Authorities report that a teenage boy without a license was operating the four-wheel-drive when it rolled around 8pm on Saturday night, trapping several passengers inside.
There were six people in the Toyota Landcruiser driving near Logue Brook Dam in Hoffman, about two hours south of Perth.
Passengers were trapped inside the car, their screams heard by nearby campers.
The driver, a 16-year-old, and the surviving passengers – two 16-year-old girls, and two boys aged 18 and 19 – were transported to Bunbury hospital. One of them remained in a serious condition throughout the night.
It was the state’s 86th fatal crash in 2025, the worst at this point of the year in a decade.
Premier Roger Cook issued a plea to drivers.
“Please, when you get behind the wheel of a vehicle understand that you are undertaking an inherently risky and dangerous activity,” he said.
There’s history of reckless behaviour at Logue Brook Dam.
Some locals have called for it to be closed but the Shire of Harvey doesn’t want to.Â
Instead it’s now considering how to improve safety in the area, which will require a mutli-agency approach.
“[It’s] Very tragic news to hear of the passing of such a young person out there,” Shire President Michelle Campbell said.
“Following this unfortunate incident, I am optimistic that we can come together to discuss how to better address similar situations in the future,” said a spokesperson.
