LATEST UPDATE: New Developments in the Case of Missing FIFO Worker William Carter After Perth Airport Sighting
Fresh developments have emerged in the baffling disappearance of William “Bill” Carter, the 25-year-old fly-in-fly-out (FIFO) worker from Bunbury who vanished after being dropped at Perth Airport on December 6, 2025.
WA Police now believe Carter — who was meant to board a flight to Karratha for a work shift — never made it onto the aircraft. Instead, investigators say he ordered a taxi from the airport and travelled to Trigg Beach in Perth’s northern suburbs, where he was last seen near a surf club area on West Coast Drive about 2:40 p.m. that afternoon.
