Police have provided an update on a new three-day search on an Outback station for four-year-old Gus Lamont, eight months after he went missing.

SA Police have completed a new search for Gus Lamont who was last seen by his grandmother playing at Oak Park Station homestead, about 40 kilometres south of Yunta, on September 27, 2025.
At a press conference today at Yunta, Major Crime Investigation branch officer-in-charge Detective Superintendent Darren Fielke said that one of Gus’s grandparents remained the prime suspect.
Following another three-day search at Oak Park Station around 275km from Adelaide, Fielke said there were no other suspects or persons of interest at this time.
Fielke said abduction was unlikely but none of the theories surrounding Gus Lamont’s disappearance – that he wandered off, that he was abducted or that there was third-party involvement – had been ruled out.
He said this was the eleventh time that Task Force Horizon had searched for Gus at Oak Park Station, with about 17 people searching more than 30 kilometres over the past three days.
“Unfortunately, we have not uncovered any other evidence that helps us locate Gus,” Fielke said.
He said the renewed search was prompted by the wet weather conditions, as they had changed the landscape.
Fielke said most of the search had concentrated on waterways, wash aways and creek beds that had become exposed due to flooding. Police also searched a number of bores and wells within the area.
“The weather conditions and weather events that have happened in this region in the last few weeks have provided us with the opportunity to come back here and to search,” he said.
Fielke said more than 500 people had been identified as being in the area when Gus went missing, but that nearly all of them had been ruled out as suspects.
A detailed search and forensic testing of items on the property had not uncovered any new evidence, but these investigations had not excluded anyone as a potential suspect.
Fielke said that police had received more than 836 separate pieces of information, as well as 527 calls to Crime Stoppers, 200 calls to the Police Communication Centre, more than 60 letters to the Task Force and 60 emails containing information in relation to the investigation.
“It has all been followed up, it has all been investigated, and some of those inquiries have also extended to interstate locations,” he said.
Fielke said police would continue to search creeks and waterways on foot, as well as search the 15 kilometre area surrounding the homestead using aerial platforms fixed with wing aircraft and drones.
The footage captured from the aerial platforms would be sent to a company for AI analysis within the next week.
The disappearance of Gus Lamont was declared a major crime in February this year, with police saying a person living at Oak Park Station when he disappeared was the prime suspect.
Police confirmed his grandparents, his mother and his younger brother were at the property at the time he disappeared, but emphasised his parents were not suspects.
In February, the boy’s parents, Josh Lamont and Jess Murray, said they were united in grief and the search for answers about what happened to their son, who meant everything to them.
“Our lives have been shattered, and every moment without him is unbearable,” they said.
“We know someone out there may have information. If someone knows what happened, we are pleading with that person – or anyone who may have seen or heard anything – to please come forward.”
Anyone with any information on Gus Lamont’s disappearance is urged to contact Crime Stoppers online at www.crimestoppers.com.au or on 1800 333 000.
