A man aged in his 40s has died after a truck rolled at a quarry in Perth's north-east.
It happened at the Hanson Construction Materials site in Red Hill on Thursday morning.
The Department of Mines, Industry Regulation and Safety has sent investigators to the site.
In a statement, a spokeswoman for the company said the dump truck was travelling along the face of the quarry when it tipped into the pit.
"Today's accident was tragic and our thoughts go out to the driver's family, as well as his friends and colleagues," she said.
Hanson is cooperating with police and is conducting its own investigation too.
Police will prepare a report for the coroner.
