Gus Lamont: SA Police to drain large dam on Yunta property as third search begins for missing four-year-old
Police have returned to Oak Park Station to continue the search for four-year-old Gus Lamont, who vanished from his family’s remote sheep station over a month ago.
Following two extensive search operations that yielded no new evidence, police announced on Friday that they will drain a large dam located approximately 600 metres from the homestead.
The dam, which is around 4.5 metres deep, was previously searched by divers in the early days of the investigation. However, police say draining will allow for a “comprehensive visual search”, particularly in areas obscured by underwater vegetation.

The renewed effort follows extensive ground and aerial searches around the homestead since Gus disappeared on September 27.
“Task Force Horizon investigators have concluded assessing data and imagery of the terrain surrounding the homestead that was taken using a dron,” SA Police said in a statement.
“Unfortunately, the imagery has not identified any object of significance that has assisted in the search for Gus.”
Further aerial imaging is underway, covering up to 10km from the homestead. This process is being conducted in stages and is expected to take several weeks, according to police.
On 17 October 2025, police concluded a four-day ground search for Gus. It followed an initial 10-day search with both involving SA Police, ADF members, SES volunteers, trackers and local property owners.
The most recent ground search extended to 5.5km from the homestead, which equates to 95sq/km searched on foot.
The original search area extended well beyond this with the use of the mounted operations unit and PolAir. This area has been estimated at 470sq/km.
Despite hopes that these efforts would uncover clues or indicate the direction Gus may have taken, no evidence has been found.
Police continue to pursue multiple lines of inquiry. So far, investigators have found no indication of foul play.
