A 25-year-old Fly-In Fly-Out (FIFO) worker who went missing after not boarding his scheduled flight at Perth Airport has been discovered dead.

After arriving at the airport, the man spent approximately an hour and a half there before departing in a taxi around 2:10 p.m., heading to Trigg Beach.

He was last seen about half an hour later near a surf club on West Coast Drive.

Today, police announced they have located a body.

Although formal identification is still pending, authorities believe the body to be that of the missing worker, Carter.

Police are not treating his death as suspicious and are preparing a report for the coroner.

Carter’s family had serious concerns about his welfare.

He had smiled in a photo with his mum hours before she dropped him off outside the terminal.
