Gus disappeared while playing near Oak Park Station, roughly 40 kilometers south of Yunta, on September 27.

Despite extensive aerial and ground searches over the past month, he remains missing.

Today, search teams will undertake the task of draining a large dam, 4.5 meters deep, situated approximately 600 meters from the family home.

Earlier in the search efforts, divers had already examined this dam.

Authorities explained that by draining the water, they will be able to conduct a thorough visual inspection.

The search for Gus will resume following exhaustive ground and air searches around the homestead where he disappeared.

Task Force Horizon investigators used a drone to assess the remote terrain, however, it has not uncovered any evidence.

More aerial imaging extending 10 kilometres from the property is still under way.

Taskforce Horizon consists of 12 specialists who are analysing information and suggesting different areas to search.

Police paused their most recent ground search for Gus on October 17.

No trace of Gus was found during this latest search as hot weather hampered efforts.

It followed an initial 10-day search which involved police, military personnel, SES volunteers, trackers and neighbours.

Police said investigations have not uncovered any evidence of foul play.

Gus’ family continues to cooperate fully with investigators.

SA Police Commissioner Grant Stevens previously said no stone would be left unturned in the search for Gus.

“We are dedicated to making sure we do everything we possibly can to bring Gus back to his family,” Stevens said.
