Gus is thought to have strayed from the property, located approximately 40km south of Yunta, around 5pm last Saturday.
A thorough search has been underway since his family could not locate him, becoming increasingly urgent with each passing day.
Police have revisited the family’s property to examine what is now considered the likely death of the four-year-old boy.
Officers spent over two hours interviewing the family and capturing images around the property.
The police stated that all current evidence indicates the boy’s disappearance is not suspicious.
A family friend condemned what she referred to as “hurtful conspiracy theories” regarding the incident involving the four-year-old.
“Stop with the conspiracy theories,” family friend Fleur Tiver said.
“This child has not been taken. In theory there’s a public road, but in reality there’s six gates on that road out to the highway.”
The team of officers appeared to re-trace and record Gus’s last known movements at the property last night.
The information will form part of their ongoing investigation.
Locals in the region have been left saddened and baffled by the disappearance.
“It’s hard to believe how he could just disappear, in a short circumference of their farmyard, house, station,” local Braithe Selleck said.
“A little boy, four years old, is not I wouldn’t have thought, just got too far away.”
Before it was ended, the search for Gus spanned seven days and an area of almost 500 square kilometres, involving aircraft and teams on the ground.
Each day at least 50 people were involved, but they found nothing apart from a footprint.
Everyone’s thoughts now with the parents, and family, suffering a terrible loss.
“Even the whole community, you know, it’s a very close knit community,” Selleck said.
