TWO ambulance paramedics sensed there was something suspicious about the scene on Ten Mile Beach after they responded to an emergency call in January 2011.
David Jeffrey and Adam Jarrett were called out early on January 27 to attend to a woman in cardiac arrest.
They arrived at the beach, north of Iluka, just before 7am but found the woman was already dead.
Giving evidence to the coronial inquiry into the woman's death being held at Grafton Courthouse, Mr Jeffrey said when he examined the woman he found no pulse or breathing, and her pupils were fixed and dilated.
"After establishing she was deceased I thought the scene was suspicious and didn't touch the body further," he said.
Mr Jeffrey was concerned by the fact the woman was naked, there were heel drag marks from the water's edge, and there was a large blood clot on the sand up to five metres from the body.
Mr Jarrett thought the woman had been dead for an hour or more.
He remembered a troop carrier-style vehicle seemed to be parked on a pile of debris that had been burnt and covered with sand.
He described one of the men at the scene wearing jeans with what seemed like fresh blood on them.
"Nothing to me made sense," he said.
Mr Jeffrey described two men he spoke to at the scene as appearing "emotionally shocked", "stressed", with "vacant stares" and "pacing around".
"They didn't talk to each other," he said.
One of the men, who he described as short and stocky, wanted to be taken to hospital, Mr Jeffrey said.
"He had told me he was uncomfortable being there."
Earlier the court heard 000 calls that lasted for more than 40 minutes.
The caller told the emergency service, "She just stopped breathing."
"We're trying to resuscitate her, it's not working."
The 000 staff member gave the two men at the scene instructions in how to conduct CPR and encouraged them to keep trying.
One of the men could be hear to say, "F****ing hell, Pauly. C'mon babe, c'mon wake up, where are you."
Rural property manager Nicholas Miller, who was staying at the Black Rock campground, said he saw flames on the beach when he looked for a fishing spot about 5.30am on January 27.
About an hour later a man drove to where he was and asked him to come and help try to revive the woman.
Mr Miller said when he arrived at the scene it looked like the woman had recently been dragged out of the water.
He noticed the vehicle had been parked where the fire had been.
"I thought it was strange. If you've got someone in need you're not going to put the fire out," he said.
The inquest continues.
