A year after four-year-old August “Gus” Lamont vanished from a remote South Australian sheep station, police, politicians and his family are still searching for answers in one of the state’s most baffling missing person cases.
Sunday’s anniversary comes as investigators have renewed their appeal for information, announcing a reward of up to $1 million for information that leads to the conviction of the person or people responsible for Gus’s disappearance and/or the recovery of his remains.
The reward matches South Australia’s highest amount offered in the cold case of the Beaumont children and represents one of the appeals ever made in the state.

Major Crime detectives say 34 calls and two emails were received by Crime Stoppers in the day following the reward announcement. A further nine reports had already been received earlier in the week amid increased media attention surrounding the anniversary.
“Task Force Horizon investigators are pleased with the response we have received so far,” Major Crime Investigation Branch officer in charge Detective Superintendent Darren Fielke said.
Premier Peter Malinauskas said the case continued to resonate well beyond South Australia.
The premier acknowledged the toll the investigation has taken on those closest to Gus, saying: “The untold pain that this has had on his family members is impossible to comprehend.”
Gus vanished from the family’s Oak Park Station near Yunta on September 27, 2025 — AFL Grand Final day.
When the alarm was raised it preceded what became the largest police search in South Australian history.
