The disappearance of four-year-old August ‘Gus’ Lamont has gripped the nation and devastated a remote South Australian community, with nearly six weeks of searching turning up almost no trace of the little blond boy.

Gus was last seen around 5pm on September 27, playing outside the Oak Park homestead while his grandmother cared for his younger brother Ronnie inside.

His mother and other grandparent were out tending sheep on the 6,000-hectare property, located 43km south of Yunta in South Australia’s Mid North.

The station is home to around 3,000 sheep and scattered wildlife including feral goats, kangaroos and wallabies.

Search crews have battled scorching heat, rugged hills and sparse vegetation in their efforts to find the missing boy.

Speculation surrounding wild dogs, feral pigs, and birds of prey in the disappearance of the four-year-old remains unsubstantiated.

The region is bordered by the 2,110-kilometre Dog Fence — a critical barrier designed to protect livestock from dingoes and wild dogs.

While feral pigs are known to inhabit parts of South Australia, their presence is typically concentrated further south near water sources.

As for eagles, no species native to Australia possesses the strength required to lift a child. Even the largest birds of prey are limited to small animals such as lambs.

Yunta, a tiny outback town with fewer than 100 residents, serves mostly as a pit stop before the Strzelecki Desert.

Once a bustling hub during the gold rush of the late 1800s, its population has long since faded.

South Australia Police Superintendent Mark Syrus said the weather would have been “uncomfortable” for Gus in the days following his disappearance in September.

Gus was dressed in a cobalt blue long-sleeve shirt with a yellow Minion on the front, light grey pants, a broad-brimmed hat and boots — clothing police initially hoped would offer some protection.

Police Commissioner Grant Stevens said the search had proven more difficult than expected.

“There are lots of places a small child might find themselves which are hard to identify,” he said in September.

The only clue uncovered so far is a single footprint found on September 30 — roughly 500m from where Gus was last seen.

Family friend and neighbour Bill Harbison spoke on behalf of Gus’s loved ones shortly after he went missing.

“This has come as a shock to our family and friends, and we are struggling to comprehend what has happened,” he said.

“We miss him more than words can express.”

South Australian Police Assistant Commissioner Ian Parrott said the family had been spoken about the likelihood Gus wouldn’t be found alive.

“Senior police spoke to Gus’ family and prepared them for the fact that Gus may not have survived due to the passage of time, his age and the nature of the terrain he is missing in,” he said in early October.

“While those involved in the search have been hoping for a miracle, over the past 48 hours, the search has shifted to a recovery operation.”

Gus’s case has since been handed to the missing persons section of the Major Crime Investigation Branch.

Last week, police and SES volunteers drained 3.2 million litres of water from a dam just 600m from the homestead to rule out that Gus may have drowned, his body was not located in the water.

Police Commissioner Stevens on Wednesday reaffirmed the force’s commitment to finding Gus.

“We will be going back to the property to conduct further searches based on further analysis of data and further advice,” he said.

No timeline has been given for a fourth search.

Police have said there is no evidence anyone has harmed Gus, but have not ruled it out.

“There is no evidence of foul play at this time but, as I’ve said publicly before, we are still open to any possibilities that might have resulted in Gus having gone missing,” Stevens said.

Anyone with information about Gus’s disappearance are urged to contact Police.
