Update on the Disappearance of William Patrick “Bill” Carter: Verified Information as of December 13, 2025
As of December 13, 2025, 25-year-old fly-in fly-out (FIFO) worker William Patrick Carter remains missing, entering the eighth day of the search with no new confirmed sightings or breakthroughs reported in credible media. The latest police updates, from December 11-12, 2025, confirm his last known movements: a taxi ride from Perth Airport to Trigg Beach, where he was sighted around 2:40 pm on December 6. Western Australia Police maintain serious concerns for his welfare due to reported mental health issues.
The established timeline, corroborated by police statements and family interviews in major outlets, is unchanged:
On December 6, 2025, Carter met his mother, Jenny O’Byrne, for breakfast at the Dome café in Kelmscott, posing for a selfie around 12:20 pm that has been shared in appeals.

Around 12:40 pm, O’Byrne dropped him off at the drop-off zone outside Terminal 3 at Perth Airport for a scheduled 2:15 pm flight to Karratha.

Carter did not check in or board the flight, and his employer confirmed he never arrived at the mine site.
Approximately 30-90 minutes later, he ordered a taxi from the airport area to Trigg Beach, about 20-25 km north.
He was last confirmed seen near the Trigg Surf Life Saving Club around 2:40 pm.

Carter is described as Caucasian, 174 cm tall, slim build, brown hair, blue eyes, last seen in a black t-shirt, shorts, white sneakers, and carrying a small 5L backpack.
Family concerns center on his mental health; he had recently stopped anti-anxiety medication. O’Byrne has described the disappearance as out of character, calling her son vulnerable and urging public vigilance.
No foul play is suspected. Police continue appeals for information, especially dashcam footage from airport or Trigg areas.
Claims of recent developments—such as volunteers joining overnight searches of the airport perimeter, a new hypothesis of ground-level movement over air travel, private family briefings, or expanded search parameters beyond the terminal—do not appear in any verified reports as of December 13, 2025. Searches across sources like PerthNow, 9News, Yahoo News Australia, Daily Mail Australia, and 7News show no matching updates since the December 12 revelation of the Trigg Beach sighting. Such details may originate from unverified social media or speculation.
Carter’s background includes growing up in Bunbury, attending Bunbury Cathedral Grammar School and Murdoch University, and recent travel to Zambia. The case has sparked online discussions about FIFO industry pressures on mental health.
