The search for a missing four-year-old has continued almost six month since the child disappeared.

Gus Lamont vanished from the Oak Park Station in remote South Australia on September 27, 2025, sparking several large-scale searches. Police returned to the remote South Australian property on Wednesday, March 11.

A police spokesman said the team would be “searching several locations on the property for evidence in the case”.

Police announced in Feburary that they had identified a suspect believed to be known to Gus. The suspect is not one of Gus's parents.

The case was escalated to a major crime.

Detective Superintendent Darren Fielke said at the time of the announcement that there were "discrepancies" and "inconsistencies" in the information provided by some of the child's family members.

"As a result of these inconsistencies, and investigations into them, a person who resides at Oak Park Station has withdrawn their support for the police and is no longer co-operating with us," Superintendent Fielke stated.

He said that authorities would be returning to the property. They returned to search the property on Wednesday.

Investigators fear Gus is no longer alive.

One hypothesis has been focussed on the possibility of Gus wandering away from Oak Park Station and getting disorientated, but this has been ruled out.

Another line of enquiry focusses on whether Gus was taken by a stranger from the property.
