasons?” Mandy asks.
Simon replies: “Yes.”
Mandy suggests these were unsubstantial. Simon says Erin told him she struggled with a heart condition which affected her sleeping.
“I have no reason to disbelieve that,” he says.
Simon says this required hospitalisation at times.
“She struggled a lot with mental illness, postnatal depression … I believe that was real,” he says.
Mandy says in October 2021 Erin expressed concern about having ovarian cancer.
“Erin has never told me she had ovarian cancer,” Simon says.
Mandy has now turned to Erin inviting Simon to the mushroom lunch which was held on 29 July 2023.
Mandy points to Simon’s evidence yesterday that Erin had informed him she had “important” and “serious” medical news to share when she invited him to lunch.
“Let me put this to you, Erin did not say the words ‘important’ or ‘serious’ when she spoke to you that day,” Mandy says.
Simon replies that he can’t remember the exact words she said but that “important and serious are reasonable descriptions of what she communicated”.
Mandy suggests that the words “important” and “serious” were not used in his police statement.
Simon does not refute this.
Mandy begins by asking Simon about the relationship between his parents and children.
He shows the courtroom a video, showing Simon’s son and his father, Don, playing with a rocket-propelled car in the back yard. Mandy says it was captured on 17 July 2023 – weeks before the fateful mushroom lunch.
As he’s shown the video, Simon wipes away tears from his eyes.
Simon Patterson returns to witness stand
Simon Patterson is back in the witness stand in the courtroom.
Erin Patterson’s lawyer, Colin Mandy SC, is continuing his cross-examination of Simon.
We’re waiting to begin.
Our reporter Nino Bucci was in the courtroom yesterday on day three of Erin Patterson’s murder trial, when her estranged husband Simon Patterson started his evidence.
Here’s Nino’s report filed from Morwell in Victoria’s Gippsland region:
Day three recap
Before today gets under way, here’s a recap of what the jury heard yesterday:
1. Text messages shown to the court on Thursday revealed Erin had texted Simon on the eve of the mushroom lunch, saying she had spent a “small fortune” on buying eye fillet steak for her “special meal” of beef wellingtons. She said she hoped Simon would change his mind after he turned down the invitation.
2. Simon recalled Erin saying she had conducted a “blind taste test” with her daughter by putting dehydrated mushrooms in muffins. He told the court Erin remarked it was “interesting” that their child preferred the muffin that contained mushrooms given she didn’t like mushrooms.
3. Jurors also heard details about Erin’s relationship with Simon’s parents. He told the court Erin was particularly close with his father, Don.
4. Asked about Erin’s self-esteem, Simon said his estranged wife was “not particularly happy with how she is”.
“I don’t think she has high self-esteem,” he told the court.
5. Simon recalled Erin’s mixed plate collection at her home in Leongatha. Under cross-examination, he described her collection, saying there were some plates that matched and a single colourful plate.
Welcome to day four of the trial
Welcome to day four of Erin Patterson’s murder trial.
We’re expecting the trial to get under way at 10.30am. The court will wrap up at 1pm today.
Patterson, 50, faces three charges of murder and one charge of attempted murder relating to a beef wellington lunch she served at her house in Leongatha, regional Victoria, in July 2023.
She has pleaded not guilty to the charges. The defence’s case is that the events were an accident and Patterson never intended to harm her lunch guests.
