During the same hearing, at the Melbourne Magistrates’ Court, he also pleaded guilty to breaching an intervention order twice in April 1999.

Charges struck out by the court after Lisa Lynn’s death included making threats to kill her in April 1999 and breaching an intervention order during the same month.

It came during what a court heard was a bitter break-up and custody dispute before Lisa Lynn was found dead on the front lawn of her home.

A coroner found she died, out in the elements, from a combination of prescription drug and alcohol toxicity, while her two young sons remained alone inside the sprawling country home on Zig Zag Road in October 1999. No one was charged over her death.

Following his conviction over the missing campers murder, the court heard Lisa Lynn was his most significant relationship. The pair met when she was 21 and working as an RAAF signals operator, and he was 19.

The pair moved to Western Australia and then Tasmania together, where she was heavily involved in the church, before they moved back to Victoria in the mid to late ’90s.

The court heard that when their relationship fell into difficulties, Gregory Lynn moved out of the family home and began a relationship with another woman.

Court orders were then put in place, limiting his contact with Lisa and their two young sons.

Lynn married his current wife, Melanie, in 2004.

In May 2024, during courtroom conversations when the jury was not present, Crown prosecutor Daniel Porceddu raised calling the family of Lynn’s late wife to testify about his character and how they maintain Lisa Lynn died as a result of his persistent abusive ways.

Porceddu said he had an unsigned statement from the accused, from police records, that had him accepting his prior conduct as allegedly including breaking into his family home, stealing keys and taking a car, and on one occasion, pushing his then wife, Lisa Lynn.

Porceddu also read out a statement from Lisa Lynn’s family, who asked not to be identified.

In it, her father said his daughter feared repercussions from Lynn and lived in terror, so she did not pursue charges against him once they separated.

“When their relationship commenced, everything was good. For some time, Greg wandered in and out of employment with various jobs,” her father wrote to the Supreme Court.

“I was aware of the verbal abuse Greg was always [putting] on Lisa since the marriage began. Before their separation … Greg had been making very serious death threats against her and they continued right through until her death.

“Lisa kept a diary from the day Greg left the marriage … threats and verbal abuse … to the children made by Greg.

“I am also aware the police had to assist Lisa with an [intervention order] as a result of the above and the fact Greg broke into the house and stole the car, leaving Lisa with two young children and no transport … no money. Family court, child maintenance, very messy and bitter from Greg’s side. Greg asking for totally unreasonable demands.”

Porceddu also read a statement from Lisa Lynn’s mother, which said Lynn did not support his former partner after their separation and frequently subjected her to physical and psychological abuse.

“I made many trips to Mount Macedon … to help Lisa with the kids because she wasn’t getting any support from Greg,” she wrote.

“In addition to not gaining any support from Greg, he would subject her to physical and psychological abuse on a frequent basis. Losing his temper for no reason, blaming Lisa for anything that went wrong. He’d yell … things, push her around. I was not inclined to interfere, Lisa pleaded with me not to interfere. Lisa would say to me if I got involved … ‘it would make it worse for me’.

“He has a warped mind, he has done things in the past like to animals and neighbours’ pets, and refused to feed the children. One time, in an uncontrolled rage at the Macedon Hotel, he verbally attacked a man in the bar … then redirected that rage to Lisa when we left the hotel.”

The statements were withheld from the jury as Lynn’s defence team labelled them prejudicial.

Earlier, Detective Senior Constable Brett Florence had been asked about Lynn’s past. He noted some things remained in the police file.

“Mr Lynn’s previous wife was located deceased and there was an inquest in relation to her death. The dossier for that investigation related to that … he was … taken back to the property and while he was in custody escaped from their custody and later arrested,” Florence told a pre-trial hearing.

Florence said police records showed that after Lynn escaped custody, he allegedly hid in the nearby bush and attempted to locate something “hidden” in the Macedon area.

He was rearrested a short time later, the officer said.

“[Police database] LEAP [also] indicated a breach of an intervention order.”

In January 2023, magistrate Brett Sonnet ordered a suppression of the information about the killer’s prior interactions with police, later bolstering the order in November 2024, after accusing one of the country’s largest media organisations of “outrageous, unfair reporting”.

Lawyers for media outlets, including the Herald Sun, ABC and this masthead, appeared in the Melbourne Magistrates’ Court to argue that a suppression order preventing publication should be lifted after Lynn’s conviction.

Instead, Sonnet largely used the hearing to suggest it was the “unified view” of all magistrates and the court that a recent, unrelated Herald Sun story highlighting the topic of deportation at a recent training conference was in error and stooped to the “lowest possible standard imaginable”.

Sonnet said the press had already engaged in extensive reporting of Lynn’s trial and on “almost every matter you’ve been able to do so”, before strengthening the suppression order.

Gregory Lynn is awaiting a decision on his appeal against his conviction and sentence over Carol Clay’s murder.
