Today, a significant update is anticipated from South Australia Police regarding the search for missing toddler Gus Lamont. The announcement will be made by Detective Superintendent Darren Fielke, the Officer in Charge of Major Crime, during a press conference scheduled for 1 p.m. local time (1:30 p.m. AEDT).

Gus was last spotted at his grandparents’ expansive property, Oak Park Station, which spans 60,000 hectares and is located 40 kilometers south of Yunta. The toddler disappeared on September 27 while under the care of his grandmother, Shannon Murray.

At the time of his disappearance, Gus’s mother, Jessica, and grandparent Josie were approximately 10 kilometers away, attending to sheep. According to police reports, Shannon was the last person to see Gus around 5 p.m. as he played in the sand outside the homestead.

She noticed the toddler was missing when she went to call him inside about half an hour later, at which point he had vanished without a trace.

Police said Shannon was the last person to see Gus, at about 5pm, when he was playing in the sand outside the homestead. 

When she went to call him inside about 30 minutes later, he had vanished without a trace. 

The family reported Gus’ disappearance to police three hours later.

At the time Gus went missing, his father, Joshua Lamont, was living about two hours away from Oak Park and was not present when his son disappeared. 

South Australia Police are expected to make a huge announcement today in the search for missing toddler Gus Lamont

Gus went missing form his family’s sprawling sheep property in the middle of nowhere in outback South Australia, nearly 200 miles north of Adelaide

A friend told Daily Mail that Joshua and Jess remain a couple but have a ‘commuter relationship’. 

Although hundreds of police officers, dozens of soldiers, a small army of volunteers and an Aboriginal tracker have scoured tens of thousands of acres of Outback, the blond, curly haired little boy has not been found.

The only trace of Gus was a single footprint found about 500 metres from the homestead – which police have since cast doubt on.

There is little hope he will be found alive.

At the time of his disappearance South Australian Assistant Police Commissioner Ian Parrott said said they believe that Gus wandered off and was not taken, as the only people who travel on the nearby road are station owners.

‘Everything that we have found to date, every piece of information and evidence that we have explored to date, indicates that, as best as we know, Gus has wandered off from this property and we have not been able to locate him.’

Locals believe the four-year-old may have fallen into a disused and unmarked mine.

The area is dotted with mines and wells from more than a century ago. 

The mines were used as water sources for livestock and those hunting gold, with many being invisible to the naked eye.  

Police have discounted several theories that might explain the four-year-old’s disappearance, not least those involving animals. 

While dingos have been responsible for abducting small children, there are precious few in the land around Yunta, since sheep farmers tend to shoot them on sight. 

The region is also protected by a 1,200-mile dog fence designed to safeguard livestock. Crocodiles, which inhabit more tropical northern regions of Australia, are not found in the south.

Gus is too big to be taken by an eagle, and if he had been attacked by a wild pig, searchers would almost certainly have discovered evidence of a struggle.

Local topography, meanwhile, makes it almost impossible that a stranger could have abducted him. 

The nearest major public road is the Barrier Highway, a desolate 600-mile road that takes long-distance truckers to New South Wales. But to reach it, Gus would have had to wander 48km.

Police divers have searched every pond and water tank in the area.
