Tyson Gavin Forrester, 26, from Shepparton, pleaded guilty in the Koori Court division of the Shepparton County Court to culpable driving causing death.
He also pleaded guilty to the summary charges of being a learner driver who drove without an appropriate supervising driver, driving an unregistered vehicle and using a vehicle without number plates.
Prosecutor Andrew Moore told the court Forrester was driving at a high speed when he lost control of his Ford Falcon BF sedan, crossed the opposite side of the road and collided with trees on Central Kialla Rd at Arcadia on April 3 last year.
The impact caused the car to split in two, and the passenger, a 19-year-old Shepparton woman, was killed.
Forrester walked away from the crash and was found by a taxi driver further down the road, telling her “I’ve got to get the girl out” when they drove past the wreckage, Mr Moore said.
The accused was later flown to hospital in Melbourne for treatment to his injuries.
Mr Moore said the car hit a depression in the road, causing the under-carriage of the vehicle to hit the road surface about 26m from the depression.
He told the court collision reconstruction expert Detective Sergeant Rob Hay said based on the calculations, the vehicle was travelling at “a minimum of 166km/h to 195km/h” at the start of the yaw across the road.
The court was told Det Sgt Hay said the most likely cause of the crash was a “bump steer” where the car was unbalanced after the undercarriage hit the road surface, before leaving the road.
“Had the Ford been travelling at the speed limit, the bump steer or steering input would not have occurred,” Det Sgt Hay’s report said.
Mr Moore told the court a blood sample taken in the hour after the crash showed that Forrester had a “very high” level of methamphetamines in his system.
In a report, Victorian Institute of Forensic Medicine doctor Jason Schreiber said Forrester’s driving skills “would have been adversely affected by the effects of methamphetamine at this level” and that he “would have been incapable of having proper control of the vehicle”.
The court heard Forrester was also a learner driver at the time and did not have a supervising driver with him, and the vehicle’s registration had expired in January 2019.
Victim impact statements were read to the court from the parents, siblings and aunt of the woman who died.
Her mother described her daughter as “an inspirational and passionate daughter who was taken because of selfish actions (of Forrester)”.
“I shouldn’t be missing our girl, every day, every minute, every second,” she said.
“My heart, my mind, my whole life, everything I do, is pained.”
The mother spoke of how she still cried daily and that “no punishment will be enough”.
The woman’s father spoke about how his life changed for ever the day of the crash.
“Telling her mother and siblings was the hardest thing I have ever had to do,” he said.
“One person’s poor judgment ended my little girl’s life.”
Forrester was admonished by Elders sitting as part of the Koori Court, as well as other justice workers who took part in the sentencing conversation in court.
Forrester’s defence counsel Jonathan Barreiro conceded his client “was culpable in a very serious way”.
However, he told the court his client had started using drugs because of a “really difficult upbringing”.
He also said instability in his life and homelessness at the time “led to him making decisions he might not have made”.
Forrester will be sentenced in the coming days.
