Police say they haven't found any evidence that the body of Novy Chardon is buried in the backyard of a Gold Coast Hinterland home.

Detectives began digging up the backyard of a Mount Nathan home about 5pm on Tuesday.

Detective Superintendent Dave Hutchinson said police would spend the day searching the backyard for a ute. He said they had already found vehicle parts.

"I think burying a utility by itself raises suspicions. You have to wonder why they would do that," he said.

"We understand we believe why that occurred and we want to recover the vehicle first to substantiate our thoughts."

Detective Hutchinson said a male occupant of the house had links to Mrs Chardon's husband John, but declined to comment further on their relationship.

It is believed the house is occupied by three people, including one child.

Detective Hutchinson said occupants had given a reason to police as to why they buried the vehicle in the backyard.

But he would not go into detail for operational reasons.

He said police had not made contact with Mr Chardon, who is in Indonesia at the moment.

Police were camped outside the house on Wednesday morning as investigators resumed the backyard search.

Neighbours near the Eden Park Court house said there had been a lot of renovations done at the property in the last year.

Residents were reluctant to give their names out, but said a shipping container sat out the front of the home for eight months, and a new playground was constructed outside the house.

"It's quite disturbing that it's quite close. To think someone could be buried there is wrong," one man said.

"It's just morbid. It's freaky."
