Police will provide an update on the search for missing boy Gus Lamont following a three-day hunt for fresh clues at his family’s rural property.

Wednesday marked eight months since the four-year-old disappeared from his grandparents’ home near Yunta in South Australia.

Initial police reports stated Gus had been playing in a pile of sand outside the Oak Park Station homestead, owned by his maternal grandparents Josie and Shannon Murray, and appeared to have wandered off at about 5.30pm on September 27.

Multiple searches have been carried out at the remote property under Taskforce Horizon, but no trace of him has been found.

Major Crime Investigation Branch officer-in-charge Detective Superintendent Darren Fielke will provide an update at the property on Thursday afternoon.

Major Crime detectives and specialist STAR Group officers returned to Oak Park Station on Tuesday, and have spent the last three days searching numerous locations on the sheep station following recent heavy rain.

It marked the first time police had returned to the property since March, where some locations were inaccessible due to flooding.

Footage from the three-day search this week showed up to a dozen officers scouring land near waterways on the 60,000hectare property.

Police had hoped that recent heavy rain may have shifted soil or exposed new ground to uncover potential evidence, including a large-brimmed hat and a Minions shirt that Gus was wearing when he vanished.

SA Police Commissioner Grant Stevens hinted earlier this month that officers had planned to return to the property ‘at some time in the future’.

‘The taskforce operating within Major Crime Investigation Branch is continuing their work,’ he told reporters.

Police have previously described the operation as the ‘largest and most intensive’ missing person search ever undertaken by the force.

In February, authorities announced they believed Gus was dead and declared his disappearance as a major crime, adding they had identified a suspect within the family.

They later confirmed they found ‘inconsistencies’ in statements and timelines provided by some family members.

No arrests have been made or charges laid over Gus’s disappearance.

Police have repeatedly stressed that Gus’s parents, Joshua Lamont and Jessica Murray, are not considered suspects in his disappearance.

Gus’s grandparents, Shannon and Josie Murray – a transgender woman – have both enlisted the services of high-profile Adelaide defence lawyers – a move that is not unusual in these circumstances.

‘(Shannon) is still supporting Josie, cooperating through her solicitors and hoping to find Gus, (and) hoping that some information comes to light soon,’ her lawyer Andrew Ey said.

Gus’s parents, though separated, issued a united statement earlier this year describing how their lives had been shattered by their son’s disappearance.

‘Every moment without him is unbearable,’ the couple said.

‘We know someone out there may have information.

‘If someone knows what happened, we are pleading with that person – or anyone who may have seen or heard anything – to please come forward. Even the smallest detail could give us the answers we so desperately need.’

Gus’s mother was spotted publicly for the first time since his disappearance earlier this month, on a suburban Adelaide street with her youngest child. She politely declined to comment when approached by the Daily Mail.

Anyone with any information is urged to contact Crime Stoppers.
