After showing the jury Air Wing footage of the bush towards Union Spur Track, where Mr Hill and Mrs Clay's remains were found, Crown prosecutor Mr Porceddu said he was moving to another topic of questioning for Detective Florence.
"We'll call it a day," Justice Michael Croucher replied.
Detective Florence is set to continue giving evidence from the witness box from 10.30am on Wednesday.
Mr Lynn had been under police surveillance for almost a year before his arrest for the murders of Mr Hill and Mrs Clay.
Detective Florence detailed how police had put trackers on Mr Lynn's 4WD, surveilling it from December 3, 2020 until the end of May 2021, when the vehicle was being repaired.
The tracker was then returned after those repairs and remained there until Mr Lynn's arrest on November 22, 2021.
A surveillance team also took photos of Mr Lynn's car with the awning attached.
In a picture shown the the jury and taken by the surveillance unit, the beige coloured 4WD appeared to be parked in a suburban street outside some shops, in October 2020.
The jury has returned and Detective Florence is back in the witness box.
Police seized the phone of Mr Lynn's wife Melanie, where they found a picture she'd taken of her husband painting his car from dark grey to beige.
The image was taken on June 4, 2020, just over two months after the alleged murders.
The photo, shown to the jury, depicted Mr Lynn standing at the front passenger side door with a paint roller in his hand, painting the car a fresh colour.
Detective Florence confirmed that Mr Lynn listed his box trailer, which he said carried the bodies of the dead couple, for sale on Gumtree 10 days after the alleged murders.
On that same day, April 1, 2020, he also listed a Jayco Hawk Outback camper and an antique child's bed.
The officer was asked about a photo depicting an awning on Mr Lynn's 4WD when he drove through a camera the morning after the couple's deaths.
Then, 20 months later, the jury was shown CCTV taken outside Mr Lynn's home, on November 19 and 20, 2021.
The accused killer could be seen walking off camera, between what appeared to be his driveway and the front of his house.
In one shot, Mr Lynn was pictured carrying a long item over his shoulder.
"That's the accused with the awning," Detective Florence said, confirming the awning had been removed from the car.
Mr Lynn could then be seen walking back towards his home with a tea cup in hand.
He was arrested by police days after that footage was taken, on November 22, 2021, while camping at Arbuckle.
The jury has been given a short break.
Sketches the accused killer drew during his interview with police included a page titled, 'Truth'.
It featured subheadings for a hypothetical 'doctor', 'tradie' and 'me', denoting Mr Lynn who was a pilot, and the consequences for each of them and their family, career or hobbies if facing the same scenario.
Another page drawn my Mr Lynn was titled, 'Covered up', where he went through the options with police if he distanced himself from the alleged murders.
Mr Lynn marked photos of the Bucks Camp campsite, showing where he burned his gaiters he was wearing when he said both Mr Hill and Mrs Clay died.
Crown prosecutor Daniel Porceddu, questioning Detective Florence, has shown the officer a drawing that was sketched by Mr Lynn during their interview.
The drawing, on a lined notepad, included a calendar at the top with an image depicting a river, a forest, and Mr Lynn and the couple's campsite, along with the locations of Mr Hill's LandCruiser and a toilet.
The police officer confirmed the document was sketched by Mr Lynn, and that he showed the accused killer maps of the high country that he'd marked to locate Mr Hill and Mrs Clay's remains.
Detective Florence said the markings had been made with a "standard issue police pen", causing Justice Croucher to ask whether there was truly such a thing.
"Yes Your Honour, they're not real flash," Detective Florence replied.
Detective Florence has been recalled to the witness stand to continue his evidence.
Mr Lynn's record of interview with police on November 24 and 25, 2020 has been formally tendered to the court, along with a transcript.
The court has adjourned for lunch, and will return at 2.30pm with Detective Florence back in the witness box.
The officers agree that they have no further questions for Mr Lynn.
At that point, Detective Florence turns to the man across the table from him.
"Greg, you're going to be charged with the murders of Russell Hill and Carol Clay," the officer said.
Sitting with his hands clasped together on the table and glasses perched on his nose, Mr Lynn replied, "I understand".
Asked if he wished to say anything in answer to the charges, Mr Lynn said, "I'm innocent of murder".
"I haven't behaved well, I've made some poor decisions, but murder as I understand it, I'm innocent of."
Mr Lynn said his trip to Wonnangatta "was actually my first ever deer hunting trip in the high country".
"I must admit now in hindsight I was ill-prepared for security," he said.
He said normally his guns "would have been all locked up".
He said he'd since purchased lockable bags.
