Two bodies have been found in the search for allegedly murdered Sydney couple Jesse Baird and Luke Davies.
NSW Police Commissioner Karen Webb confirmed this afternoon that police are "very confident" the bodies found at a property at Bungonia are those of Davies and Baird.
Webb said their alleged killer, Senior Constable Beau Lamarre-Condon, had provided information that helped police find the bodies.

"We believe we have located two bodies at that location," Webb said.
"The families have been informed. And crime scene detectives have just arrived on scene at that location now."
Detective Superintendent Daniel Doherty said Homicide Squad detectives attended Silverwater prison to speak with Lamarre-Condon at about 11am today.
"As a result of that, he provided assistance to the investigation and (was) able to provide a location of where Luke and Jesse were," he said.
Two hours later, Doherty said, police went to a location at Bungonia, about 20 minutes from the original search location, and found the bodies.
"There were two surf bags that have been found. And some debris and other items of interest of significance," he said.
Without providing too much detail, Doherty said the bodies were "found upon a fence line, near the entrance to the property".
Police will allege the bodies were transported from the house at Paddington in the surf bags.
"They were covered in debris and the state of the bodies won't be known until we do a proper crime scene investigation, and from there we'll be able to have a post-mortem conducted as well," Doherty said.
Assistant Commissioner Michael Fitzgerald called the alleged murders "horrendous and horrific", and an alleged crime that "probably attracted the world's attention, let alone Australia's".
Doherty said police immediately phoned the families after the bodies were found.
"It's probably mixed emotions for them," he said.
"You can understand how they may have felt.
"But at least they have an answer and they want to travel down to the Goulburn area, and we'll provide as much support as we can and accommodate them."

Doherty said Lamarre-Condon allegedly returned to the Bungonia property to move the bodies the morning after he had first transported Baird and Davies out of Sydney.
It appeared that the serving officer had allegedly tried to cover the bodies with rock and debris, Doherty said.
He said bullets had allegedly been fired from Lamarre-Condon's handgun, but that further forensic analysis was needed to work out the cause of Baird's and Davies' deaths.
A post-mortem would provide "more answers for the family", he said.
Police said no other NSW Police officers, wittingly or unwittingly, had assisted Lamarre-Condon.
Webb said an investigation into the process of checking in and out police issue handguns was underway.
"We're in this position that a police firearm was used. That can never happen again."
Police confirmed Lamarre-Condon has been stood down without pay.
The discovery comes after homicide detectives and specialist resources today searched for evidence in the Royal National Park in an area off Sir Bertram Stevens Drive, near the intersection of Bundeena Drive.
Investigators are conducting inquiries and are continuing to canvas residents and locations in the nearby suburb of Grays Point.
Police confirmed the investigation will continue following the discovery of the bodies.
Yesterday, police divers and teams searched a remote property at Bungonia without success.
A second, smaller search of the property continued today but police divers did not return to scour the property's numerous dams.
Webb earlier told Today Grays Point, where Lamarre-Condon is thought to have left the hired Toyota van he allegedly used to move the bodies, was one search area of particular note.
"That's an area of interest for us," she said.

She called on the public to report if they've seen the white van from Monday to Thursday last week in and around Sydney.
Webb said police divers had finished scouring a dam at the first Bungonia property overnight as officers remained on site to conduct line searches around the area.
"We believe there's still evidence in that area that might link the murders and the victims to that scene," she said.
Anyone with any information is urged to contact Crime Stoppers.
"There is still a lot of evidence out there. There will be evidence that is critical to this investigation, and we need to capture that evidence before it is too late and it disappears," Webb said.
Lamarre-Condon has been charged with two counts of murder and is currently behind bars after being refused bail.
He is believed to have had some prior romantic interaction with ex-Channel 10 presenter Baird.

'Crime motivated not by gay hate'
Webb earlier defended her comments she made at a press conference yesterday, when she said the alleged murder was a "crime of passion".
She told Today it was never her intention to offend anyone.
"It was a crime motivated not by gay hate. But let's be clear, it's apparent and we'll allege that it is a domestic violence stalking and definitely murder," she said.
NSW Police were uninvited from the Mardi Gras Parade this weekend, following days of discussion about whether it would be appropriate for them to march.
It comes in the wake of the alleged murder of the couple by a serving police officer and ongoing questions about the police response to December's report into LGBTQ hate crimes.
Webb said she was disappointed, saying this was a time "more than ever" to unite.
"I'm disappointed that the position of the Mardi Gras board has taken on this issue," she said.
"I think this time, more than ever in our society, it's time to come together.
"We're talking about inclusion, we're talking about diversity and to exclude part of that community, I think sends the wrong message."
