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, known as Bill, remains missing with no new confirmed sightings or developments reported in credible Australian media. The most recent police updates, published on December 11-12, 2025, confirm his last known location as Trigg Beach after taking a taxi from Perth Airport. Western Australia Police continue to express serious concerns for his welfare, particularly in light of family statements about his mental health struggles.

The verified timeline, based on police revelations and family accounts, is as follows:

On December 6, 2025, Carter met his mother, Jenny O’Byrne, for breakfast at the Dome café in Kelmscott. They posed for a selfie around 12:20 pm, which has been widely circulated in public appeals.

At approximately 12:40 pm, O’Byrne dropped Carter off at the drop-off zone outside Terminal 3 (T3) at Perth Airport. He was scheduled for a 2:15 pm flight to Karratha to return to his mining job in the Pilbara. Carter carried only a small 5L backpack, standard for FIFO workers whose main gear is kept on-site.

Carter did not check in, scan a boarding pass, or board the flight. His employer informed his partner, Janae Williamson, that he failed to arrive at the mine site.

Police later disclosed that Carter remained in the airport vicinity for approximately 30 minutes to 1.5 hours (reports vary slightly) before ordering a taxi, which took him to Trigg Beach in Perth’s northern suburbs.

His final confirmed sighting was around 2:40 pm near the Trigg Surf Life Saving Club.

Carter is described as Caucasian, 174 cm (about 5’8″) tall, slim build, with brown hair and blue eyes. He was last seen wearing a black t-shirt, shorts, and white sneakers, carrying a small backpack.

Family members have highlighted Carter’s recent mental health challenges. O’Byrne stated he had stopped taking anti-anxiety medication and described the disappearance as out of character for her “quiet and affable” son. In interviews, she emphasized his vulnerability, saying, “He’s not well, and he’s very vulnerable and at risk.” His phone last pinged between approximately 1:05 pm and 1:45 pm on December 6 before going offline.

No indications of foul play have been reported by police. The investigation focuses on welfare concerns, especially given the coastal location of his last sighting.

Regarding recent online claims of an “exclusive” revelation involving a security log showing Carter pausing for 27 seconds near a restricted corridor, potentially indicating a “voluntary detour or external guidance”—extensive searches across major news sources (including PerthNow, 9News, 7News, ABC News Australia, Daily Mail Australia, and Yahoo News) as of December 13, 2025, find no corroborating reports from police, investigators, or family. Police have not publicly detailed internal airport CCTV footage beyond confirming the drop-off and taxi departure. Such specifics appear unsubstantiated and may stem from unverified social media speculation.

Carter, from Bunbury, attended Bunbury Cathedral Grammar School and Murdoch University before joining the mining industry. He had recently returned from a holiday in Zambia with family. Discussions in online communities, such as Reddit’s r/perth, have noted the demanding nature of FIFO work and its potential impact on mental health.

WA Police urge anyone with information, including dashcam footage from the airport or Trigg area, to contact them on 131 444 or Crime Stoppers anonymously. Mental health support resources include Lifeline (13 11 14) and MensLine Australia (1300 78 99 78).
